By explicitly setting "cpu.percpu=True" as parameter, it is now possible to get the CPU utilization on a per-cpu basis. Future extension: One widget per CPU (add ID of CPU and add warning/error state on a per CPU basis) see #785

"""Displays CPU utilization across all CPUs.
|
|
|
|
By default, opens `gnome-system-monitor` on left mouse click.
|
|
|
|
Requirements:
|
|
* the psutil Python module for the first three items from the list above
|
|
* gnome-system-monitor for default mouse click action
|
|
|
|
Parameters:
|
|
* cpu.warning : Warning threshold in % of CPU usage (defaults to 70%)
|
|
* cpu.critical: Critical threshold in % of CPU usage (defaults to 80%)
|
|
* cpu.format : Format string (defaults to '{:.01f}%')
|
|
* cpu.percpu : If set to true, show each individual cpu (defaults to false)
