RE: squid and mrtg.

Dear All:
        We also got the same problem. I also try the newest version of MRTG
( 2.8.11) but still have the same error message.
        And I don't know how to make MRTG to translate name -> OID .
          I also get the Sixth draft squid MIB from
http://www.ircache.net/Cache/cache-snmp/ , but I don't know how to parser
that MIB file.

        It is correct enough.

        I do not believe that 'cfgmaker' works with squid. It is a router
based tool.

        It is because that patch is old, very old in fact. It is for very
early versions of MRTG.

The configuration file that you found is a good starting point. The error
that you recieved is caused because MRTG can not translate that name to a
OID. If you use the MRTG included MIB parser, that will read the Squid MIB
and then allow MRTG to do a name -> OID conversion and therefore work.
