The sensorsd
utility retrieves sensor
monitoring data like fan speed, temperature, voltage and RAID logical disk
status via sysctl(3). When
the state of any monitored sensor changes, an alert is sent using
syslog(3) and a command, if
specified, is executed.
By default, sensorsd
monitors status
changes on all sensors that keep their state, thus sensors that
automatically provide status do not require any additional configuration. In
addition, for every sensor, no matter whether it automatically provides its
state or not, custom low and high limits may be set, so that a local notion
of sensor status can be computed by sensorsd
,
indicating whether the sensor is within or is exceeding its limits.
Limit and command values for a particular sensor may be specified
in the
sensorsd.conf(5)
configuration file. This file is reloaded upon receiving
SIGHUP
.
The options are as follows:
sensorsd
.The sensorsd
program first appeared in
OpenBSD 3.5.
Certain sensors may flip status from time to time. To guard
against false reports, sensorsd
implements a state
dumping mechanism. However, this inevitably introduces an additional delay
in status reporting and command execution, e.g. one may notice that
sensorsd
makes its initial report about the state of
monitored sensors not immediately, but about 60 seconds after it is
started.
