Technical Tip: Monitoring performance SLA reduced in the GUI from 10 minutes to 1 minute

A change has been made to the default behavior of the Performance SLA history.

Before FortiOS v7.4.8, a 10 minute historical graph was shown under Network -> SD-WAN -> Performance SLAs.

On FortiOS v7.4.8 and higher, this 10 minute history can be seen only through the CLI. The GUI will show only a 1 minute history graph.

This is the new default behavior and cannot be changed.

The 10 minute history can be viewed in the CLI. First, check the name of the health-check and the sequence.

diagnose sys sdwan health-check
Health Check(Default_DNS:(
Seq(2 port1): state(alive), packet-loss(0.000%) latency(7.820), jitter(0.364), mos(4.400), bandwidth-up(9999998), bandwidth-dw(9999941), bandwidth-bi(19999939) sla_map=0x1
Seq(3 port2): state(alive), packet-loss(0.000%) latency(13.273), jitter(0.589), mos(4.397), bandwidth-up(9999998), bandwidth-dw(9999994), bandwidth-bi(19999992) sla_map=0x1
