Notable Event Types

On this page Carat arrow pointing down
Warning:
CockroachDB v21.1 is no longer supported as of November 18, 2022. For more details, refer to the Release Support Policy.

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.

Cluster-level events

Events in this category pertain to an entire cluster and are not relative to any particular tenant.

In a multi-tenant setup, the system.eventlog table for individual tenants cannot contain a copy of cluster-level events; conversely, the system.eventlog table in the system tenant cannot contain the SQL-level events for individual tenants.

Events in this category are logged to the OPS channel.
