# cpupeek

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

![](samples/simple.gif)

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.

![](samples/per-pid.gif)

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`.

## Installation

```

wget https://github.com/raghu-nandan-bs/cpupeek/raw/main/release/cpupeek-$(uname -m) -O cpupeek \

 && chmod +x cpupeek

```

## Run

```

sudo ./cpupeek

```

## Options

```

sudo ./cpupeek --help

Usage of ./cpupeek:

  -cpu int

    	cpu to track (default -1)

  -interval duration

    	how often should the screen refresh? (default 1s)

  -log string

    	log file to write to (default "cpupeek.log")

  -pid int

    	pid to track (default -1)

  -show-items int

    	number of items to show in the barchart (default 20)

  -show-pids

    	display process id instead of their names.

  -true-scale

    	scale the barchart to 1s (y axis)
