> For the complete documentation index, see [llms.txt](https://cortex-docs.paloaltonetworks.com/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://cortex-docs.paloaltonetworks.com/cortex-xdr-3.x/cortex-xdr-3.x-documentation/investigate-and-respond-to-incidents/investigate-alerts.md). # Investigate alerts Alerts help you to monitor and control the security of your system framework by alerting you to security risks in your framework. Cortex XDR generates alerts from the following: * Rules that you set up, such as BIOC, IOC, correlation rules, etc. * Agents * Firewalls * Analytics * Integrations Integrations enable you to ingest events, such as phishing emails, SIEM events, from third party security and management vendors. You might need to configure the integrations to determine how events are classified as events. For example, for email integrations, you might want to classify items based on the subject field, but for SIEM events, you want to classify by event type. --- # Agent Instructions This documentation is published with GitBook.

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.md?ask=&goal= ``` `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.
