@Giamma1963

I had to change the command in the Free Memory exec node to: free | grep Mem | awk '{printf("%.2f"), $4/$2 * 100.0}'

I also reversed the red and green gradient on the gauge to better caution me how little memory my RPi3 had left :P

Hi,

first of all - thanks a lot for this Flow and Dashboard.

I run this since I started with NodeRed in 2020. Its running as a instance of ioBroker on an RaspberryPi 4b with 8GB RAM. OS was Debian Buster. - Everything works good and I did some modifications to prevent unwanted shutdown/restart (I saw, you did something like that above in another way).

Now I had trouble during upgrading my system from Node.js 12 to 14. Something went wrong and I had to reinstall the whole system.
After restore the backup and reinstall all missing NodeRed-Nodes it runs nearly as known.
Only in your monitoring the CPU-Load and the Free Memory is not showing anything. CPU-Temperature and Used Disk-Space ist OK.
During the new installation I changed from Linux10/Debian Buster to Linux11/Debian Bullseye. Is it possible, that the commands you used in the exec-nodes are not running with bullseye?

Best regards
Wolfgang
