check_bioctl - checks status of a RAID array using bioctl

This check is for OpenBSD machines with bioctl(8) supported RAID cards.

The only real caveat with it is that bioctl needs rw permission to
/dev/bio. One way to allow for that is by adding an entry to
/etc/doas.conf.

This is an example of a setup for NRPE. For checks on the machine running
Nagios, use the _nagios user in /etc/doas.conf instead of _nrpe, and of course,
no /etc/nrpe.cfg. check_bioctl runs bioctl once for each device, so
you will need a doas.conf entry that matches each device you wish to check. If
you have multiple RAID volumes, you'll need one permit rules per volume.

/etc/doas.conf:
permit nopass _nrpe as root cmd /sbin/bioctl args ami0
permit nopass _nrpe as root cmd /sbin/bioctl args ami1

/etc/nrpe.cfg:
command[check_bioctl]=/usr/local/libexec/nagios/check_bioctl -d ami0 -d ami1

For more information on bioctl(8) see the OpenBSD man page.
