Incident timelines are an important part of record keeping for incidents. Timelines can show executives and external viewers what happened during an incident, and which steps were taken for it to be resolved.

2. On the left sidebar, select Monitor > Incidents.
3. Select an incident.
4. Select the Timeline tab.

When labels change (Experiment)

Introduced in GitLab 15.3 with a flag named incident_timeline_events_from_labels. Disabled by default.

FLAG: On self-managed GitLab, by default this feature is not available. To make it available per project or for your entire instance, ask an administrator to enable the feature flag named incident_timeline_events_from_labels. On GitLab.com, this feature is not available. This feature is not ready for production use.

A new timeline event is created when someone adds or removes labels on an incident.

When creating an event using the form or editing it, you can specify incident tags to capture relevant incident timestamps. Timeline tags are optional. You can choose more than one tag per event. When you create a timeline event and select the tags, the event note is populated with a default message. This allows for a quick event creation. If a note has already been set, it isn't changed. Added tags are displayed next to the timestamp.
