check_bioctl plugin for Nagios monitors RAID arrays on OpenBSD using bioctl.
-The new raid framework in OpenBSD is really kewl. The fact the commands are the same, no matter which RAID card you use is just amazingly handy.
+The check_bioctl plugin for Nagios monitors RAID arrays on OpenBSD using bioctl.
+The only real caveat with it is that bioctl needs rw permission to /dev/bio. The way I allow for that is by adding an entry to /etc/sudoers and then making the check run sudo check_bioctl.
I wrote this on OpenBSD 3.9 and tested on Dell PERC 3/DC controllers using the ami driver. It should work just fine on other versions of OpenBSD as well as with other cards and drivers. If you do run into trouble, send me the output from bioctl on the system you are having trouble with and I can try to help. Patches to fix problems would be even better.
+check_bioctl also uses utils.pm from the Nagios Plugins package, so that needs to be installed.

++ This is an example of what I have set up for NRPE. For checks on the machine running Nagios, use the _nagios user in /etc/sudoers instead of _nrpe, and of course, no /etc/nrpe.cfg. +check_bioctl plugin for Nagios monitors bioctl on OpenBSD check_bioctl -d <device> [ -d <device2> [ -d ... ] ] @@ -33,13 +35,19 @@ -h, --help usage help -V, --version version information -check_bioctl (nagios-plugins 1.4.2) 1.3 +check_bioctl (nagios-plugins 1.4.2) 1.4 The nagios plugins come with ABSOLUTELY NO WARRANTY.
