# Data Inventory

The **Data Inventory** provides a dynamic view of the data sources that are ingesting data into Cortex XSIAM. You can see breakdowns of data ingestion by data source, ingestion rates, trends, and prevented events.

You can access the dashboard from the **XSIAM Command Center** by clicking a data source, the number of **Endpoints** or **VM Brokers/XDRCs**. The **Data Inventory** includes incoming data sources and key performance indicators. The following table describes each of these sections:

<table><thead><tr><th width="162">Section</th><th>Details</th></tr></thead><tbody><tr><td>Data sources</td><td><p>Data sources are broken down into categories. Depending on the selected data source, the dashboard opens the relevant category. You can expand a category to see details of individual data sources and hover over a data source to see more details. You can also click on a data source to link to a drill down view, filtered by your selection:</p><ul><li>Connected endpoints</li><li>PANW integrations</li><li><p>3rd party data sources</p><p>Only registered Cortex XSIAM data sources are displayed in this view. To register a data source, install the relevant integration in the Marketplace.</p></li></ul></td></tr><tr><td>Key performance indicators</td><td><ul><li><p><strong>Event Ingestion</strong> and <strong>Data Ingestion</strong> display the amount of data and events ingested during the time frame and the ingestion rate.</p><p>The trend percentages for the key performance indicators are calculated by comparing the totals from the current time frame with the totals of the previous time frame. An arrow indicates whether the rates are rising or falling in comparison to the previous time frame's total.</p></li><li><strong>Collection errors</strong> displays the number of collection errors that occurred in the time frame. Collection errors occur when integration instances that fetch data have an error status.</li></ul><p>Click on the key performance indicators to drilldown to dedicated pages for further investigation.</p></td></tr></tbody></table>

## 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-xsiam/detect-investigate-and-respond-to-threats/monitor-dashboards-and-reports/dashboard-reference/command-center-reference/xsiam-command-center/data-inventory.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.
