I'm probably doing this the wrong way round, in which case I will happily stand
corrected. First here's what I'm trying to do, then how I'm doing it.
I want to monitor the resources, but of only a subset of processes. So, I set up
the monitor to watch a private OID, and then configured this OID to pass to my
python script.
The aim of the script is to translate this tree:
hrSWRunName
hrSWRunName.1
hrSWRunName.2
hrSWRunPerfCPU
hrSWRunPerfCPU.1
hrSWRunPerfCPU.2
to
privateOID
hrSWRunName.2
hrSWRunPerfCPU.2
where the .2 process is the one I'm interested in.
So my python script handles the get() and getnext() by talking back to the agent
and filtering out unwanted OIDs, then returning the result back to the calling
agent (snmpd)
This seemed to work fine - and in fact does work fine when I run from the
command-line. However when I make the call via snmpd (using snmpwalk, for
example) the call back into the agent fails thus:
File "/usr/local/lib/python2.4/site-packages/yapsnmp.py", line 257, in getnext
return self.__synch_response__(pdu, printoid=1)
File "/usr/local/lib/python2.4/site-packages/yapsnmp.py", line 216, in __synch
_response__
raise GetError, errmsg
[0]=yapsnmp.GetError
[1]=couldn't obtain response
Any ideas? Could this be achieved more elegantly without going out to an
external script?
Thanks
