NRPE - Nagios Remote Plugin Executor, used to remotely execute Nagios plugins.

NRPE allows you to remotely execute Nagios plugins on other Linux/Unix machines. This allows you to monitor remote machine metrics (disk usage, CPU load, etc.). NRPE can also communicate with some of the Windows agent addons, so you can execute scripts and check metrics on remote Windows machines as well.

NRPE and Perl - cannot include ANYTHING or it breaks

I've been banging my head off NRPE and Perl for weeks now. I decided to start from absolute first principles, and create a dummy nagios plugin that does nothing but always returns OK. I called it check_true.pl, installed it on the remote server and…
