Analysis CPU and memory usage per installed app?

Hello,

I have running nc 19.0.2 by a external hoster. I pay this hoster per CPU and memory used.
Last month I must upgrade my memory as additinal 4GB.

It is possible to analyse per installed app how many CPU and memory is used? By my hoster I see only how many used the whole nextcloud instance, but not detailed per app.

Thanks
Michael
