sensorsd —
hardware sensors monitor

[-d] [-c

file] |
The 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.The sensorsd program first appeared in
OpenBSD 3.5.
Certain sensors may erratically flip status from time to time. To
guard against false reports, 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.
