[FEAT] have more options for CPU and RAM graphs

[GM-Script-Writer-62850]

Describe the bug
CPU usage looks to include I/O wait time as copying files shows over 50% usage while top shows well under 10%

To Reproduce

Steps to reproduce the behavior:

1. Copy a large volume of files from 1 HDD to another HDD (not high speed SSD)
2. Look at applet shows massive CPU usage

Expected behavior

Shows actual CPU usage not operation wait time as usage

Hello,
That look like not an real bug but an improvement to allow exclude wait usage because vent in system monitor that usage is included in total CPU usage.

[GM-Script-Writer-62850]

There is something similar going on with ram usage

oh and the numbers on this one, just confuse me

5.0, 4.7, 4.4, and 4.6
i guess you can include or exclude shared, but at this point i am just confused

[orblazer]

Hum, i can add options for that too

And in you pictures for memory you have 3 different values because :

• htop: show application
• top/sleep : for used seem to show allocated
• system monitor & the widget : show physical

Note : with libksysguard its look like impossible to have allocated, i have only physical, application, buffer and cache

[GM-Script-Writer-62850]

sleep, what? oh i think i know that you are talking about
while [ 1 ];do sleep 1;clear;free -h;done

i would just note that showing allocated is not supported and only physical is supported to label it as physical ram usage eg:
Show physical memory monitor

Why are you using monitor/graph interchangeably under charts? probably best to call it a graph or a monitor, i vote for calling them graphs or charts (seems more logical ot me and it is the shorter word)

[GM-Script-Writer-62850]

Maybe you can make "[X] Show <select: physical/application/buffer/cache> memory monitor"

[orblazer]

Yes that an mistake to call it monitor.
For Show physical memory monitor this has disappear in 2.6.0 when i have switch to libksysguard.

I think i can add an selector like network for choose between none, physical, physical in %, application and application in %.

And maybe i can make the same behavior for CPU for allow to exclude wait.
NOTE: in future i think i should make an way to add and move each chart like the plasma system monitor app
