Issue is still happening

Basically this issue comes down to the Nagios server not getting a response in a timely manner from the server you are connecting to. Which unfortunately is somewhat common with udp over wider network segments.

The only 2 things remaining would be to yet again increase the timeout, or, alternately, install an agent on or closer to the device you are polling to hopefully to eliminate the possibility of the udp packet getting dropped.

HI Scott,

Thanks for this, when you say agent. Do you mean a whole nagios server?

No, I mean like our NRPE agent

[nathanplatt]

Ah well in this case it's pulling the information from the Storage device directly using SNMP. There's no agent on the device

What Scott is mentioning, is SNMP uses UDP. As you're doing SNMP checks, you have two options -

The only 2 things remaining would be to yet again increase the timeout, or, alternately, install an agent on or closer to the device you are polling to hopefully to eliminate the possibility of the udp packet getting dropped.

This suggests to either increase the timeout higher than 20. The second option is to use an agent on this machine (rather than SNMP), or an agent at the same location as this machine to poll the device (using NSClient++ or NRPE).

Okay thank you guys, i'll work on the timeout variable till i get the right amount, please close case.

Roger that. Closing and out.

Feel free to create a new thread if you need any assistance in the future.
