Events in Sonar are used to flag some snapshots of a project. Those events can then be displayed for instance by the Timeline widget, the events widget or used to configure the differential views. Out-of-the-box there are four categories of events automatically handled by Sonar:

• Profile: to flag a snapshot as soon as a new quality profile or an updated quality profile is used to analysis this snapshot
• Version: to flag a snapshot as soon as the version of the project evolved
• Alert: to flag a snapshot as soon as an alert has been fired on this snapshot
• Other: to allow a user to manually flag a snapshot without having to define its own event category

Managing Categories of Events

Beyond those four default categories, it is possible to create/update/delete some new ones within Sonar. In order to do so, sign in, go to configuration at the top right of the page and select Events Category in the left menu:

Managing (creating, renaming, deleting) Events

To do such kind of operations, sign in with project administration rights, go to the project area and click on the Configuration > History page. All past quality snapshots on this project are displayed and for each quality snapshot, if some events exist there are automatically displayed:

Events on "Quality Profile" and "Alert" categories can't be updated whereas it's possible to create/rename or remove events on "Version" or home made categories. When a project contains some sub-modules any operation on events is automatically propagated to sub-modules.
