Enterprise Tenant

The Enterprise Tenant of the Cumulocity IoT platform provides several enhancements to the features for the Standard Tenant. The following sections describe additional functionalities available in the Enterprise Tenant.

Managing tenants

Using the Enterprise tenant of Cumulocity IoT, you can make use of the tenants functionality which allows you to create and manage subtenants.

Important: There is a major difference between providing several tenants and providing several users with different permissions within a single tenant. Tenants are physically separated data spaces with a separate URL, with own users, a separate application management and no sharing of data by default. Users in a single tenant by default share the same URL and the same data space. So if your users, for example, are separate customers of yours and you need to strictly separate them because they may be competitors, we strongly recommend you to do so by working with tenants.

Info: If you would like to use this feature, please contact product support.

To be able to use the tenant functionality, your user needs to have the appropriate permissions. See Creating and editing global roles for information on editing permissions. Since editing tenants is a sensitive operation, permissions for editing tenants are more granular:

To view subtenants

Click Subtenants in the Tenants menu to view all subtenants available in your account, either in a grid or a list.

The Tenants page provides the following information on each subtenant:

In the management tenant, you will also find information on the parent tenant, i.e. the tenant that created the listed tenant.

To create a subtenant

  1. Click Create tenant at the right of the top menu bar.

    Create subtenant

  2. Provide the following properties:

    Field Description
    Domain/ URL Enter a subdomain of your choice, for example "acme". The tenant's URL will be "acme.cumulocity.com" on cumulocity.com. You can only use one subdomain level. For example, you can only use "acme.cumulocity.com" on cumulocity.com. You cannot use "mycustomer.acme.cumulocity.com". This is not permitted by the TLS standard.
    The tenant domain may contain lowercase letters, digits or hyphens. It must start with a letter; hyphens are only allowed in the middle; minimum is 2 characters. Note that the usage of underscore characters is deprecated but still possible for backward compatibility reasons.
    Name The name of the tenant, e.g. the company's name.
    Administrator's email You must provide a valid email address to enable users to reset their password.
    Administrator's username Username for the administrator of this tenant.
    Contact name Optional name of the contact.
    Contact phone Optional phone number of the contact.
    Send password reset link as email Selected by default. If you deselect this option, you need to provide a password and confirm the password (see Getting Started > Accessing and logging into the Cumulocity IoT platform for more information on password strength).
    Tenant policy You may select a tenant policy to be applied to the tenant from the dropdown list.
  3. Click Save to apply your settings.

When the subtenant is created, it gets an auto-generated ID, which cannot be changed. Also, it is automatically provisioned with a first, administrative user (“Administrator’s username”). This administrator can create other users and set their permissions. The first user cannot be deleted to prevent you from locking yourself out.

From the management tenant, you can enable other tenants to create subtenants. To do so, check Allow creation of subtenants in the tenant editor.

To view or edit subtenant properties

Click on the desired subtenant or click the menu icon at the right of the subtenant entry and then click Edit.

In the Properties tab, all fields are editable except of ID, Domain/ URL and Administrator’s username. For details on the fields, refer to Creating sub-tenants.

To change the tenant password, click Change password, enter the new password in the upcoming fields and click Save.

Support user access

At the right of the Properties tab, you can find information on the support user requests/access for the subtenants.

Support user access information

The following information is displayed here:

Field Description
Status May be either “Enabled” or “Disabled”.
“Enabled” indicates that:
- support user access has been activated globally in the Management tenant (see Administration > Platform configuration settings),
- one or more subtenant users have activated support user access.
“Disabled” indicates that:
- support user access has been deactivated globally in the Management tenant,
- no subtenant user has currently any active support user access (i.e. as each support user request has either expired or has actively been deactivated).
Active requests count The number of requests currently active in the subtenant. Only displayed if support user access is not enabled globally in the Management tenant. Shown as a number in a small red dot.
Expiry date Specifies the date on which support user access for the tenant will expire. If no date has been specified, the expiry date is set to “No limit”.

Suspending subtenants

Suspending a tenant blocks any access to this tenant, regardless whether the access is from devices, users or other applications.

If a tenant is suspended, the tenant’s data remains in the database and can be made available later by clicking Activate.

Important: Suspended tenants for all Cumulocity IoT public cloud instances will be automatically deleted after 60 days.

Info: If data broker connectors are configured for a tenant, suspending this tenant results in suspending all its data broker connectors as well.

