probe-dictionary

A tool that makes the Telemetry probe data in Firefox more discoverable and searchable.

This front-end allows answering questions like

• "do we have any probes in Firefox 55 that tell us about tab usage?"
• "which Firefox versions is this probe in anyway?"

To achieve this, it uses data extracted by the probe-scraper project. This pulls probe registry files (Histograms.json, Scalars.yaml, Events.yaml) from different Firefox versions together into one dataset. Also, probes outside of Histograms.json - like the CSS use counters - are included in the output data.

Currently this supports:

• release, beta & nightly channels
• major releases only
• all probes registered in separate files (histograms, scalars, events)
• some select environment data points (more to come)
