<mailto:[email protected]>Hello,
I encountered the problem when snmp agent reported to be down on some
servers with the message:
2008-10-27 12:50:40 ERROR zen.zenperfsnmp: Failed to collect on web01
(twisted.python.failure.Failure: [Failure instance: Traceback (failure
with no frames): twisted.internet.error.TimeoutError: User timeout
caused connection failure.
Nothing helps:
- restarting of zenperfsnmp from web GUI or command line
- restarting of whole bunch of zenoss daemons
- changing MAX_OIDS_PER_REQUEST in zenperfsnmp.py or per device
zMaxOIDPerRequest to 20 and even less
- raising zSnmpTimeout to 15 or even 20 seconds
- changing monitors snmp timeouts in dmd/manage interface
- deleting and recreating servers' devices in Zenoss
- removing cache files in zenoss/var
And the most weird thing is that everything works from command line of
zenoss host e.g.
snmpwalk
or
zenperfsnmp run -v -d <device>
and modeling works just fine for failing devices.
We rely on snmp to watch running processes, network interfaces and many
other stuff.
Please help!
Thanks in advance,
Andriy