To suspend a subtenant

  1. Click the menu icon at the right of the respective subtenant entry and then click Suspend.

    Suspend tenant

  2. In the resulting dialog box confirm the suspension by clicking OK and entering your password.

As part of suspending the tenant, an email is sent to the tenant administrator if an email address is configured for that administrator.

Info: If you are a service provider, you can suppress this email.

Deleting subtenants

Important: Deleting a subtenant cannot be reverted. For security reasons, it is therefore only available in the management tenant. You cannot delete tenants from any tenant but the management tenant.

Administrators in Enterprise Tenants are only allowed to suspend active subtenants, but not to delete them.

To delete a subtenant

Click the menu icon at the right of the respective subtenant entry and then click Delete to finally delete a tenant and remove all the data of the tenant.


In the Applications tab you can view all subscribed applications, subscribe tenants to applications or remove the applications from the tenant. By default, tenants will be subscribed to the standard Cumulocity IoT applications.

Subscribe tenant

To subscribe an application

Hover over the applications under Available applications at the right and click Subscribe on the desired application.

To unsubscribe an application

Hover over the applications under Subscribed applications at the left and click Unsubscribe.

Monitoring microservices

For all applications hosted as microservices by Cumulocity IoT the status of the microservice is indicated next to its name by symbols:

Application details

The microservice may be in one of the following states:

You may view details on their status by expanding the respective entry.

Application details

The following information is provided:

Further details are provided on the Status tab of the respective application, see Administration > Managing applications.

Custom properties

The Custom properties tab allows you to view and edit values of custom properties, either predefined ones (like “External reference”) or those defined in the Properties library. Such properties are also displayed as columns in the Usage statistics page.

Custom properties

Limiting subtenant device number

Platform administrators can limit the count of concurrently registered root devices or simply all devices (including children devices) via the custom property “Limit number of devices”.

They can view the peak number of concurrently registered devices, root devices and the peak value of used storage in the Usage statistics page.

Limiting subtenant request rate

Platform administrators can limit the request rate of each subtenant via the following custom properties:

It is also possible to customize the buffer size for the CEP queue and the data broker queue for a particular tenant. This can be done from the management tenant by using the following subtenant custom fragments:

When there is no limit on tenant and system level, the limit feature is considered as disabled and the tenant gains unlimited access. To switch off request rate limiting after it was enabled, set the value to “-1”.

Tenant policies

A tenant policy is a set of tenant options and retention rules. Tenant options and retention rules may be specified during tenant creation.

Assign tenant policy

Creating a tenant policy with a specific set of options and rules saves time when creating multiple tenants with the same settings.

Info: The options and rules are copied into the tenant. Editing the policy has no effect on tenants that have already been created.

To view tenant policies

Click Tenant policies in the Tenants menu to view all available tenant policies.

Tenant policies

For each tenant policy, the name, an optional description and the number of options and retention rules is provided, either in a list or a grid.

To create a tenant policy

  1. Click Add tenant policy in the top menu bar.
    Add new policy
  2. In the resulting dialog box, enter a name and an optional description.
  3. Add at least one retention rule. For details on creating retention rules, see Administration > Managing data retention > Retention rules.
  4. Optionally, add a tenant option.
  5. Click Save.

The tenant policy will be added to the tenant policies list.

Important: When defining the retention rules and options you can select a checkbox to allow subtenants to modify definitions of these rules or options. By default, this checkbox is not activated. Be aware that if you do not select this checkbox after creating the subtenant you need to run an update from the management tenant in order to edit those rules and options.

To edit a tenant policy

Click the respective policy entry or click the menu icon at the right of the policy entry and then click Edit.

In the resulting dialog box, make your edits and click Save to save your settings.

To delete a retention rule or a tenant option from a policy, hover over it and click the delete icon.

To duplicate a tenant policy

Click the menu icon in the tenant policy entry you want to duplicate and then click Duplicate.

To delete a tenant policy

Click the menu icon in the tenant policy entry you want to delete and then click Delete.

Managing user hierarchies

With user hierarchies you can reflect independent organizational entities in Cumulocity IoT that still share the same database. These entities can have limited permissions to subsets of the shared data and can manage their own sub-users.

Info: To be able to use this feature, your tenant must be subscribed to the application “feature-user-hierachy”.

Viewing user hierarchies

In the Users page, user hierarchies are indicated by an arrow left from the user icon. Clicking on the arrow unfolds the user hierarchy. You can also fold and unfold the entire user hierarchy using the Expand all and Collapse all links at the right of the top menu bar.

