sensorsd utility retrieves sensor monitoring data
like fan speed, temperature, voltage and RAID logical disk status from the
sysctl(2) hw.sensors
subtree. When the state of any monitored sensor changes, an alert is
triggered. Every alert logs a message to
syslog(3) using the
daemon facility. Optionally, an alert can be
configured to execute a command.
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:
-c
check-dsensorsd will run in the foreground.-f
filesensorsd.sensorsd program first appeared in
OpenBSD 3.5.
sensorsd requires two confirmations
before reporting a state change. 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 by default about 60
seconds after it is started.
