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`](cockroach-debug-zip.html)" + `
and ` + "[`cockroach debug merge-logs`](cockroach-debug-merge-logs.html)" + `,
provided the ` + "`redactable`" + ` functionality is enabled on the logging sink.

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