# XDR Collectors

{% hint style="info" %}
Ingestion of log events larger than 5 MB is not supported.
{% endhint %}

Cortex Cloud provides an XDR Collectors (XDRC) configuration that is dedicated for on-premise data collection on Windows and Linux machines. The XDRC includes a dedicated installer, a collector upgrade configuration, content updates, and policy management. The XDRC is a data collector that gathers and processes logs and events from multiple sources. It leverages Elasticsearch Filebeat, a lightweight log shipper, to collect log data from various systems and applications. Additionally, Winlogbeat gathers Windows event logs, ensuring comprehensive visibility into Windows environments. These components facilitate centralized analysis, threat detection, and investigation across the Cortex Cloud ecosystem.

## 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-cloud-runtime-security/cortex-cloud-data-sources-and-connectors/generic-on-premise-data-collectors/xdr-collectors.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.
