Just installed Nagios 3.2 and have it monitoring 4 or 5 windows hosts as well as itself. The localhost (Ubuntu 10.04) has SSHD configured, but I've changed the port it's listening on. Nagios hates this.
How do I change the port that Nagios checks to see that my SSH server is functional?
I've spent quite some time RTFM and ♫♪ I still haven't found what I'm looking for ♫♪.
Have you looked at the output of check_ssh -h ? You can use the -p option to specify the port. Or use check_tcp with the same option for a more generic check.
