Homebrew Environment Configuration Events (30 days)

Period: 2026-09-29 to 2026-10-29, with 104,569,019 reported events across 162 variables.

Source and definitions

Source: Homebrew’s InfluxDB analytics, with notice and an opportunity to opt out before events are sent; JSON and collection details.

Category: Reported environment variable, not a unique user or machine.

Events: One randomly sampled configuration variable per invocation of selected common commands; values are never recorded.

Default value: The documented default, not a user’s value.

Non-default / Default / Unset: Sampled events in each state, with variables exported by Homebrew itself counted as unset.

Non-default %: Non-default events as a percentage of this variable’s sampled events.

Unreported events are excluded; counts do not establish unique users or successful formula installations.
