seems like your nas is reporting wrong data. can you debug it?

julienlarivee commented 1 year ago

Hope there is all you need in it.

So truenas is reporting something really weird here. Idle 100% system 96%?

Try running mpstat or iostat to see if its problem with API or OS customization.

I got this while on heavy load:

tomaae commented 1 year ago

ok, so its problem with API itself. Nothing I can do there unfortunately.

julienlarivee commented 1 year ago

No problem. Thanks

tomaae commented 1 year ago

I plan to look into it further, but no promisses at all. I may open issue with IX, but they are super slow to fix API things.

Doesn't TrueNAS report CPU usage as 100% x Number of cores?

Thats how linux reports it, yes. But core and scale reports cpu usage inconsistently via API. Core always reports 100% as all cores. Scale did that too durring my development, but it seems to be different now. Possibly a bug in API.

tomaae commented 7 months ago

seems to be fixed in API
