|SENSORSD(8)||System Manager's Manual||SENSORSD(8)|
sensorsdutility 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.
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
indicating whether the sensor is within or is exceeding its limits.
Limit and command values for a particular sensor may be specified

The options are as follows:
sensorsdwill run in the foreground.
sensorsdprogram first appeared in OpenBSD 3.5.
sensorsdimplements a state dumping mechanism. However, this inevitably introduces an additional delay in status reporting and command execution, e.g. one may notice that
sensorsdmakes its initial report about the state of monitored sensors not immediately, but about 60 seconds after it is started.
