Re: [squid-users] mrtg and squid

I was trying to reference the OID numerically because when I refence it by
name I get messages like "evaluated to 5 instead of a number"

File output and mrtg output below.

cat /var/www/mrtg/squid/mrtg.cache.cfg

Your Target does not at all match what is in the documentation.

The numeric OID you have specified does not exists as a value in the Squid
MIB, and the error message is thus fully correct as MRTG can not plot
things that does not exists.

.1.3.6.1.4.1.3495.1.1.1 is enterprise.nlanr.Squid.cacheSystem.

Why do you specify the OID numerically? It is much easier to load the
Squid MIB into MRTG and then specify the OID by name.

Henrik
