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.
A tool like Librenms will give you this.
It might but it also looks really advanced. I’m hoping to get stats on just one machine and not really monitor my entire infrastructure (which ain’t much).
Then a tool like netdata may be the thing.
