Use NSClient to monitor a machine its not installed on

[nathanplatt]

Hi Everyone,

Previous i logged a problem monitoring our QNAP where the plugin was timing out. This now happens daily and I was wondering how I could get another Server in its Physical location to pull the data for the plugin. rkennedy implied this is possible.

Any help would be appreciated

These guides explain how to allow NSClient++ to perform checks against other NSClient++ instances:

Is this what you are looking for?

I think I understand that, but the device I'm trying to monitor is SNMP only. I can't install NSClient on it as its a custom web based config. Is there a way for another machine to pull the snmp information to it and then relay to Nagios stored at a different site. (Both sites are connected over VPN)

A windows machine will be difficult to do that with.

If you had a linux machine at the site, you could install NRPE on it and the nagios plugins with SNMP support. Then based on my guide you could use the NRPE client to do the SNMP checks.

Alternatively you could have a linux machine at the site and install a Mod-Gearman worker on it to execute the checks.
Here are some Mod-Gearman guides:

Would a Raspberry Pi would be powerful enough to accomplish this?

[Box293]

It should be possible, the newer versions of Pi seem to be more powerful.

I'm not sure what type of compatibility you may face running Raspbian and Mod-Gearman. I would be included to run the same OS that your Nagios server is to keep things simple.

Ah, well Nagios is on Centos 7, so not sure how well it'll run. I'll do some tests on this site and see how it works. Consider the tread closed and I'll try the solutions you've linked!

Thanks again
