# Activity and history

The Activity page in SonarQube Server 10.5 offers you the ability to see the evolution of project measures over time.

{% hint style="info" %}
**For AI agents:** You're in the SonarQube Server 10.5 documentation. For a list of all 10.5 pages, see the [SonarQube Server 10.5 page index](https://3691828591-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Feu7dHWcqP9Cr3eUAzwWg%2Fuploads%2FjUvEoDEUUE0rAURT5wZJ%2Fsonarqube-server-10.5-llms.txt?alt=media). For the whole site, see the [page index](https://docs.sonarsource.com/llms.txt) or the [full text](https://docs.sonarsource.com/llms-full.txt). For another version, replace 10.5 in the URL with that version. The [latest version](https://docs.sonarsource.com/sonarqube-server/) has no version number in its URL.
{% endhint %}

The **Activity** page offers you the ability to see the evolution of project and [Applications](/sonarqube-server/10.5/user-guide/applications.md) measures over time.

Go to **Projects** > *Your project or application* > **Activity** to view a comprehensive list of the analyses on a file for a project (subject to [Housekeeping](/sonarqube-server/10.5/instance-administration/housekeeping.md)).

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>

The following table groups the events you can find on the **Activity** page:

| **Event**                        | **Description**                                                                                                                                                                                                                                            |

Events are also shown on the project or application’s **Overview** page.

On the **Overview** page, each analysis snapshot shows a measure variation compared to the previous analysis regarding number of issues, coverage, and duplications.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.sonarsource.com/sonarqube-server/10.5/user-guide/activity-and-history.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
