On your remote server, can you run the following and post the output?
ls -l /usr/lib64/nagios/plugins

The plugins may already be installed on your remote server, as the above command will verify that.

To check your remote server, you will have to use the check_nrpe command in your Nagios server with the command that is defined in the nrpe.cfg file.
For example, to run the check_load on the remote server, you would run this on the nagios server.

/usr/local/nagios/libexec/check_nrpe -H xxx.xxx.xxx.xxx -c check_load

xxx.xxx.xxx.xxx would be the IP address of the remote server.
This will run the command on the remote server and return the results to the nagios server.

But, it looks like you do not have the check_nrpe command on your Nagios server, take a look at this doc for more information on how to do that.
http://nagios.sourceforge.net/docs/nrpe/NRPE.pdf

I've installed nrpe according to https://assets.nagios.com/downloads/nag ... e/NRPE.pdf
But I don't have the file in accord to this test:

I have this:

[tgriep]

Try installing NRPE from source and see if that works.

This guide shows you how to just install the check_nrpe plugin:

On the monitoring server (Ubuntu 14.04) I've installed nrpe with ./configure --disable-ssl, because make all didn't work for me:

On the remote server (CentOS 6.5) I installed nrpe without problems and the file check_nrpe appeared. But when I try to launch check_nrpe from this server to the monitoring one it says:

And when I try to launch check_nrpe from monitoring server to the remote one it says:

[tgriep]

If you didn't install NRPE with SSL enabled, then you have to add the -n option to the check_nrpe command which disables the use of SSL.
Here is the check_nrpe usage

Options:
-n = Do no use SSL
-u = Make socket timeouts return an UNKNOWN state instead of CRITICAL
<host> = The address of the host running the NRPE daemon
<bindaddr> = bind to local address
-4 = user ipv4 only
-6 = user ipv6 only
[port] = The port on which the daemon is running (default=5666)
[timeout] = Number of seconds before connection times out (default=10)
[command] = The name of the command that the remote daemon should run
[arglist] = Optional arguments that should be passed to the command. Multiple
arguments should be separated by a space. If provided, this must be
the last option supplied on the command line.

Note:
This plugin requires that you have the NRPE daemon running on the remote host.
You must also have configured the daemon to associate a specific plugin command
with the [command] option you are specifying here. Upon receipt of the
[command] argument, the NRPE daemon will run the appropriate plugin command and
send the plugin output and return code back to *this* plugin. This allows you
to execute plugins on remote hosts and 'fake' the results to make Nagios think
the plugin is being run locally.

Here is an example of how you would run the command.

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H 192.168.1.2 -n

Also, take a look at the NRPE Troubleshooting guide for help.

Please show us the full input / output.

When you run the command from the Nagios server, look at your /var/log/messages for a corresponding error message, and post that for us as well.

Take a look at the troubleshooting guide but it looks like the NRPE agent isn't running on the remote servers.
Can you verify that the NRPE Agent is configured to run on those servers.
