Question regarding per process load / energy consumption

[step21]

Hey,

do you think it is possible to do usage load per process, like powermetrics is doing, either directly or by calculating oneself? Powermetrics and esp activity monitor has utilization per process, and then energy usage per process which would be even nicer. Right now I found that neither macmon or the other competitiors provide this. Ideally it would be as simple as dividing average power draw of one measurement by 100 and then multiplying by % of cpu/gpu utilization. But probably it is way more complicated? Ideally it would be awesome if it could be added to macmon, but I understand if this is of lesser concern. I also know that this data is not totally accurate, but for comparison on the same system I assume it is good enough for my use case.
What do you think?

@step21 Hi. I haven't looked at where powermetrics gets the information from for each process. In general, macOS has other means to get this information: https://blog.mozilla.org/nnethercote/2015/08/26/what-does-the-os-x-activity-monitors-energy-impact-actually-measure/.

In which mode do you need this data: TUI or pipe?

[step21]

Hi, yeah I also found this blog post. Unfortunately, it's quite old, and the information from activity monitor is in any case not available in powermetrics from what I can tell. (and I would want to have some programmatically query-able metrics)
I would want it either in pipe or in my external lib. I was mainly trying to brainstorm if such a measurement makes sense or if I'm missing something. If you want to add it to tui, also great though.
