Technical Tip: Secure SD-WAN Monitor Speed Test

To be able to view the populated output of Secure SD-WAN monitor in FortiAnalyzer, the configuration must be done as shown in this article: Technical Tip: FortiView Secure SD-WAN Monitor

Once it is configured, the SD-WAN monitor widget will show the result. However, the speed test of the SD-WAN member is not automatically populated. 

The widget will be populated when the speed test is done from the FortiGate. 

There are a few ways to generate the speed test. This article only describes about CLI speed test, which requires a valid SD-WAN Network Monitor license

To generate a speed test using the CLI speed test, on FortiGate: 

1. Download the server list from FortiCloud:

execute speed-test-server download
Download completed.

2. Verify the list:

execute speed-test-server list

3. Run the speed test using the CLI command:

execute speed-test <interface> <server> {Auto | TCP | UDP}

diagnose netlink interface speed-test <interface> <server> {Auto | TCP | UDP}

If the FortiGate does not have a valid SD-WAN Network Monitoring License, the following error will be generated:

FGT # execute speed-test
Failed to get a valid SD-WAN Monitoring (SWNM) license to execute speed test.
Command fail. Return code 25

4. SD-WAN logs will be generated. 

In FortiGate -> Log & Report -> System Event -> SD-WAN Events.

date=2025-11-17 time=10:01:46 eventtime=1763344906102560259 tz="+0800" logid="0113022938" type="event" subtype="sdwan" level="information" vd="root" logdesc="SD-WAN Bandwidth monitoring result" eventtype="WAN Speedtest Result" interface="port4" speedtestserver="FTNT_Global(154.52.16.34:5201)" mode="Auto" protocol="TCP" latency="8.54ms" upbandwidthmeasured="415598 kbps" downbandwidthmeasured="826680 kbps" timestamp="2025-11-17 10:01:46" msg="SD-WAN Bandwidth Monitoring Result"

5. In FortiAnalyzer -> FortiView -> SD-WAN -> Secure SD-WAN Monitor -> Speed Test will be populated.

The same command in the third step can be issued multiple times to plot multiple outputs in the widget. 

The list of options to generate a speed test is listed in the document SD-WAN Network Monitor service.

The speed test license is important for reporting SD-WAN security (SD-WAN Quality table)

If the FortiGate does not have the license, no results appear in the graph.
