You can find some concrete examples in
Using curl commands for setting various tenant options. However, you can use any tool you like.
To change the tenant options, you need ADMIN permission for "Option management" in
Cumulocity IoT. See the information on the Administration application in the
User guide at
https://www.cumulocity.com/guides/ for details on managing permissions.
CAUTION:
After you have changed a tenant option using a REST request, the correlator will automatically restart. An alarm with a MAJOR severity will be created in this case; you can view it on the
Alarms page of the Cockpit application (see the
User guide at
https://www.cumulocity.com/guides/ for information on how to work with alarms).
