1.2       andrew      7:                <p>The check_bioctl plugin for <a href="http://www.nagios.org">Nagios</a> monitors RAID arrays on <a href="http://www.openbsd.org">OpenBSD</a> using <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=bioctl">bioctl</a>.</p>
                      8:                <p>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 <code>sudo check_bioctl</code>.  </p>
                      9:                <p>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.</p>
                     10:                <p>check_bioctl also uses utils.pm from the <a href="http://www.openbsd.org/3.9_packages/i386/nagios-plugins-1.4.2.tgz-long.html">Nagios Plugins</a> package, so that needs to be installed.</p>
