We are currently looking into CUCM to identify what limitations we would have in polling via the perfmon API.
In the CUCM documentation for 9.X(http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/devguide/9_1_1/xmldev-911/serviceability.html#wp1059283), we see limitations in the form of
-Allowed Performance Queries Per Minute
-Allowed Device Queries Per Minute
-Maximum Performance Counters Per Session
In the Cisco devnet site, which was released roughly around version 10, we don't see any listing of limitations in regards to limitations / best practices like we see in the documentation listed for 9.X. are these enterprise parameters still the limitations?
Furthermore, In CUCM we do not see a parameter for max number of sessions allowed for performance polling. is there any limitation for this or not?
Any additional information would be great. Thanks!
I tested the Maximum Performance Counters Per Session parameter in my lab. I used a script that was developed to gather every instance of every counter and return their values. Here is what I see:
cat output_8X.txt | grep 'CStatus' | wc -l
cat output_9X.txt | grep 'CStatus' | wc -l
cat output_10X.txt | grep 'CStatus' | wc -l
It seems that this parameter is a soft limitation, but I am still unsure. Any ideas?
