I have been following this thread with some interest.
What is meant by "No MRTG response"?
Most of the time, MRTG takes advantage of the SNMP_Util module to query the
intended target, right?
So, why not write a small SNMP query before MRTG scan and if fail, send an
email or somrthing?
For example, before I start my MRTG run, I PING the target. If it fails,
then I send an email and move onto the next target. Etc., etc. Works
If I were doing it via SNMP, then I would use the SNMP_Util module, and
query the sysDescr or sysObjectID value, and make sure I get a valid return
(i.e. not 0 or undef).
Beyond that seems to me that you would be doubling up on the query if you
were to test each target OID before MRTG was.
... Or am I way out in left field?
