Which statement describe the function of the perfmonCollectCounterData operation used in the Cisco Unified Communications Manager Serviceability Perfmon API?

Question

Options

• AIt returns the Perfmon data for all counters that belong to an object on a particular host.
• BIt collects files from RTMT.
• CIt collects the Perfmon data for all counters that have been added with perfmonAddCounter to the session handle returned from perfmonOpenSession.
• DIt returns the list of available Perfmon objects and counters on a particular host.

• A
  95% (39)
• B
  2% (1)
• C
  2% (1)

Explanation

perfmonCollectCounterData is a stateless, host-targeted operation - it queries a specific host and returns Perfmon data for all counters belonging to a given object, which is exactly what option A describes. No prior session setup is required.

Why the distractors are wrong:

• C describes perfmonCollectSessionData, a different operation that works against a session handle pre-populated via perfmonAddCounter - a common mix-up since the names are similar.
• D describes perfmonListCounter or perfmonListObject, which enumerate available objects/counters rather than retrieving live data.
• B is a fabricated distractor; the Perfmon API has nothing to do with collecting files from RTMT.

Memory tip: Think of perfmonCollect**Counter**Data as "give me everything for this object on this host, right now" - it's broad and direct, no session needed. When you see "session handle" in an answer, that's a signal pointing to perfmonCollectSessionData instead.
