Unless I’m using the wrong terms in my search it really seems like there’s no tool for Linux that can tell me what processes used the most CPU (typically this has a high correlation with energy usage) in the last hour or 24 hours.
Basically I want something like the Android battery usage app but for Linux.
I know that the system monitor app that’s included in KDE has a pretty extensive custom page tracking option.
You can open it up and then put in a whole bunch of like settings in a new page and track pretty much every metric that your computer has.
