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

How I know something. In the light of dozens of different operating 
systems. Check the source code, they are also open. Even the top is not 
too reliably shows the load across multiple cores. By the way, SQUID, 
except in very specific configurations, running on a single core.

Thanks for that. But do you know the CPU usage shown in the cache 
manager is 24% of the total 4 CPU cores? If it says 100% does that 
mean that all 4 cores are fully utilized?

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.

Thanks for that. But do you know the CPU usage shown in the cache manager
is 24% of the total 4 CPU cores? If it says 100% does that mean that all 4
cores are fully utilized?
