I recently upgraded to mrtg + rrd + 14all (major kudos to Tobi and Rainer
and Paul for the help docs!).
I'm getting one really weird error that I can't troubleshoot past a certain
It's the old familiar:
no response received
SNMPv1_Session (remote host: "router" [ip.address.of.router].161)
request ID: 548025431
PDU bufsize: 8000 bytes
at /usr/local/mrtg/bin/../lib/mrtg2/SNMP_util.pm line 450
SNMPGET Problem for ifDescr.1 ifInOctets.1 ifDescr.1 ifOutOctets.1 on
public at router:
at ../../bin/mrtg line 1485
Here's the weirdness:
- cfgmaker picks up this interface with no errors.
- I can run a cli snmpget against all the oids in the error message, no
- The first time I run mrtg against this cfg, I don't get any errors.
- If I delete the .ok file, then run mrtg against this cfg, I don't get any
Weirdest of all:
the graph and rrd are still being updated.
I've checked the parts of the code referenced in the error, and still being
sort of a perl newbie, I'm completely confused as to what could be causing
this. (Of course I am also suffering from a major brainlock caused by
sendmail...) Anybody have any ideas about where to start troubleshooting
this/how to fix?
