Overview

Provides instructions to configure path monitoring in Firewall Management Center (FMC) to collect link performance metrics and guide intelligent egress selection for Direct Internet Access (DIA) traffic.

The PBR policy relies on flexible metrics, such as round trip time (RTT), jitter, mean opinion score (MOS), and packet loss of the interfaces to identify the best routing path for its traffic. Path monitoring collects these metrics on the specified interfaces. On the Interfaces page, you can configure interfaces with settings for path monitoring to send the probes for metrics collection.

Select Devices > Device Management and click Edit (edit icon) for the threat defense device (NGFWBR1).
