What is "unraid-api" process?

[icodesign]

I notice my unraid server continuously have about 50% CPU load (not sure if it's common) and "unraid-api" is always the top one. Any guidance on what this for and how I can lower the CPU load.

 

See attached screenshot.

That's our API that's installed when you install the my servers plugin.
I'd expect it to be using a lot less CPU usage though.

Could you confirm you're on the latest version of the plugin and can I get a copy of your diagnostics.zip ?

[icodesign]

Thanks for replying. The plugin seems to be up-to-date and attached diagnostics.zip.

Thank you.

In a terminal on that server can you run "unraid-api restart" and just see if that makes any difference.

This isn't related to your issue, but I'd recommend going to Settings -> Scheduler -> Mover Settings and disabling "Mover logging". That is only meant to be on if you are troubleshooting issues with mover.

Interesting. I just checked my settings and "Mover logging" is already disabled.

Restarting seems to work for now. I need keep monitoring to see if it goes up again. Thank you!

Hi just had the same issue with Unraid API. The load was at 25 % (~12% by Unraid API). 

After the restart command the load is just going down again. 

 

 

Any knowledge about this? 

 

Regards

That does look high compared to what I’d expect.

I will have a look in parallel. If the load is again high I will not restart the API for some test.

Just had a look into Grafana. It looks like that is a slow process and some process is just need more resource over the time. You can see the increase here:

Guess we should add a cron job to restart the process? LOL...

That was also my idea.  But this is just a workaround

I'm not sure if this is related to the OP issue, but I had an issue with "My Servers" constantly backing up the flash every minute.

Flash backup initialization solved that.

I kept watching the server, found UNRAID-API taking up CPU resources, and this was in the log.

I stop the flash backup and started it again on 14:26 through the GUI, and so far all is OK.
