UESENSOR(8) Linux on Power Service Tools UESENSOR(8)NAMEuesensor - view the state of system environmental sensors
SYNOPSIS
/usr/sbin/uesensor -l | -a
/usr/sbin/uesensor -t token -i index [-v]
DESCRIPTION
The uesensor utility is used to view the state of environmental sensors
on PowerPC-64 machines.
There are 4 types of system sensors that can be retrieved with uesenâ
sor; each sensor has an identifying token:
3 Thermal sensor
9001 Fan speed sensor
9002 Voltage sensor
9004 Power supply sensor
Each sensor is uniquely identified by a combination of token and index
number; index numbers start at 0 and are contiguous. For example, the
second fan on the system would be identified by token number 9001 and
index 1.
The state of each sensor consists of a status and a measured value.
The status value is one of the following:
9 Critical low
10 Warning low
11 Normal
12 Warning high
13 Critical high
The measured value depends on the type of sensor. Thermal sensors are
measured in degrees Celcius; fan speed is measured in revolutions per
minute; voltage is measured in millivolts; power supply measurements
are defined as follows:
0 Not present
1 Present and not operational
2 Status unknown
3 Present and operational
Each sensor is also associated with a location code; this location code
may not be unique (for example, there may be multiple voltage sensors
on a planar).
OPTIONS-l List all the sensors in human-readable format.
-a List all the sensors in a tabular, numerical format. One line
will be printed for each sensor in the following format:
<token> <index> <status> <measured_value> <location_code>
-t token
Specify the token of a specific sensor to query. Also requires
the -i option to be specified.
-i index
Specify the index of a specific sensor to query. Also requires
the -t option to be specified.
-v Print the measured value rather than the sensor status, which is
the default value printed. Requires both the -t and -i options
to be specified.
