Beats Playground

Demo: https://andrewkroh.github.io/beats-playground/

It's a web UI to play with Elastic Beats processor configurations.

How it works

I reused the processors code Elastic Beats and compiled it into a WebAssembly binary that is loaded by the browser. All processing happens in the browser so none of your sample/test logs ever leave the browser.

Because of browser limitations, processors that require OS resources (filesystem, sockets) are not included (e.g. dns, translate_sid, rate_limit, add_docker_metdata).

It will load configurations and sample logs from URLs if you set the appropriate query parameters in the URL fragment (aka hash). It reads load_processors and load_logs then loads the content from those URLs. This can be used to share examples. The format is:

http://localhost:8084/#?load_processors=PROCESSORS_URL&load_logs=LOGS_URL

Self-hosting

Download a release binary and run it yourself. By default the binary listens for connections at http://localhost:8084/.

Building

Run make and it will produce the beats-playground self-contained binary. Building has several requirements like Go and yarn.

Releasing

Pushes to master automatically update the demo page host by Github Pages. The commit ID can be verified by looking at the browser's console.

Git tags automatically trigger uploads of binaries to the Github release page.
