Add Per-core Metrics on indicator-multiload on Ubuntu

Tested on Ubuntu 20.04

Install the plugin

$ sudo apt install indicator-multiload

Add per-core metrics to indicator

To add use percentages for each core, use this example: percent(cpu.cpu0.inuse)

• 1) Open Preferences -> Indicator Items

• 2) Add the following to the first slot (example for 8 cores):

  $(percent(cpu.cpu0.inuse)) | $(percent(cpu.cpu1.inuse)) | $(percent(cpu.cpu2.inuse)) | $(percent(cpu.cpu3.inuse)) | $(percent(cpu.cpu4.inuse)) | $(percent(cpu.cpu5.inuse)) | $(percent(cpu.cpu6.inuse)) | $(percent(cpu.cpu7.inuse))
  

Configuring indicator items with percent

RESULT: Added per-core percentage use to the indicator bar
(example for 8 cores)

Add per-core metrics to indicator, fixed width

It's annoying that the numbers keep moving depending on how much use you have.

To have fixed-width columns, use decimals(..., 2) instead of percentage:

• 1) Open Preferences -> Indicator Items...

• 2) Add the following to the first slot (example for 8 cores):

  $(decimals(cpu.cpu0.inuse,2)) | $(decimals(cpu.cpu1.inuse,2)) | $(decimals(cpu.cpu2.inuse,2)) | $(decimals(cpu.cpu3.inuse,2)) | $(decimals(cpu.cpu4.inuse,2)) | $(decimals(cpu.cpu5.inuse,2)) | $(decimals(cpu.cpu6.inuse,2)) | $(decimals(cpu.cpu7.inuse,2))
  

use decimals instead of percent to force fixed-width metrics

RESULT: Slightly different from the above:
per-core metrics are now formatted to use
2 decimals, which makes them have a fixed-width

(example for 8 cores)

Add per-core metrics to menu

You can also add the per-core metrics to the context menu instead of the indicator launch bar:

To have fixed-width columns, use decimals(..., 2) instead of percentage:

• 1) Open Preferences -> Menu Items...

• 2) Add the following to the first 8 slots (example for 8 cores):

  CPU0: $(percent(cpu.cpu0.inuse)
  CPU1: $(percent(cpu.cpu1.inuse)
  CPU2: $(percent(cpu.cpu2.inuse)
  CPU3: $(percent(cpu.cpu3.inuse)
  CPU4: $(percent(cpu.cpu4.inuse)
  CPU5: $(percent(cpu.cpu5.inuse)
  CPU6: $(percent(cpu.cpu6.inuse)
  CPU7: $(percent(cpu.cpu7.inuse)
  

Configuring menu items

RESULT: Per-core CPU usage in the context menu
(example for 8 cores)