A small number next to the user name shows how many direct sub-users a user has. Sub-users are users that can be managed by their respective parent user and that have at most the permissions of that parent user. In the example below, the user “Demo user” has one direct sub-user.

User hierarchies

To create a sub-user

User hierarchies are created by assigning an “owner” to a user. The owner can manage the user. The user can have at most the same permissions as the owner.

  1. Select the user in the Users page.
  2. In the Owner field, select the user you want to assign as owner from the dropdown list.
  3. Click Done to confirm.

Select owner

Info: When creating a new user, the owner is automatically set to the user who is logged in if the logged-in user has only “User management” CREATE permission. The owner can be changed later, but only by a user with “User management” ADMIN permission.

If you want an owner to manage only their sub-users, make sure that the owner does not have a global role with “User management” permission for all users.


A user A has the role “business”. User A becomes the owner of a new user B. User B can then only get a business role assigned (and not for example an admin role) as the user cannot have higher permissions than the owner.

Owner Sample

Delegating user hierarchies to other users

In Cumulocity IoT, users can delegate their user hierarchies and permissions to another user. The delegated user then has the same user management permissions as the user who activated the delegation.

You may of course also delegate on a temporary basis, for example if you are temporarily unavailable.

To delegate permissions to a user

Either open the user and click the delegate icon in the Delegated by field, or click the menu icon at the right of the user entry in the user list and from the context menu, select Delegate.

User delegation

To undelegate permissions

Remove the delegation in the Delegate by field, or click the menu icon at the right of the user entry in the user list and from the context menu, select Undelegate.

If the delegated user also needs to manage specific devices, the admin user must assign this device permissions (inventory roles) directly to the intended user. This can be done by using Copy inventory roles from another user. For details refer to Administration > Managing permissions > Assigning inventory roles to users.

Info: Delegation works only inside user management and does not have any implication to other places.

Troubleshooting sub-users

In the example below the user cannot change the access to the Administration application, because the owner of the user has no “User management” permission. As a result, the owner user can not assign built-in applications (and the owned user cannot use them).

Warning message

Customizing your platform

With the Enterprise tenant of Cumulocity IoT, you can customize your platform in various aspects and according to your requirements.

Apart from various configuration settings, you can use your individual branding and your individual domain name.

Click Enterprise tenant in the Settings menu to access these settings.

Custom settings


Info: In some of the properties you can configure email templates for various purposes. Be aware that the corresponding emails are send with “text/html” as content type.

The following placeholders can be found in the Configuration tab:

Placeholder Description
{host} The value of this placeholder is “https://” + “<<tenantId>>” + “<<base-domain>>”. For example, if “tenantId” is auto-generated, the host will be https://t12345678.cumulocity.com.
{tenant-domain} This is the location in which a tenant can be accessed. It is equal to “https://” + “<<tenantDomainName>>”. For example, {tenant-domain} can be https://myTenant.cumulocity.com. In case of an Enterprise tenant, the {tenantDomain} placeholders can have different values. An example tenant domain is https://myTenant.myhost.com.
{token} An automatically generated system token for password reset purposes. When a user requests a password reset, a new random token will be generated. This token will be associated only with the particular user and will allow for a single password reset action. The standard way of using this placeholder is along with the {tenant-domain} property as “{tenant-domain}?token={token}”.

Two-factor authentication

Under Two-factor authentication, you can change the SMS template which is sent to the users.

TFA configuration

In the Support link section, you can enter a URL to be used to link to a support page. If you do not provide a link here, the default link to the Software AG TechCommunity page will be used.

Cookie banner

In the Cookie banner section you specify the settings for the banner with the cookie usage information. The banner is shown for all users of the current tenant and subtenants until a user clicks Agree and proceed.

The following parameters can be specified:

Domain name

A key feature of the Enterprise tenant is the ability to operate the Cumulocity IoT platform using a custom domain name. This means that you can configure the platform to serve you and your customers using a host name of choice, for example *.iot.mycompany.com rather than the default URL of Cumulocity IoT. In addition you’ll be able to create subtenants using your domain. These will be using <subtenantName>.iot.mycompany.com as their host names.

Info: The custom domain name functionality is only available for Cumulocity IoT cloud installations or On-Premise installations which don’t use a custom load balancer.

There are three prerequisites for using a custom domain:

  1. To activate your domain, a valid license that covers your wildcard domain is required. Please contact product support to install a license for your domain.
  2. You’ve obtained a valid wildcard SSL certificate for your IoT domain, for example a certificate for *.iot.mycompany.com.
  3. There is a valid DNS configuration for your domain which ensures that all requests to *.iot.mycompany.com are routed to Cumulocity IoT. (see below).

