greetings
I am trying to use MRTG with the LoadMIBs option, while I've been
using MRTG for years I haven't tried this option before. Specifically
I am trying to load the MIBs for squid ..
sample config:
WorkDir:/home/mrtg/public_html/squid/
LoadMIBs: /usr/lib/squid/mib.txt
Target[squid.cache.client.usage]:
"squid.cachePerf.cacheProtoStats.cacheMedianSvcTable.cacheMedianSvcEntry.cacheMedianTime.5:public@localhost:3401"Title[squid.cache.client.usage]:
Client IP Accesses
PageTop[squid.cache.client.usage]: <H1>Cache Statistics: # of Client IPs
accessing cache</H1>
LegendI[squid.cache.client.usage]: Client Accesses
LegendO[squid.cache.client.usage]:
Legend1[squid.cache.client.usage]: Client Accesses
Legend2[squid.cache.client.usage]:
YLegend[squid.cache.client.usage]:
MaxBytes[squid.cache.client.usage]: 100
Options[squid.cache.client.usage]: gauge
but even running strace -fF mrtg <filename> results in not even a single
mib access.. that is:
strace -fF mrtg squid.conf2 >&/tmp/squid.out
grep -i mib /tmp/squid.out
nothing comes back..so that tells me it's not even trying to load
the file ??
I have a buncha other squid variables that seem to work fine(without the
MIB).
also I have tested this MIB with snmpwalk, it does NOT work unless I
load the MIB:
snmpwalk -m /usr/lib/squid/mib.txt -Ci -p 3401 -IR localhost public
squid.cachePerf.cacheProtoStats.cacheMedianSvcTable.cacheMedianSvcEntry.cacheHttpAllSvcTime.5enterprises.nlanr.squid.cachePerf.cacheProtoStats.cacheMedianSvcTable.cacheMedianSvcEntry.cacheHttpAllSvcTime.5=
15
snmpwalk -Ci -p 3401 -IR localhost public
squid.cachePerf.cacheProtoStats.cacheMedianSvcTable.cacheMedianSvcEntry.cacheHttpAllSvcTime.5squid.cachePerf.cacheProtoStats.cacheMedianSvcTable.cacheMedianSvcEntry.cacheHttpAllSvcTime.5:Unknown
Object Identifier
so I know the MIB is working ..anyone have any ideas what could be
going wrong ?
I am running woody with mrtg 2.9.17-4
when I run mrtg with this config now I get:
SNMP Error:

I hope to use this option with a set of MIBs for my extreme summit 48
switch too if I can get MRTG to read the MIBs ..
thanks
