Elixir event reference

Every event the Honeybadger Elixir package sends to Insights when instrumentation is enabled: Phoenix requests and LiveView lifecycles, Ecto queries, Oban jobs, Absinthe GraphQL operations, Ash actions, and Finch and Tesla HTTP client requests. Each entry lists the event's fields with their types, and links to its raw JSON Schema.

18 events emitted by honeybadger-elixir.
