Nagios Support Forum

Ok I have done that:

1st) I have gone to nrpe.cfg file and I add the remote host ip on the part of allowed_hosts.

2nd) I have defined the check_mailq command on the nrpe.cfg file.

3rd) I have definded the command nrpe, on the commands.cfg.

4th) I have defined de service, on the services.cfg file.

5th) I have done a service nagios restart.

And finaly on my web monitoring interface says to me, that the command is not definded.

To clarify, what server did you add the command[check_mailq]= part (the part you highlighted)?

If it was on the client machine, did you restart the NRPE / xinetd service?

I put that on the nagios host, Have I put it on the remote host I want to monitor?

The thing is that if I log me on the remote server via putty, and y put the mailq command on the command line, it returns me the correct information, but I want to see that information on the nagios web interface

Yes, put it on the remote host you'd like to monitor. Then restart the NRPE / xinetd service.

What will then happen is Nagios will call the check_mailq command on your client machine, then the client machine will execute the check_mailq plugin and send the data back to the Nagios server.

Have I to put it only on the nrpe.cfg host remote file or in someone else?

Because there are other files about nrpe

What is in the folder above? This looks like the sample config folder.

On the second file for example, there is a part that seems like that

Those are the sample files, not the actual configuration. That is why I asked what is in the directory above.

The directory above is this, and I was on the yellow directory

It doesn't look like NRPE is compiled - did you compile it yet?

Here's a document that explains how to configure / compile NRPE -
