1. Want to know how CAPC is licensed ?
2. If so, how to find out that number ?
Release : 19.1
Component : PERFORMANCE MANAGEMENT INTEGRATIONS
Can check Administration->Data Sources->System Status.
Q) Can these be extracted using a SQL query or programmatically somehow?
Ans) Nope, everything in there is a service running storing results in PC memory that the page queries. The info displayed is based on last 1 min rest calls/etc for the datasource, DB, file, etc that is checked.
(No rest call to these services to get that info.)
