The hub must use a performance SLA with the same criteria as the spoke's health check. The spoke's health check is using ping (protocol ping) and measuring latency (link-cost-factor latency). For the hub to use the data sent by the spoke, its performance SLA must be configured to measure the same metrics. If the hub is looking for jitter or packet loss, it will not use the latency data sent by the spoke.

When a spoke sends embedded health data, the hub FortiGate must be configured to receive and use it. This is done by setting set embedded-measure accept within the performance SLA configuration on the hub. This setting explicitly tells the hub to trust and use the performance metrics received from the remote FortiGate (the spoke). Without this setting, the hub will likely ignore the embedded health data and rely on its own health checks, which could lead to incorrect traffic prioritization.
