Nagios Support Forum

Hi

I would like to monitor the ping response from one machine to another machine via nagios.

Kindly let me know the possibilities.

Thanks in advance.

The base Nagios plugins suite includes the check_ping plugin for this use case:
http://nagios-plugins.org/doc/man/check_ping.html

Here's a few examples of the plugin's usage:

As far as how you turn that command execution into something Nagios can understand and regularly monitor, the "quickstart" documentation is a good place to start:
https://assets.nagios.com/downloads/nag ... start.html

And if it's a bit difficult to digest, feel free to ask questions or request examples on the forums.

Thanks for the assist, @mcapra! OP, please let us know if you need further assistance.

Hi @mcapra

Thanks for your response.

I have already configured ping check to ping different hosts from my Nagios server.

but, my scenario is different, here it is.

I have 2 hosts A & B already added to Nagios server and check_ping is enabled from Nagios to Host A & B.

Now, i would like to check ping from host A to B i.e Nagios initiate check to host A and host A has to initiate check_ping to host B.

Let me know if this is possible, then how?

I see two options here (both in shortened form, some extra options might be required):
a) check_by_ssh -H hostA -C '<nagios_plugin_path>/check_ping hostB'
b) check_nrpe -H hostA -c check_ping_hostB

Yes, install NRPE on host A

Then add a new command to the nrpe.cfg that pings host B

Call this with check_nrpe from nagios server
