Re: [squid-users] SNMP for Squid

Here's a page I found helpful.

http://www.squid-cache.org/SNMP/

Remember to load the mibs into mrtg, this should go in your mrtg
configuration.

LoadMIBs: /etc/squid/mib.txt

The mib can be in any arbitrary location depending upon platform, or it
might not even be there if the box doesn't actually run squid. Download
squid if you need a copy of the mib.

Read the configuration help at http://www.mrtg.org for further
information.

Of course you should insure that squid is configured to allow snmp
queries, with the snmppublic acl, and that you allow access

acl TEST src 192.168.1.1/255.255.255.0
acl snmppublic snmp_community public
snmp_access allow snmppublic TEST
