Easily create graphs from cli commands and view them in the terminal. Like the
watch command but with a graph of the output.
git clone https://github.com/aantn/smag.git cargo install --path .
Binaries for Mac, Windows, and Linux are available under Releases.
smag [shell_cmd] or
smag [cmd1] [cmd2] if you want to graph multiple commands at once.
You can control how often the graph updates with the
-n flag. You can also graph a derivative of the command's output using
smag can graph any command which outputs an integer or float. Any whitespace before/after the number is trimmed automatically.
Pull requests for more features or fixes are welcome.
- Graph number of processes:
smag "ps aux | wc -l"
- Graph number of bash processes and ssh processes as two separate lines:
smag "ps aux | grep ssh | wc -l" "ps aux | grep bash | wc -l"
- Graph number of running Kubernetes pods:
smag "kubectl get pods -A | grep Running | wc -l"
$ smag --help ✔ 2355 17:59:43 smag 0.5.0 Show Me A Graph - Like the `watch` command but with a graph of previous values. USAGE: smag [FLAGS] [OPTIONS] <cmds>... FLAGS: -d, --diff Graph the diff of subsequent command outputs --help Prints help information -V, --version Prints version information OPTIONS: -h, --history <buffer-size> Specify number of points to 'remember' and graph at once for each commands [default: 100] -n, --interval <polling-interval> Specify update interval in seconds.

smag was inspired and based on code from the wonderful gping tool by Tom Forbes
I also work on Robusta - better Prometheus based alerts for Kubernetes.
