CPU temperature monitoring

[Feek]

So far I have entered „sensors“ into the terminal from time to time.

Now I found out that pmcputemp is already included in Fatdog.
It doesn´t appear in the tray automatically.
I can launch it only via terminal (I created a simple script in /root/startup with text: <urxvt -e & pmcputemp> and it works).

The temperature values displayed simultaneously by pmcputemp in the tray and the „sensors“ in terminal seem to be different.
Which one is closer to reality?

I don't use pmcputemp, because there's already:

Right-click the LxQt-panel -> Manage Widgets -> + -> Sensors

It supports multiple sensor readings, through libsensors, just like the sensors command.

Greetings!

@JakeSFR ,

I didn't know about this.

Very nice ! Thank you.

I also don't use pmcputemp from today .

This is a extract of the code I use to show a temperature icon in the tray of my bespoke containers. Generates its own .svg icon. Updates every 5 seconds (sleep 5 in _temp() function)

Code: Select all

#!/bin/bash

# Requires 'sit' to have been installed (from gslapt/repo) as that is used
# to stuff the temperature icon into the tray

REDTHRESHOLD=66 # CPU temperature at which icon colour turns red

_tempsvg() {                                               # cpu temperature .svg
