I have an EMC NX4 that Im trying to monitor via Nagios. The command being sent is

check_snmp -H<server> -P1 -Cpublic -oDISMAN-EVENT-MIB::sysUpTimeInstance -r Timeticks

What I get back is

SNMP problem - No data received from host
CMD: /usr/bin/snmpget -t 1 -r 5 -m ALL -v 1 [authpriv] <server>:161  DISMAN-EVENT-MIB::sysUpTimeInstance

This works on my other EMC device so there is something that needs to be installed on the NX4. What is it?

It looks like your server isn't getting an SNMP response from the NX4. There's not a lot of detail here, but here's how I would diagnose this:

  • Make sure you have network connection (ping)
  • One the NX4, make sure SNMP is turned on, and verify community strings
  • Use a tool like snmpwalk to make sure you can get a response to an SNMP query
  • Finally, check the MIB to make sure you've got the correct variable

Some devices will make a log entry for invalid SNMP requests (bad OID or community) - that may be useful as well for diagnosis.
