cpupeek

Gives visual representation of how much CPU processes are using, and other aspects.

Supports two selectors:

• CPU
• PID

That is, we can select a CPU to inspect runtime of each process in it.

or we can chose a process and see what CPUs it gets scheduled on, and how long its been running in each of these CPUs.

By default, all CPUs and all PIDs are selected, and display is grouped by process.

if a CPU is selected, display will be grouped by processes.

if a Process is selected, display will be grouped by CPUs it has been running on.

This app uses ebpf.
