Demo: https://andrewkroh.github.io/beats-playground/
It's a web UI to play with Elastic Beats processor configurations.
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. add_cloud_metadata,
add_docker_metdata, add_host_metadata, add_process_metadata, dns,
rate_limit, translate_sid).
Click the Share button to encode the current processor configuration and sample logs into the URL. The URL is automatically copied to your clipboard and can be shared with others. Note that the data is stored unencrypted in the URL.
The state is encoded as a JSON object with the following keys:
p- processors (YAML string)l- logs (text string)
This JSON is compressed with gzip and then base64 encoded. The URL format is:
https://andrewkroh.github.io/beats-playground/#s=ENCODED_STATE
To decode a shared URL, you can use CyberChef or the command line:
pbpaste | base64 -D | gunzipAlternatively, you can load configurations and sample logs from external URLs
by setting query parameters in the URL fragment (aka hash). It reads
load_processors and load_logs then loads the content from those URLs. The
format is:
http://localhost:8084/#?load_processors=PROCESSORS_URL&load_logs=LOGS_URL
Download a release binary and run it yourself. By default the binary listens for connections at http://localhost:8084/.
Run make and it will produce the beats-playground self-contained binary.
Building has several requirements like Go and yarn.
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.