SSL certificate requirements

The following criteria have to be met by any SSL certificate to be used with the Enterprise tenant feature:

Cumulocity IoT supports a single certificate that is signed by the root CA, as well as a full chain certificate which contains one or more intermediate certificates.

Packaging the SSL certificate in PKCS #12

In order to use a SSL certificate with Cumulocity IoT, the certificate together with its private key have to be uploaded to the platform in a single file, using the PKCS #12 file format.

Most certificate authorities deliver their certificates and corresponding private keys in the PEM file format, using two separate text files for the certificate chain and the private key. Make sure that the private key is not protected with a password/passphrase.

Such PEM files can easily be repackaged into #PKCS #12 using OpenSSL. In the following example, OpenSSL is used to combine a certificate chain (chain.cert) and the corresponding key (privkey.pem) into a PKCS #12 keystore file (out_keystore.p12) that can be used with Cumulocity IoT.

openssl pkcs12 -export -out out_keystore.p12 -inkey privkey.pem -in cert.pem -certfile chain.pem

DNS requirements for enterprise domains

The DNS entries for your custom domain have to be configured in a way that all requests are routed to the Cumulocity IoT platform.

We strongly recommend you to use a wildcard CNAME entry for this purpose. The CNAME needs to contain your wildcard domain from the certificate in the NAME field. The VALUE field of the CNAME entry has to point to the hostname of Cumulocity IoT. This target hostname can be easily determined by looking at your current tenant URL. If your tenant URL is http://mytenant.cumulocity.com, the target hostname is cumulocity.com. Please also make sure to delete any conflicting A entries.


If you want to use *.iot.mycompany.com for your enterprise subtenants and if you’re using the Cumululocity IoT at cumulocity.com, the following CNAME entry has to be added to your DNS zone:

NAME                  TYPE   VALUE
*.iot.mycompany.com.   CNAME  cumulocity.com.

We highly discourage any use of alternative DNS configurations for the following reasons:

Uploading the certificate and activating your domain

Once the DNS configuration is in place and if a certificate with the given requirements is available, it can be easily uploaded to the platform.

Domain name

Afterwards, you can activate the domain with a single click. After the domain has been activated, you will be redirected to your enterprise tenant using the new domain name. You will also receive an email with information about the activation. Note that your management tenant domain name is static, for example, if your wildcard domain is “* .iot.mycompany.com” then your management tenant domain will be “management.iot.mycompany.com”.

Info: After the activation is completed you will no longer be able to access your tenant with the Cumulocity IoT domain name. Instead, use your custom domain name.

Updating your certificate

When your certificate expires, you must update your certificate with a new one with an extended validation period. When updating a certificate, you need to make sure that

Info: Keep in mind that after replacing the certificate it may take some minutes until the new certificate has been delivered to the users/browsers.

Deactivating your certificate

If you wish to return to your old domain at Cumulocity IoT, you can simply deactivate you certificate.

Important: Use with care. Your customers will not be able to access their subtenants anymore.


In case you cannot reach Cumulocity IoT using your custom domain, we recommend you to perform the following checks to verify your DNS setup.

Check if the DNS entry is correct

Execute the following command:

host management.<your domain name>

The following result should be returned:

management.<your domain name> is an alias for <instance domain name>
<instance domain name> has address <ip address>

Check if the API is responding

Execute the following command:

curl -v -u '<tenant ID>/<your user>:<your password>' --head http://management.<your domain name>/inventory/managedObjects

The following result should be returned:

HTTP/1.1 200 OK

Info: Keep in mind that after changing the DNS entry it might take up to 24 hours until the new entry has been propagated.

Support user access

The support user access feature enables Cumulocity IoT platform providers (Software AG in case of the public cloud instances or service providers with on-premise installations) to support their customers by accessing their users using a support user. A support user is a user in the Management tenant that has specific permissions, i.e. to access subtenant users in case of any issues.

To use this feature, support user access must be configured and the required support users must be created in the Management tenant, see Administration > Platform configuration settings > Support user.

Info: On the Cumulocity IoT public cloud instances, the support user functionality can only be used by the Software AG Global Support team for providing customer support. It is not available for Enterprise tenant customers to support their customers/subtenants.

Configuring support user access

Support user access can either be

This is configured globally in the Management tenant, see Administration > Platform configuration settings > Support user.

