[squid-users] Squid CPU usage in cachemgr.cgi

[Faheem]

Hello,

I am trying to setup proper monitoring for our squid farm so that we will
be alerted when there is a performance issue. I was looking at several
statistics of squid available in cachemgr.cgi and see the below. I am a bit
confused about the CPU usage stats shown in the cachemanager. If I go to 5
Minute Average of Counters in cachemanager it says "cpu_usage = 24.008036%"

What does this actually mean? Is this inclusive of all 4 cores in my
server? We have CPU affinity set for squid process and it uses all 4
available cores. So does 100% mean that all 4 cores are fully being
utilized? Which parameter would be the best one to look at to understand
the real CPU usage.


Thanks,
meeh.
