How long are VM/CT resource usage data kept retrievable?

[iBug]

I'm managing a cluster of LXC containers with PVE 6.1. It's nice to be able to watch resource from the web interface, however I can't find how to horizontally scroll the graph, so I could only see resource usage in the last 70 minutes. Is there any way to get older usage history, preferably a day or two?

You can select the time spawn at the top right. It is a RRD database, and you can select from one hour to one year.
