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.

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.

schema_descriptor

An event of type schema_descriptor is an event for schema telemetry, whose purpose is to take periodic snapshots of the cluster's SQL schema and publish them in the telemetry log channel. For all intents and purposes, the data in such a snapshot can be thought of the outer join of certain system tables: namespace, descriptor, and at some point perhaps zones, etc.

Snapshots are too large to conveniently be published as a single log event, so instead they're broken down into SchemaDescriptor events which contain the data in one record of this outer join projection. These events are prefixed by a header (a SchemaSnapshotMetadata event).

Zone config events

Events in this category pertain to zone configuration changes on the SQL schema or system ranges.

When zone configs apply to individual tables or other objects in a SQL logical schema, they are relative to a particular SQL tenant. In a multi-tenant setup, copies of these zone config events are preserved in each tenant's own system.eventlog table.

When they apply to cluster-level ranges (e.g., the system zone config), they are stored in the system tenant's own system.eventlog table.

Events in this category are logged to the OPS channel.

Field	Description	Sensitive
ResolvedOldConfig	The string representation of the resolved old zone config. This is not necessarily the same as the zone config that was previously set -- as it includes the resolved values of the zone config options. In other words, a zone config that hasn't been properly "set" yet (and inherits from its parent) will have a resolved_old_config that has details of the values it inherits from its parent. This is particularly useful to get a proper diff between the old and new zone config.	yes
