Finesse doesn’t keep counts of connected users to the individual Finesse nodes, because generally we use a stateless model. The best we have is a count of the logged in Users to the Finesse pair. This can be accessed using the Diagnostic Portal API:https://developer.cisco.com/docs/finesse/#!diagnostic-portal-apis
Sorry I don’t have a better answer.
Thanks,
