Nagios Support Forum

I have a few linux machines that I have nagios monitoring.

I dont remember the process for setting up a client on the linux machines, and now I have more I need to add.

The only documentation I saw for linux machinces is using nrpe. I dont remember it being so many steps.

Is there another way to monitor a linux host other than NRPE?

Yes. One of the easiest ways it to put the modules on the remote Linux box and then use check_by_ssh to check them from the Nagios host. This requires SSH keys with no passphrase, but can be set up in a few seconds, rather than the hour or so it might take to set up NRPE.

Another method of monitoring without an NRPE agent would be snmp. That process is documented here:

I would argue that monitoring via SNMP is more complex than monitoring via NRPE.

When you say

One of the easiest ways it to put the modules on the remote Linux box and then use check_by_ssh to check them from the Nagios host.

What modules do you mean?

You have to compile the Nagios plugins on the remote linux host (or compile them on a Linux host that has the same OS version and copy them). Things like check_cpu, check_disk, check_whatever. Those are the modules (or plugins). You can then call them via check_by_ssh on the Nagios host.

Part of the install instructions I wrote for myself includes:

wget https://www.nagios-plugins.org/download ... 2.0.tar.gz

are those the plugins you mentioned?

Yes!

Let us know how you get along with this, we're more than happy to answer any questions you have.

All seems to be working well.
