<p>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.<br>

<div dir="ltr">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?<br>

<div>Hello,<br>
<br>
</div>
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%"<br>
<br>
</div>
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.<br>
<br>

Thanks,<br>
