A few NRPE probes are available in the probes/ subdirectory.
Some of these probes might need to have elevated rights, an example of sudoers file is included.
You might want to also use the nice check_logfiles probe, courtesy of
Consol Labs (https://labs.consol.de/nagios/check_logfiles/index.html), to ensure
that the cron scripts behave correctly and that no error is happening during the backup process,
the encrypt & rsync process, the HA synchronization daemon, etc.
The configuration of the check_logfiles probe can be found in etc/nagios/plugins.d.
The bastion-side NRPE daemon configuration for these probes can be found in the etc/nagios/nrpe.d.
