     sensorsd - hardware sensors monitor

     sensorsd [-d] [-c check]

     The sensorsd utility retrieves sensor monitoring data like fan speed,
     temperature, voltage and ami(4) 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:

     -c check
	     Check sensors every check seconds.	 The shortest reporting period
	     for state changes will be three times this value.	The default is

     -d	     Do not daemonize.	If this option is specified, sensorsd will run
	     in the foreground.

     /etc/sensorsd.conf	 Configuration file for sensorsd.

     sysctl(3), syslog(3), sensorsd.conf(5), syslogd(8)

     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.