If activated globally, the support user can log in to all allowed subtenants as any user without restriction.

If deactivated globally, support user access can still be enabled by a subtenant user if required. This is done by clicking Enable support in the User menu, see Getting started > User options and settings. The support access is not restricted to the user who activated it but applies to all users of the tenant. This is necessary for retracing of role/right issues.

After a user has activated support access, the menu item changes to Disable support, so that the user can disable a pending support request which has been resolved actively before it expires.

Info: If you don’t see either the Enable support or Disable support button in the User menu, support user access has been activated globally. Contact product support for more details.

Info: If a user with tenant management admin permissions disables the support request, all support requests for the tenant will be disabled.

The duration of the active support request can be globally configured in the Management tenant (default is 24 hours), see Administration > Changing setting > Configuration settings.

Each new support request will prolong the support duration for the specified number of hours. After the last support request in a subtenant has expired or has been actively disabled by the user, the support user access for the subtenant will immediately be disabled (if not activated globally).

Details on the status of support requests and support user access for a tenant can be found in the Properties tab of the tenant, see Managing tenants.

To log in as support user

To log in as support user from the Management tenant, you must provide the following information in the Login screen:

“Support user” and “user” are entered into the Username field in the following notation:

<support user>$<user>


Suppose you get a support call from a user “John” in the tenant testtenant.cumulocity.com (which has the tenant ID t07007007). Your username in the management tenant is “Jill” and you are permitted to carry out support for testtenant.cumulocity.com. In this case, you can log in with the following credentials to reproduce what John is seeing:

Support user access login

Alternatively, enter “<support user>$” into the Username field to access the tenant with one of the administrative users.

Audit logs are created for each support user access and for the actions that support users perform. In the column “Who?” the author’s name will be shown in the form of “support_user$user”.

Using the data broker

Data broker lets you share data selectively with other tenants. You can share:

Navigate to Data connectors in the Data broker menu if you would like to send data to another tenant. Navigate to Data subscriptions, if you would like to receive data from another tenant.

Data broker menus

Important: Devices that are forwarded using the data broker are charged like normal devices in the destination tenant.

Be aware of the following limitations of the data broker:

Data connectors

A data connector describes the subset of the data that you would like to send to a destination tenant as well as the URL of that destination tenant.

Viewing data connectors

Click Data connectors in the navigator to see a list of all currently defined data connectors with their status.

Data broker connectors list

For each data connector, the following information is provided:

Use the toggle to enable and disable data forwarding to the destination tenant. If data is being forwarded, the toggle reads “Active”. If data is not being forwarded, the toggle reads “Suspended” or “Pending”. “Suspended” means that you have disabled forwarding. “Pending” means that the destination tenant has disabled forwarding.

Info: If the source tenant has been suspended all its data broker connectors will be suspended as well.

To add a data connector

  1. Click Add data connector in the top menu bar.

  2. In the Settings tab, provide the following information to create a new data connector:

    Field Description
    Title The name of the data connector.
    Target URL for data connector The URL of the tenant to which data will be forwarded. Once saved, you cannot edit this value anymore.
    Description A textual description of the configuration. Both the name and the description will be visible on the destination side after accepting the subscription.
    Data filters A set of filters that define what is copied to the destination. You need to configure at least one filter.
  3. Click Add filter to configure a new filter.

    Data broker configure filter

  4. Each data filter contains the following information:

    Field Description
    Group or device The group or device that is forwarded. If you select a group here all sub-groups and sub-devices of this group will be forwarded. See the warning below on the usage of All objects.
    API The type of data being forwarded (alarms, events, measurements, manages objects) or being received (operations).
    Fragments to filter The fragments that need to be present in a device to be forwarded.
    Fragments to copy The fragments that are copied to the destination. If nothing is specified here, only standard properties of managed objects, alarms, events and measurements are forwarded (see below). Select Copy all fragments to forward the entire object.
    Type filter Forwarded data needs to have this value in its "type" property.
    1. Click Save to save the configuration.

    Warning on the usage of All objects

    The option All Objects is left in the UI to ensure backward compatibility with older versions. We intend to deprecate it and we strongly recommend to not use this option.

    When selected, Cumulocity IoT will synchronize all types of objects, system as well as user-defined, and might override, or create out of context, objects in the destination tenant. Such objects may contain references to other objects and also configuration information. It is the user’s responsibility to check and ensure consistency of such information in the transferred objects in the target environment.

    This concerns items such as SmartREST templates, device protocols, smart rule configurations and dashboards.

