this service shows the following error:

COMMAND: /usr/local/nagios/libexec/check_snmp -H 10.202.6.23 -P 2c -C public -o numberOfSessions.6 -u sessions --rate --rate-multiplier 300 -w 5: -c 1: -t 30

[07-02-2014 10:54:01] SERVICE ALERT: jaw-mas-001;Paltel Sessions;UNKNOWN;SOFT;3;External command error: Error in packet

Does it work if you use the full OID instead of "-o numberOfSessions.6"?

What does a snmpwalk reveal about numberOfSessions.6?

[root@nms ~]# /usr/local/nagios/libexec/check_snmp -H 10.202.6.23 -P 2c -C public -o numberOfSessions.6 -u sessions --rate --rate-multiplier 300 -w 5: -c 1: -t 30
External command error: Error in packet
Reason: (genError) A general failure occured
Failed object: GLENAYRE-ILSP2-ASU-ALARMS-MIB::numberOfSessions.6

please what is the command for snmpwalk and full OID?

You can run:
then open the "snmpwalk.txt" file that was created from running the above command in a text editor and review it.

You can walk a specified OID by passing the "-CE" flag to your command.

I run the command . please find attached snmpwalk, but is the result which can I get to fix this case.

Rerun the command as such:
and post the "snmpwalk2.txt" file.

Also, upload the "GLENAYRE-ILSP2-ASU-ALARMS-MIB".

please find the attached.

It doesn't look like your snmpwalk came up with any oids that would match your mib. We can try a few other commands and see what comes up, but I would also ask if this is supposed to integrate with the default linux snmp agent or if this provides it's own agent.

when I run the command. the following, and all the files empty:

If you are getting a timeout with snmpwalk, then there are a few things to check:

1. Is the community name correct?
2. Does the host allow your nagios server to connect to it with that community name?
3. UDP port 161 must be open from your Nagios server to your server name
