Enhancement Please - Raspi CPU %

[Eddiiie]

Hello, Love your plug in. Is there any chance you could add one more item to it and that would be the current CPU usage of the Raspi?

I often wonder what the under-lying CPU usage is.

Thank you for your consideration.

[lazy-mode] what's the command to check CPU usage? [/lazy-mode] :)

Hi,

I found and tested a script on Octoprint / Raspberry Pi.

Taken from this URL: http://askubuntu.com/questions/450045/get-cpu-usage-in-command

It seems to work well.

Thank you for your consideration!

!/bin/bash

PREV_TOTAL=0 PREV_IDLE=0

while true; do

CPU=(cat /proc/stat | grep '^cpu ') # Get the total CPU statistics. unset CPU[0] # Discard the "cpu" prefix. IDLE=${CPU[4]} # Get the idle CPU time.

Calculate the total CPU time.

TOTAL=0

for VALUE in "${CPU[@]:0:4}"; do let "TOTAL=$TOTAL+$VALUE" done

Calculate the CPU usage since we last checked.

let "DIFF_IDLE=$IDLE-$PREV_IDLE" let "DIFF_TOTAL=$TOTAL-$PREV_TOTAL" let "DIFF_USAGE=(1000*($DIFF_TOTAL-$DIFF_IDLE)/$DIFF_TOTAL+5)/10" echo -en "\rCPU: $DIFF_USAGE% \b\b"

Remember the total and idle CPU times for the next check.

PREV_TOTAL="$TOTAL" PREV_IDLE="$IDLE"

Wait before checking again.

sleep 1 done

save it to cpu_usage, add execute permission chmod +x cpu_usage and run:

./cpu_usage

to stop the script, hit Ctrl+c

[Swiftnesses]

This would be an awesome feature!

[mtmello2003]

Agree.! could be great feature.

[Cosik]

@Eddiiie @Swiftnesses @mtmello2003 what do you think if we will give you possibility to execute custom command in shell and print results on Navbar?

[mtmello2003]

For sure will be the best option: let the user custom by them self.

[Eddiiie]

@Cosik That would be pretty cool and include the above script as a default?

[Cosik]

@Eddiiie I'm not sure if in first releases there will be something like "default"

[Cosik]

@Eddiiie Hi we prepared new feature for custom commands, please read this https://github.com/imrahil/OctoPrint-NavbarTemp/pull/52

[Cosik]

This could be done by custom command.
