High CPU usage

[Eixen]

Hi Cloudron-Team,

something i have high cpu usage on my server, and i can't figure out which processes are responsible for that. Seems to me that the specific apps take just a little part of it. How can i take a deeper look into it? I will post my screenshot fromt the monitoring. Thank you!

Hello @eixen

You can connect to your server via ssh and run the following command:

docker stats

This will show you a live view like this:

That could help to find out what is causing the load.

Thanx! But how can i identify the application container, because the name is just a ssid. And it is just possible to measure for now, right? Because i would like to see what happened hours ago, when i had high cpu usage, fx in the night.

2nd column shows app ID.
If you have Cloudron CLI installed, cloudron list will show app ID and app URL.
Or you can iterate through apps in the dashboard looking for the ones which have that ID

For detailed historic view you would need a monitoring solution like Zabbix https://ca.cloudron.io/app/io.cloudron.zabbix
With that you'd have meaningful insights of the past.
