Administrator Guide

You can monitor the activity of any Cortex XSIAM Broker VM that you manage.

The Cortex XDR agent logs entries for events that are monitored by the Cortex XDR agent, and hourly reports the logs back to Cortex XSIAM. Cortex XSIAM stores the logs for 365 days. To view the XDR agent logs, select Settings Agent Auditing.

To ensure you and your colleagues stay informed about agent activity, you can Configure Notification Forwarding to forward your Agent Audit log to an email distribution list, Syslog server, or Slack channel.

You can customize your view of the logs by adding or removing filters to the Agent Audits Table. You can also filter the page result to narrow down your search. The following table describes the default and optional fields that you can view in the Cortex XSIAM Agents Audit Table:
