3: <h1>Nagios Check - check_hw_sensors</h1>
4: <p>check_hw_sensors plugin for Nagios monitors sysctl hw.sensors on OpenBSD</p>
5: <p>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. It is currently a work in progress although it does seem to work just fine. 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!</p>
6: <p>What I think is really kewl about this plugin is that it can use the same sensorsd.conf as sensorsd. That means that they can be easily kept in sync. But, since Nagios supports both warning and critical alerts, it turned out really handy that sensorsd ignores any additional capabilities in the file. The addtional capabilities check_hw_sensors supports are described below. If you have an /etc/sensorsd.conf with the checks you want, it can be run as simply as 'check_hw_sensors -f'.</p>

20: check_hw_sensors (-f [<FILENAME>]|(-s <hw.sensors id> -w limit -c limit))
21:
22: Usage:
23: -f, --filename=FILE
24: FILE to load checks from (defaults to /etc/sensorsd.conf)
25: -s, --sensor=ID
26: ID of a single sensor. "-s 0" means hw.sensors.0.
27: -w, --warning=RANGE or single ENTRY
28: Exit with WARNING status if outside of RANGE or if != ENTRY
29: -c, --critical=RANGE or single ENTRY
30: Exit with CRITICAL status if outside of RANGE or if != ENTRY
31:
32: -h (--help) usage help
33: </pre>
34: <p>FILE is in the same format as <a href='http://www.openbsd.org/cgi-bin/man.cgi?query=sensorsd.conf'>sensorsd.conf(5)</a> plus some additional entries. These additional entries in the file are ignored by <a href='http://www.openbsd.org/cgi-bin/man.cgi?query=sensorsd'>sensorsd(8)</a>. </p>
35:
36: <p>check_hw_sensors understands the following entries:<br>
37: low, high, crit, warn, crit.low, crit.high, warn.low, warn.high</p>
38:
39: <p>An ENTRY depends on the type. The descriptions in <a href='http://www.openbsd.org/cgi-bin/man.cgi?query=sensorsd.conf'>sensorsd.conf(5)</a>
40: can be used when appropriate, or you can use the following:
41:
42: <ul>
43: <li>volts_dc, fanrpm or raw<br>
44: Anything that includes digits.
45: Both the value of the check and the value of the sensor
46: response that are not either a digit or period are stripped
47: and then the two resultant values are compared.</li>
48:
49: <li>temp<br>
50: Can be as above, but if the entry has an F in it,
51: it compares farenheit, otherwise it uses celcius.</li>
52:
53: <li>indicator or drive<br>
54: does a case sensitive match of each
55: entry in the comma separated list and if it does not match
56: any of the entries, it matches the status. Does not support any low or high entries.</li>
57: </ul>
58:
59: <p>The entries 'crit' or 'warn' (or the -c or -w on the command line)
60: may be a RANGE or a comma separated list of acceptable values.
61: The comma separated list of values contains a list of things that
62: will NOT cause the status. This is possibly counterintuitive, but
63: you are more likely to know good values than bad values.</p>
64:
65: <p>A RANGE is a low ENTRY and a high ENTRY separated by a colon (:).
66: It can also be low: or :high with the other side left blank to only
67: make the single check..<p>
