Learn more about activating a broker VM with a NetflFlow Collector applet.
Ingesting records from external sources requires a Cortex XDR Pro per GB license.
To receive NetFlow flow records from an external source, you must first set up the NetFlow Collector applet on a Broker VM within your network. NetFlow versions 5, 9, and IPFIX are supported.
To increase the log ingestion rate, you can add additional CPUs to the Broker VM. The NetFlow Collector listens for flow records on specific ports either from any, or from specific IP addresses.
After the NetFlow Collector is activated, the NetFlow Exporter sends flow records to the NetFlow Collector, which receives, stores, and pre-processes that data for later analysis.