    For example, when you create a smart rule on the source tenant and you synchronize all objects, then the data broker creates a smart rule managed object on the destination tenant. The rule itself is not copied, because a synchronized smart rule would perform the same action on the same device for the same configuration. That would create duplicate emails for the same recipients when an alarm occurs.

    If the Group or device field is filled in, the entire descendant structure of the inventory is forwarded to the destination as soon as the connector stays active. if the Group or device field is empty or set to “all” the descendant structure of the inventory is not forwarded; in this case the filter works in “lazy” mode, i.e. forwards the device or asset along with its first event/measurement/alarm.

    If operation API is checked in filters, operations created in the target tenant will be forwarded to the source tenant. This applies only to operations that meet the following conditions:

    • operation’s device itself is a result of forwarding data;
    • operation matches other filter criteria.

    Updates of the operation status coming from the source tenant will be forwarded to the destination tenant.

    The heading of a data filter summarizes the configuration in one line. The standard properties that are copied by default are:

    • For created alarms: type, text, time, severity, status
    • For updated alarms: status, text, severity
    • For created events: type, text, time
    • For created measurements: type, text, time
    • For created and updated devices: type, name, c8y_IsBinary, c8y_IsDeviceGroup, c8y_IsDevice, c8y_DeviceGroup, c8y_DeviceSubgroup, c8y_SmartRule, c8y_DynamicGroup, c8y_DeviceQueryString
    • For updated operations: status

    After saving the configuration, you will see a security code displayed below your configuration. The security code prevents unintended forwarding of data. You need to communicate this security key separately to an administrative user of the destination tenant. You can click the copy icon next to the security code to copy the code to your clipboard.

    Security code

    To edit a data connector

    Click the menu icon at the right of a data connector entry and then click Edit.

    In the Settings tab, edit the data connector configuration.

    See To add a data connector for details on the settings.

    To duplicate a data connector

    Click the menu icon at the right of a data connector entry and then click Duplicate to create another data connector with the same configuration.

    To delete a data connector

    Click the menu icon at the right of a data connector entry and then click Delete to stop data forwarding and delete the data connector.

    To view alarms for a data connector

    Open a data connector and switch to the Alarms tab to display current alarms for the data connector.

    For details on data broker alarms, see Troubleshooting below.

    For details on alarms in general, see Device Management > Monitoring and controlling devices > Working with alarms.

    Data subscriptions

    In the Data subscriptions page, you can manage existing data subscriptions or create new ones.

    Click Data subscriptions to see a list of all currently defined data forwarded to your tenant.

    Data subscriptions

    For each subscription, the name, the target tenant and the status (enabled or disabled) is provided on a card.

    Use the toggle to temporarily stop forwarding data into your tenant.

    To set up data forwarding on the receiving end

    1. Click Add data subscription in the top menu bar to receive data.
    2. In the new card, enter the security code that you received from the sending end of the data.
    3. When the connection is established, click Accept to start forwarding data into your tenant. The subscription is active now.
    4. You can use the toggle in the card to temporarily stop forwarding data into your tenant.

    You can now navigate to the Device Management application or the Cockpit application. You will find a new “virtual group” with a specific icon (see the screenshot below) showing the forwarded devices. The group will have the same name as your subscription. Devices are “lazily” created on the destination side whenever they send data for the first time after setting up an active subscription.

    To delete a data connector

    Click the menu icon and then click Delete to stop data forwarding and delete the data connector.


    If the data broker is not able to connect to a destination tenant, a CRITICAL alarm is raised, showing the connector which is affected.

    Queue overflow

    On the source tenant, data broker queues data that cannot be forwarded immediately to the destination tenant. The amount of data that can be queued is limited. If Cumulocity IoT cannot queue any further data, the oldest queued data is dropped. In this case, a MAJOR alarm is raised in the tenant, showing the connector which is affected.

    Data broker alarms

    Similarly, an alarm is raised when the input queue is overflown.

    To reduce the number of alarms, alarms are not triggered more often than once per minute.

Storage quota

The storage quota is in place for a tenant when a storage quota per device is set by the platform administrator. The total storage available to the user is calculated using the formula storage quota per device x number of devices. A check is performed every night to ensure the quota is not exceeded.

In case the quota is exceeded, an email is sent to all tenant administrators to warn them that data will be deleted the following night. After 24h, if the quota is still exceeded, all data retention limits are reduced by a fixed percentage. The storage quota per device will be reduced as a result of this rule.

