Thanks Amos!
But now I'm facing another problem while trying to monitor the
percentage use of the CPU with the 1.3.6.1.4.1.3495.1.3.1.5.0 OID.
While polling (v1 or v2), it keeps returning only the value "1" (each
instance).
As I saw on the wiki http://wiki.squid-cache.org/Features/Snmp, this OID
is for squid version 2.2+, and I'm currently experimenting with version
3.2.0.4.
Is this related to the version, or am I doing something wrong?
snmpwalk -c community -v 1 localhost:3401 1.3.6.1.4.1.3495.1.3.1.5.0
SNMPv2-SMI::enterprises.3495.1.3.1.5.0 = INTEGER: 1

Could be a few things.
* the docs may be broken (unlikely). Try without the trailing .0 to
see if that looks right.
I tried without .0 but no diference.
It's a percentage value being cast to an INTEGER for SNMP. So...
* it may be that you are only using 1% or 100% of a CPU by Squid.
Check this against other software displaying the machines CPU.
I was doing some benchmarking, so I tried with "top" and the value was
around 15-20 % per instance.
* the casting may be broken and rounding a large decimal up.

Anyway I'll solve this with some shell scripts.
