Notable Event Types

Certain notable events are reported using a structured format. Commonly, these notable events are also copied to the table system.eventlog, unless the cluster setting server.eventlog.enabled is unset.

Additionally, notable events are copied to specific external logging channels in log messages, where they can be collected for further processing.

The sections below document the possible notable event types in this version of CockroachDB. For each event type, a table documents the possible fields. A field may be omitted from an event if its value is empty or zero.

A field is also considered "Sensitive" if it may contain application-specific information or personally identifiable information (PII). In that case, the copy of the event sent to the external logging channel will contain redaction markers in a format that is compatible with the redaction facilities in cockroach debug zip and cockroach debug merge-logs, provided the redactable functionality is enabled on the logging sink.

Events not documented on this page will have an unstructured format in log messages.
