25 .Nd configuration file for sensorsd
31 to configure hardware sensor monitoring.
32 Each sensor registered in the system
33 is matched by at most one entry in
35 which may specify high and low limits,
36 and whether sensor status changes provided by the driver should be ignored.
37 If the limits are crossed or if the status provided by the driver changes,
39 alert functionality is triggered and a command, if specified, is
43 follows the syntax of configuration databases as documented in
45 Sensors may be specified by their full
48 variable name or by type,
49 with the full name taking precedence.
50 For example, if an entry
51 .Dq hw.sensors.lm0.temp1
52 is not found, then an entry for
54 will instead be looked for.
56 The following attributes may be used:
58 .Bl -tag -width "commandXX" -offset indent -compact
60 Specify a command to be executed on state change.
62 Specify an upper limit.
64 Specify a lower limit.
66 Ignore status provided by the driver.
69 The values for temperature sensors can be given in degrees Celsius or
70 Fahrenheit, for voltage sensors in volts, and fan speed sensors take a
71 unit-less number representing RPM.
72 Values for all other types of sensors can be specified
73 in the same units as they appear under the
78 Sensors that provide status (such as those from
83 do not require boundary values specified
84 and simply trigger on status transitions.
85 If boundaries are specified nonetheless,
86 then they are used in addition to automatic status monitoring,
89 attribute is specified to ignore status values that are provided by the drivers.
91 The command is executed when there is any change in sensor state.
92 Tokens in the command are substituted as follows:
94 .Bl -tag -width Ds -offset indent -compact
96 the xname of the device the sensor sits on
102 the sensor's current value
104 the sensor's low limit
106 the sensor's high limit
111 monitors status changes on all sensors that keep their state.
112 This behaviour may be altered by using the
115 status changes of sensors of a certain type
116 or individual sensors.

125 if hw.sensors.ipmi0.temp0 transitions 80C or
126 if its status as provided by
129 .Pa /etc/sensorsd/log_warning
131 with the sensor type, number and current value passed to it.
133 if hw.sensors.lm0.volt3 transitions to being within or outside
134 a range of 4.8V and 5.2V;
135 if the speed of the fan attached to hw.sensors.lm0.fan1
136 transitions to being below or above 1000RPM;
137 if any RAID volume drive
138 changes its status from, for example,
140 such as in the case of drive failure, rebuild, or a complete failure,
142 .Pa /etc/sensorsd/drive
143 will be executed, with the sensor number passed to it; however,
144 no alerts will be generated for status changes on timedelta sensors.
145 For all other sensors whose drivers automatically provide
146 sensor status updates, alerts will be generated
147 each time those sensors undergo status transitions.

168 The format was altered in
170 to accommodate hierarchical device-based sensor addressing.
173 attribute was introduced in
176 Alert functionality is triggered every time there is a change in sensor state;
180 the status of each monitored sensor changes
181 from undefined to whatever it is.
182 One must keep this in mind when using commands
183 that may unconditionally perform adverse actions (e.g.\&
185 as they will be executed even when all sensors perform to specification.
186 If this is undesirable, then a wrapper shell script should be used instead.
