# Triage and investigate alerts

All alerts are displayed on the **Alerts** page. Use the following steps to investigate and triage the alert:

1. Review the data shown in the alert such as the command-line arguments (CMD), process info, etc.
2. Analyze the chain of execution in the causality view.

   When the app correlates an alert with additional endpoint data, the **Alerts** table displays a green dot to the left of the alert row to indicate the alert is eligible for analysis in the causality view. If the alert has a gray dot, the alert is not eligible for analysis in the causality view. This can occur when there is no data collected for an event, or the app has not yet finished processing the EDR data. To view the reason analysis is not available, hover over the gray dot.
3. If deemed malicious, consider responding by isolating the endpoint from the network.
4. Remediate the endpoint and return the endpoint from isolation.

## 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.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.
