<h1>Nagios Check - check_hw_sensors</h1>

check_hw_sensors plugin for Nagios monitors sysctl hw.sensors on OpenBSD

With the new sensor framework in OpenBSD 3.9, I wanted to be able to monitor the new hw.sensors from <a href='http://www.nagios.org/'>Nagios</a> and this is what I have. The documentation is a bit thin and I don't know how reliable it is. I would be happy to accept patches. Send them to <a href='mailto:andrew+nagios@rraz.net'>andrew+nagios@rraz.net</a>. I know the docs aren't as good as I would like, so if there are places that need clarification, please let me know!

New in this release is support for more sensor types, as well as support for OpenBSD 4.0.

New in this release is support for the new 2 level sensors in OpenBSD 4.0-current. They seem way more better, and I may change some stuff to only support that version after I get all my machines moved to 4.1

It has the ability to check the sensors that report their status. Since many sensors support this, it can make the size of your sensorsd.conf much smaller. For example, check_hw_sensors will automatically check these two sensors:

<ul>

<li>hw.sensors.76=esm0, Fan 4, 3629 RPM, OK</li>

Line 17

<li>the RANGE using the colon to separate probably screws up the getcap of sensorsd.conf, so it should probably get replaced with a dash or somesuch</li>

</ul>

If you are using --ignore-status, you can still check the status of

individual sensors with a status entry.
