# Activity and history

The **Activity** page offers you the ability to see the evolution of project measures over time.

Go to **Projects** > *Your Project* > **Activity** to view a comprehensive list of the analyses on a file for a project (subject to [housekeeping](https://docs.sonarsource.com/sonarqube-server/8.9/instance-administration/housekeeping "mention")). Graphs on the **Activity** page help you understand the evolution of up to three measures of your choice against each other. Graph mouseovers show the measure values and events associated with particular analyses.

## Events <a href="#events" id="events"></a>

There are four types of events:

* Quality Gate: The status of the [quality-gates](https://docs.sonarsource.com/sonarqube-server/8.9/user-guide/quality-gates "mention") has changed.
* Profile: The [quality-profiles](https://docs.sonarsource.com/sonarqube-server/8.9/instance-administration/quality-profiles "mention") used to analyze the project has changed. Either the profile was edited, or a different profile was used to analyze the project.
* Version: The project’s version changed.
* Other: An event was manually created on a snapshot. See [managing-project-history](https://docs.sonarsource.com/sonarqube-server/8.9/project-administration/managing-project-history "mention") for more information.

Events are also shown on the front of the **Project Homepage**. See the documentation on the [project-page](https://docs.sonarsource.com/sonarqube-server/8.9/user-guide/project-page "mention") for more details.
