Every snapshot with an event is ignored by the housekeeping algorithms, and retained indefinitely in the database. There are four types of events:
- Alert - the project crossed an alert threshold in either directionQuality Gate - the status of the quality gate changed.
- Profile - the project quality profile used to analyze the profile project changed - either the profile was edited, or a different profile was used to analyze the project.
- Version - the project's version changed in the project pom.xml or analysis parameters.
- Other - an event was manually created on a snapshot. See Managing History, below.
