[mrtg] MRTG 2.9.17 w/LoadMIBs option

[nate]

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 at 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:UnknownObject Identifier

so I know the MIB is working ..anyone have any ideas what could be
going wrong ?

I am running Debian 3.0(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

nate
