Hi

What is a good way to check if nrpe service is running? I set the NRPE checks to report as UNKNOWN if there is issues because I want to avoid firing lots of alerts just because the server is going down and stops the nrpe service.

I tried to monitor the TCP port 5666. But that creates SSL Handshake messages. Then I tried to use NMAP which causes other issues

Code: Select all

015-11-16T11:31:37.940060+01:00 Error: Network server getpeername() failure (107: Transport endpoint is not connected)
2015-11-16T11:31:37.940223+01:00 Cannot remove pidfile '/var/run/nrpe/nrpe.pid' - check your privileges.
2015-11-16T11:31:37.940281+01:00 Daemon shutdown

Any ideas? I use the following NMAP command

Code: Select all

nmap -Pn host -p 5666

Just do a "check_nrpe -H hostaddress"

That should return with the version of NRPE running, if not, then issue.

Thanks @BanditBBS! Does that answer your question @sib?

So simple. And I have not thought about it

Great thanks

Great, any more questions on it or are we okay to mark it as resolved and lock the topic?
