Note

Agents with Cortex XDR Pro per Endpoint apply limits and filters on network, file, and registry logs. To expand these limits and filters, the Extended Threat Hunting Data (XTH) add-on must be purchased.

The tables below note whether specific logs require the XTH add-on.

Metadata Collected for Cortex XDR Agent Alerts

When the Cortex XDR agent raises an alert on endpoint activity, the following metadata is sent to the server:

Field	Description
Absolute Timestamp	Kernel system time
Relative Timestamp	Uptime since the computer started
Thread ID	ID of the originating thread
Process ID	ID of the originating process
Process Creation Time	Part of the process unique ID per boot session (PID + creation time)
