SD-WAN chart for MOS scoring

An Audio MOS Score widget is added to FortiView > Monitors > Secure SD-WAN Monitor and FortiView > Monitors > SD-WAN Summary. These widgets display logs for the MOS (mean opinion score) of voice and video traffic.

MOS is a method to measure the impact network quality has on the quality of a voice call. It is the industry standard for measuring voice and video quality on a WAN link.

Note

The FortiGate version must be on version 7.2 or later and have the MOS codec and MOS threshold attributes defined for SD-wan health check in order for FortiAnalyzer to display information in the MOS scoring widgets.

To view the Audio MOS Score for individual devices:
  1. Go to FortiView > Monitors > Secure SD-WAN Monitor.
  2. Click Add Widget, and add the Audio MOS Score widget.

    The widget includes a line graph of the MOS score for different codecs for the selected device over a specified time period.

  3. Click a codec in the legend to make it appear/disappear on the chart.

    Greyed-out interfaces on the legend do not appear on the chart.

  4. Hover your cursor over the chart to see a summary at that point.

    This summary includes the MOS score and the VoIP quality at that time. VoIP quality is divided into levels based on MOS scoring: Excellent = 4.3 - 5.0, Good = 4.0 - 4.3, Fair = 3.6 - 4.0, Poor = 3.1 - 3.6, Bad = 2.6 - 1.0.

To view the Audio MOS Score across all devices:
  1. Go to FortiView > Monitors > SD-WAN Summary.
  2. Click Add Widget, and add the Audio MOS Score widget.

    The widget includes a line graph of MOS score per device on the network.

  3. Click a device in the legend to make it appear/disappear on the chart.

    Greyed-out devices on the legend do not appear on the chart.

  4. Hover your cursor over the chart to see a summary at that point.

    This summary includes the MOS score and the VoIP quality at that time.

To configure the FortiGate MOS codec and threshold in health check settings:
  1. Access the FortiGate CLI.
  2. Enter the following commands:

    config system sdwan

    config health-check

    edit <name>

    set server {string}

    set sla-fail-log-period {integer}

    set sla-pass-log-period {integer}

    set members <seq-num1>, <seq-num2>, ...

    set mos-codec [g711|g722|...]

    config sla

    edit <id>

    set link-cost-factor {option1}, {option2}, ...

    set mos-threshold {string}

    next

    end

    For example:

    config system sdwan

    config health-check

    edit "test_dc"

    set server "10.200.1.1"

    set sla-fail-log-period 15

    set sla-pass-log-period 15

    set members 1 2

    set mos-codec g722

    config sla

    edit 1

    set link-cost-factor latency jitter packet-loss mos

    set mos-threshold "2.0"

    next

    end
