Incident tags

Version history

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.

Formatting rules

Incident timeline events support the following GitLab Flavored Markdown features.
