"""Multiwidget CPU module
|
|
|
|
Can display any combination of:
|
|
|
|
* max CPU frequency
|
|
* total CPU load in percents (integer value)
|
|
* per-core CPU load as graph - either mono or colored
|
|
* CPU temperature (in Celsius degrees)
|
|
* CPU fan speed
|
|
|
|
Requirements:
|
|
|
|
* the psutil Python module for the first three items from the list above
|
|
* sensors executable for the rest
|
|
|
|
Parameters:
|
|
* cpu2.layout: Space-separated list of widgets to add.
|
|
Possible widgets are:
|
|
* cpu2.maxfreq
|
|
* cpu2.cpuload
|
|
* cpu2.coresload
|
|
* cpu2.temp
|
|
* cpu2.fanspeed
|
|
* cpu2.colored: 1 for colored per core load graph, 0 for mono (default)
|
|
if this is set to 1, use --markup=pango
|
|
* cpu2.temp_pattern: pattern to look for in the output of 'sensors -u';
|
|
required if cpu2.temp widged is used
|
|
* cpu2.fan_pattern: pattern to look for in the output of 'sensors -u';
|
|
required if cpu2.fanspeed widged is used
|
|
|
|
Note: if you are getting 'n/a' for CPU temperature / fan speed, then you're
|
|
lacking the aforementioned pattern settings or they have wrong values.