Info: The storage quota feature needs to be defined on the tenant and cannot be enabled/disabled by configuration.


Let us assume that a tenant has a storage quota of 10 GB. Retention rules are 80 days for measurements, 90 days for all other data.

The total storage is now at 9.8 GB.

Managing storage quota warning email

This feature is only visible if a storage quota was set for the tenant.

The tenant administrators can set a user group (global role) and threshold for an email to be sent once a day if the storage used is higher than a particular percentage of the storage quota. The default setup is sending an email to the “admin” role when the storage reaches 80% of maximum storage.

The email warning can also be disabled.

License management

The management tenant may manage the licenses for the domains of the enterprise tenants via the UI.

License management

To add and validate a domain license

  1. Log into the management tenant.
  2. Navigate to the License management page under the Settings menu. In the License management page all domain licenses are listed, together with their status (green checkmark = valid).
  3. Paste the license key into the Add tenant license field and click Add.

The license will be validated and added to the tenants options.

To delete a domain license

  1. Log into the management tenant.
  2. Navigate to the License management page under the Settings menu.
  3. Click the menu icon at the right if the domain for which you want to delete the license and then click Delete.

Usage statistics and billing

Viewing usage statistics

The Usage statistics page provides statistical information on each subtenant.

Moreover custom properties are displayed, if configured.

Custom properties may be defined in the Properties Library and then set their values in the Custom properties tab of the tenant.

You can filter the usage statistics list for a time period by adding the start and end date in the top menu bar and click Filter. The Usage statistics page will show the numbers for all subtenants for this time period.

Info: If a tenant was created after the selected time period, it will show up but the numbers are “0”.

You can also filter and sort the list on any column by clicking the filter icon next to the column name and providing the filtering criteria. See also Getting Started > UI functionalities and features > Filtering.

Important: The date/time range used here might differ from your server time due to different time zones.

To export the usage statistics table

  1. Click Export CSV at the right of the top menu bar to export the current view of the statistics table to a CSV file.
  2. In the resulting dialog box you can customize the CSV output by specifying a field separator, decimal separator and charset.

  3. Click Download to start the export.

The CSV file will be downloaded to your file system.

Microservice usage

The microservice usage feature gathers information on the resource usage per subtenant for each microservice. This enables Enterprise Tenants and service providers to charge tenants not only based on subscriptions but also based on resources usage.

Billing modes

Cumulocity IoT offers two billing modes:

The billing modes are specified per microservice in the microservice manifest and are set in the field “billingMode”.

RESOURCES: Sets the billing mode to resources-based. This is the default mode and will be applied to all microservices that are not explicitly switched to subscription-based billing mode.

SUBSCRIPTION: Sets the billing mode to subscription-based.

Isolation level

Two isolation levels are distinguished for microservices: per-tenant isolation and multi-tenant isolation.

In case of subscription-based billing, the entire resources usage is always assigned to the microservice owner, independent of the isolation level, while the subscribed tenant will be billed for the subscription.

In case of resources-based billing, charging depends on the isolation level:

In case of multi-tenant isolation level, the owner of a microservice (e.g. the management tenant of an Enterprise Tenant or service provider) is charged for the used resources of the subtenants. The subtenants should be charged based on the subscription according to the agreement between the microservice owner and the subscribed tenant. The list of subscribed applications is available as part of the tenant usage statistics record as subscribedApplications.

Resources usage assignment for billing mode and isolation level

Billing mode Microservice Isolation Resources usage assigned to
Subscription-based Per-tenant Owner
Subscription-based Multi-tenant Owner
Resources-based Per-tenant Subscriber
Resources-based Multi-tenant Owner

Collected values

The following values are collected on a daily base for each tenant:

Microservice resources are counted based at limits defined in the microservice manifest per day. At the end of each day, the information about resource usage is collected into the tenant statistics. It is also considered that a microservice might not be subscribed for a whole day.

Example: If a tenant was subscribed to a microservice for 12h and the microservice has 4 CPU and 4 GB of memory it should be counted as 2000 CPU milliseconds and 2048 MB of memory.

For billing purposes, in addition to CPU usage and memory usage the cause for the billing is collected (e.g. owner, subscription for tenant):

  "name": "cep",
	"cpu": 6000,
	"memory": "20000",
	"cause": "Owner"
  "name": "cep-small",
  "cpu": 1000,
  "memory": "2000",
  "cause": "Subscription for tenant"

The information on the microservice usage is presented in the Usage Statistics page.

