Monitoring your system health with HTOP (big.LITTLE)

Recommended Posts

Just In case anyone is interested I have pushed HTOP 2.2.1 to github, so it is possible to monitor big.LITTLE cores in real-time.

You can view the big.LITTLE in action, Vcore, Cpu thermal throttling and Cpu frequency for each big or LITTLE core.

 

HTOP is a nice console graphical tool for system-monitor, process-viewer and process-manager.

DEB package and source code in case you want to extend or fix things.

Be aware the process list and task can be very intrusive if you want to monitor many things at once.

It has been tested on NanoPi M4 (thanks to FriendlyElec for the samples) but should work on any SBC just adjust the Vcore path for different kernel version.

... and I have build it and pushed to Armbian stable repository (Stretch, Xenial and Bionic; armhf+arm64). First boot scripts also creates CPUfreq config based on CPU count. More can be added if there is an interest ... Package can be installed via apt update and upgrade while auto config feature will work only on self made images.

big.LITTLE has a policy for each cluster so I pushed some changes to display CPU Temp, CPU Freq, and CPU V-core for each cluster instead of CPU Freq for each CPU.

Added a branch: rk3399 so it does not break things, you may need to review the boot script if one would like to know CPU temp for big and for LITTLE cores.htop.png.0f8f82110c040bb7b765d71010f93032.png
