If I have more than 8 threads, I'll use the composite CPU chart instead. Also, I have to tell it to ignore veth, vnet, and virbr network interfaces, since I run virt-manager on the box as well.

I think perhaps I’m old school, but I’ve been using xosview with a patch that shows ccx utilization (on AMD) instead of per core. Treats me pretty well, but it’s a very unloved project.

Do you have a link to that patched version?

Just scale down the chart size. For my 16 core system each CPU chart is just 5px high, it works great because you still have the horizontal indicators.

You can pick and choose which devices are important to monitor, and you can combine all the CPU cores into one chart. That's what I do anyway.
