CSM's have a limitation where the control processor can only manage 200 current health checks at one time. This problem arises if you have a number of serverfarms and a probe with short intervals like 2 seconds, if the 200 limit is reached which has happened, the health checking can be delayed to say 40-60 seconds instead of 2 seconds configured, because the 200 limit has been reached the control processor is unable to cope.
Question: I would like to run a TCL script for say 24 hours. Running command (sh mod csm x tech probe) say every 30 seconds to see the “low and high†open sockets in system during this period. I'm new TCL any ideas?
'Open Sockets in System' below : 180 / 240 - shows you are using 180 concurrent TCP health checks out of 200 available (not 240), confirmed this with Cisco
sh mod csm 3 tech probe
