[mrtg] MRTG not honouring mib file

[Babu C]

Sorry I think I received the unmodified SNMP_util.pm I suppose as I 
couldnt find the changes in the file I received. Could you verify this 
and send me the modified SNMP_util file?
Regarding LoadMIBs, I have only one statement in the mrtg.cfg file and 
its loading only one mib file

Thanx & regards
Babs

I added three print statements to the "snmpMIB_to_OID" function in 
SNMP_util.pm.

On line 1197, change

 print "snmpMIB_to_OID: opening $arg\n" if ($arg =~ /squid/i);

to

 print "snmpMIB_to_OID: opening $arg\n";



and copy the new version to the

 /usr/local/lib/perl5/site_perl/5.10.1/SNMP_util.pm

 /usr/ports/net-mgmt/p5-SNMP_Session/work/SNMP_Session-
1.12/lib/SNMP_util.pm

 /usr/ports/net-mgmt/p5-SNMP_Session/work/SNMP_Session-
1.12/blib/lib/SNMP_util.pm

locations and try running mrtg again. It should print out any MIB file 
it tries to load.



Do you have multiple 'LoadMibs:' directives in your configuration? It's 
possible mrtg is only using the last one. If you have multiple MIB 
files to load you can list them all on one line, separated by a comma.

Hi Mike,

Thank you so much for the reply, I replaced my SNMP_util.pm file with 

the one you send it across and I found no changes at all in mrtg log. 

So its almost clear now that the LoadMIBs doesn't touch the squid.mib 

file at all.

Below are the log details

Where I have SNMP_util.pm files



testmc# find / -name SNMP_util.pm

/usr/local/lib/perl5/site_perl/5.10.1/SNMP_util.pm

/usr/ports/net-mgmt/p5-SNMP_Session/work/SNMP_Session-

1.12/lib/SNMP_util.pm

/usr/ports/net-mgmt/p5-SNMP_Session/work/SNMP_Session-

1.12/blib/lib/SNMP_util.pm

/usr/home/babs/SNMP_util.pm





Also the top portion of mrtg.cfg 



testmc# head -4 /usr/local/etc/mrtg/mrtg.cfg

EnableIPv6: no

WorkDir: /usr/local/www/apache22/data

Options[_]: bits,growright

LoadMIBs: /usr/local/etc/mrtg/squid.mib





May be these things may help you, I suppose?



Still scratching my head to get a clue



With thanx & regards

Babs
