# Analyze an alert

To help you understand the full context of an alert, Cortex XDR provides the alert side panel and the causality view that enable you to quickly make a thorough analysis.

The causality view is available for XDR agent alerts that are based on endpoint data and for alerts raised on network traffic logs that have been stitched with endpoint data.

How to view alert analysis

1. From the **Alerts** page, locate the alert you want to analyze.
2. Click the alert and review the information in the alert side panel. If you want to see more information about the alert, click **Investigate** to open the alert investigation panel.
3. Right-click anywhere in the alert, and select **Investigate Causality Chain**.

   You can also view the causality chain over time using the **Timeline** view.
4. Review the chain of execution and available data for the process and, if available, navigate through the process tree.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-3.x/cortex-xdr-3.x-documentation/investigate-and-respond-to-incidents/investigate-alerts/triage-and-investigate-alerts/analyze-an-alert.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