Tenant statistics

For more details, refer to Tenants > Tenant usage statistics in the Reference guide. Note that details are available only for daily usage. For a summary query only the sum of all issued requests is returned.


Auto-scaling monitors your microservices and automatically adjusts capacity to maintain steady, predictable performance at the lowest possible cost. It is easy to configure the microservice scaling by setting the property scale in the Microservice manifest.

For instance, when you have a microservice with scale policy set to AUTO and the CPU usage points that it is needed to start a new microservice instance for three hours, the billing logs: (24/24 + 3/24) * consumed resources.

24/24 - one instance active for the whole day
3/24 - second instance active only three hours

Note that an audit record is created for every change of the number of instances.

Audit logs

For more information, refer to Auditing in the Reference guide.

Timezone handling

Important: Cumulocity IoT platform servers by default work at UTC timezone. Other time zones are also supported by the platform and can be selected by the service provider at installation time. Thus, the general metering functionality is also guaranteed for non-UTC server time zones.

The tenant usage statistics are collected on a daily base according to the beginning of day (BOD) and the end of day (EOD), which are defined by the server timezone. As a result, if the local time zone of a user is different from the server timezone, an operation triggered by the user may be assigned to a different day according to the server time.


Request counting - Example 1
Device Server
Time zone CEST +2h UTC
Send measurement time 26.08.2020T01:30:00+02:00 25.08.2020T23:30:00Z


The request will be billed to the day 25.08.2020 as this is the server time of the request handing.

Request counting - Example 2
Device Server
Time zone UTC UTC
Send measurement time 26.08.2020T01:30:00Z 26.08.2020T01:30:00Z


The request will be billed to the day 26.08.2020 as the server time is the same as the device time.

Microservice resource billing - Example 1
User Server
Time zone CEST +2h UTC
Subscribe time 26.08.2020T12:00:00+02:00 26.08.2020T10:00:00Z
Unsubscribe time 27.08.2020T12:00:00+02:00 27.08.2020T10:00:00Z


The resources will be assigned mainly to the day 26.08.2020 as according to the UTC time zone the microservice was active for 14 hours that day and for 10 hours the next day. This might be a bit different from what a user expects as from his perspective the microservice was active for 12 hours each day.

Microservice resource billing - Example 2
User Server
Time zone KI +14h (Kiribati Islands) UTC
Subscribe time 26.08.2020T12:00:00+14:00 25.08.2020T22:00:00Z
Unsubscribe time 26.08.2020T20:00:00+14:00 26.08.2020T06:00:00Z


From the user perspective the microservice was subscribed for 8 hours at 26.08.2020 but at server time it was 2 hours before EOD of 25.08.2020 and 6 hours after BOD at 26.08.2020.

Microservice resource billing - Example 3
User Server
Time zone CEST AS -11h (American Samoa)
Subscribe time 26.08.2020T12:30:00+2:00 25.08.2020T23:30:00Z
Unsubscribe time 26.08.2020T13:00:00+2:00 25.08.2020T24:00:00Z


In this case we have a big time shift between the server and the user time. All resources will be billed to the day 25.08.2020 according to the server time.

Daily routine

Usage statistics consist of values that are progressive like the request count and values that are snapshots of a state at a given time period. In case of the second type of data, values are refreshed several times each day but the value from EOD is the value that is assigned for the given day.

Value type Refreshed
Request count flush Every 5 minutes
Used storage 9, 17 and EOD
Device count 9, 17 and EOD
Subscribed applications 9, 17 and EOD
Microservice resources 9, 17 and EOD



A Cumulocity IoT platform tenant can have several states:


Any extension deployed to the platform as a microservice is billed as “used” and the billing starts according to the begin of usage. After the application is subscribed to the tenant a process of application startup is triggered which will go through several high level phases:

A tenant that is billed for resources can view the point in time when the microservices billing has been changed in the audit logs. The audit log entries, for example “Scaling application ‘…’ from X to Y instances” contain the information about the changes of instances and resources consumed by the microservice.

Tenants should also be able to see the full application lifecyle in the application details. In the Status tab, you can see an Events section that is showing very low level stages of the application startup. Some of the most important are:

Info: There is no event in the Events section when the microservice has reached the state “Ready” as this happens according to the readiness probe.

Audit logs and events are stored at tenant space according to the isolation level. For multi-tenant isolated microservices this is the tenant that is the owner of the microservice and in case of per-tenant isolation level it is the subscribed tenant.

Billing pricing models

The Cumulocity IoT platform collects a lot of different usage statistics data which is used for billing customers.
