Easily create graphs from cli commands and view them in the terminal. Like the watch command but with a graph of the output.

I also work on Robusta - a Kubernetes monitoring and automation platform. It makes your Prometheus alerts better.

Joe Schaefer (joesuf4) forked this repo to make it zsh -ic friendly, so his https://github.com/joesuf4/home/tree/wsl rcfiles work cleanly as command-line args to swag.

• Install 💿
• Usage

git clone https://github.com/aantn/smag.git
cargo install --path .

Binaries for Mac, Windows, and Linux are available under Releases.

Just run 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 -d.

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
