Schema for a ChannelEvent — a detailed log entry recording HTTP request/response data for a channel request.

Event Types

:destination_response — emitted by Handler.persist_completion/2 on successful upstream proxy completion. Carries all fields (request/response details, latency, ttfb).
:error — emitted by Handler.persist_completion/2 on upstream proxy error, or by ChannelProxyPlug.record_credential_error/2 when destination credential resolution fails before proxying. Carries request fields and error_message; response fields may be nil.
