We have metrics on services created and exposed through portal however do we have similar options for CA API Gateway services (Note: service that are not exposed through portal).
There is not assertion to do this out of the box, but there is a customer assertion called Gateway Metrics Assertion that provides access to Gateway metrics via policy.
If that is something you are looking for please open a support issue and one of the engineers can get you the approval for the customer assertion.
Hope this help
So the Gateway metrics assertion mentioned by Abs is only available in certain versions of the Gateway. This assertion simply lets you query and return in xml format in policy the same basic details you see in the Services Dashboard in Policy Manager -> view -> dashboard. .Where the service_metrics table of mysql is graphically displayed.
This information can also be obtained via snmp within the default SNMP mib. Or using the TACTICAL SNMP assertion.
But this is not the same information that would be stored on the portal.
So the only service details available on the Gateway is the same basic data in the policy manager dashboard.
