# Viewing project activity

On the project activity page you can:

* View the full list of code scans performed on your project since it was created in SonarQube Server.
* Follow the evolution of the quality gate.
* See the changes in quality profiles.
* Discover when a given version of your code has been scanned.
* And others.

## Activity and history of a project

To see the activity and history of a project:

1. Retrieve your project. See [Retrieving projects](/sonarqube-server/user-guide/viewing-projects/retrieving-projects.md) for more information.
2. Go to **Activity**. The left sidebar contains the list of code scans performed on your project. The project snapshot purge policy is defined in [Housekeeping](/sonarqube-server/instance-administration/system-functions/housekeeping.md).
3. In **Filter events**, you can filter the scans list by event type. See [#event-types](#event-types "mention") for more information.
4. Graphs on the **Activity** page help you understand the evolution of up to three measures of your choice against each other. This allows you to compare project components and quickly spot the ones that represent the greatest risks. The **Activity** page offers several pre-defined visualizations, and you can also create custom visualizations with the metrics of your choice. For information, see [Monitoring metrics](/sonarqube-server/user-guide/code-metrics/monitoring-metrics.md).

In an issues graph, issues marked as false positive will still show as issues as long no new analysis run has been performed.
