UESENSOR(8)

NAME
uesensor - 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 uesensor; 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.
