Any recommendations for low-impact tools I can use to better understand the activity of expired processes?

Sar?
Yeah, so this is the best one I’ve seen so far.
I’ve just installed it, but I’m stumped on the documentation on how to find the name of a high-load process from 10 mins ago.
Install and start the monitoring
sudo pacman -S sysstat sudo systemctl {enable,start} sysstatFind what processes were running 10 minutes ago
(first wait 10 minutes)
sar -P ALL -f /var/log/sa/sa$(date +%d -d '10 minutes ago')nothing happens.
fyi, systemctl disable/enable has a --now flag
Sudo cpupower -c all frequency-set --max 0.8GHz No more spikes 😎👍👌
That’d just prolong a mild spike instead
Sounds like atop is exactly what you need.
