CPU Graph showing greater than 100%

[egeexyz]

I'm running Cockpit on my server where I run a small cluster of Docker containers. The resource usage I am seeing in Cockpit does not match the usage which Docker is reporting, nor the usage that htop is reporting.

Here's a set of screenshots of what I am seeing - https://imgur.com/a/k5km6

The only way the Cockpit numbers would make sense is if 100% = 1 full core. But that is misleading at best. If that is the case, I would consider this a bug as that is a relatively uncommon way of calculating CPU usage.

Use case - I've got a 12 core CPU, so it shows the max usage at 1200%? That is just silly.

Yes. that's the idea. I think it comes from the 'top' command, which defaults to this ("Solaris" mode) for %CPU of individual processes.

I agree.

(Oh, a better place to report this is https://github.com/cockpit-project/cockpit/issues. Is there a way to move issues on Github? We can cope either way, of course.)

Oh shoot, I didn't realize this was the issue tracker for the website.. I'll repost this issue on the issue tracker you posted above. Thanks!
