hardware sensors monitor
utility retrieves sensor monitoring
data like fan speed, temperature, voltage and RAID logical disk status via
. When the state of any
monitored sensor changes, an alert is sent using
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
, indicating whether the sensor is within
or is exceeding its limits.
Limit and command values for a particular sensor may be specified in the
configuration file. This file is reloaded upon receiving
The options are as follows:
- Check sensors every check
seconds. The shortest reporting period for state changes will be three
times this value. The default is 20.
- Do not daemonize. If this option is specified,
sensorsd will run in the foreground.
- Read configuration from
file instead of the default configuration

Certain sensors may flip status from time to time. To guard against false
implements a state dumping
mechanism. However, this inevitably introduces an additional delay in status
reporting and command execution, e.g. one may notice that
makes its initial report about the state
of monitored sensors not immediately, but about 60 seconds after it is
