Environment

Aria Operations for Networks

vRealize Network Insight

Cause

The maximum number of applications from ServiceNow/CMDB per datasource in Aria Operations for Networks is 5000, and this limit is hardcoded.

Refer to the following document for the CMDB/ServiceNow Max configuration details: Supported CMDBs 

Resolution

As a workaround, we can filter ServiceNow applications in the SNOW dashboard, then use the same filter string to modify the .json file in Aria Operations for Networks (AON) to display only the required applications. After modifying the .json file, import it into AON.

For further assistance, open a Broadcom support case. For more information, see Creating and managing Broadcom support cases.
