This fixed some of the machines, we are going through each one of our VM's with time out issue to figure out the cause. Some seem to have issue with SNMP not working properly. We are working with our System admins to sort the SNMP issues. Will update you soon on the status.

OK, thanks for reporting back. If you have any questions, let us know.

How do we go about fixing the following error on Linux machine?


LUTL-NAGIOSXI.ams.com>>/root>>time /usr/local/nagios/libexec/check_snmp_storage_wizard.pl -H 162.70.xx.xxx -C ARM1 --v2c -m 'Physical Memory' -w 80 -c 90 -f -t 60 --octetlength=65535
Unknown storage : Physical Memory : ERROR

real 0m0.209s
user 0m0.160s
sys 0m0.015s

The M in memory is lower case on Linux systems, try using the following command.
/usr/local/nagios/libexec/check_snmp_storage_wizard.pl -H 162.70.xx.xxx -C ARM1 --v2c -m 'Physical memory' -w 80 -c 90 -f -t 60 --octetlength=65535

That did the trick. Thank you.

There is one machine where we are getting unknown for CPU. Here are the details:

[[email protected] ~]$ /usr/local/nagios/libexec/check_snmp_load_wizard.pl -H 162.xx.xxx.xx -t 60 -C ARM1 --v2c -w 90 -c 95 -f
Can't find CPU usage information : UNKNOWN

It could be that the SNMP Daemon that is running on that system is not configured to respond the the CUP Load OID.
If you have another system that works, compare the settings in the snmpd.conf file and see if they match, and update them if needed.

[SETR]

Some of our Linux servers are having issues with the CPU load, we are using the same settings everywhere, not sure why only few are having these issues. Anything we can check to troubleshoot this issue?

[avandemore]

Is the SNMP daemon uniform in version and configuration?

[tmcdonald]

Just checking in since we have not heard from you in a while. Did @avandemore's post clear things up or has the issue otherwise been resolved?

[SETR]

Yes, now everything looks fine. On a different note, Is there a way to restart a VM from the NagiosXI web interface?
