How can I monitor network bandwidth & jitter using Performance monitoring?

We can monitor bandwidth, jitter, latency and packet loss using performance monitoring by monitoring the output of an executable. The command line CLI can be found here:

Speedtest CLI

Download the above tool and for the purposes of this How-to, we will copy it to C:\Tools on our EventSentry server. Then, open an elevated command prompt and navigate to C:\Tools and run: Speedtest.exe

This will prompt you to accept their licensing agreement.

Once that is completed, we can begin configuring EventSentry.

• Go to Tools > Embedded Scripts
• Click 'New' and then name the script 'speedtest.ps1'
• Then, click in the script content area and add the following script: $scriptOutput = (C:\Tools\speedtest.exe --format=json) | Out-String $jsonObj = $scriptOutput | convertFrom-Json $output = "" $output += [math]::Round($jsonObj.ping.jitter, 2) $output += ',' $output += [math]::Round($jsonObj.ping.latency, 2) $output += ',' $output += [math]::Round($jsonObj.packetloss, 2) $output += ',' $output += [math]::Round(($jsonObj.download.bandwidth/125000), 2) $output += ',' $output += [math]::Round(($jsonObj.upload.bandwidth/125000), 2) Write-Output $output
• In the 'Interpreter Field' select: powershell.exe -inputformat none -executionpolicy bypass –file
• Click "OK"
• Click on "Packages > System Health > Add" and name the package "Network Monitoring"
• Click on that package and click the drop-down under "Add" and select "Performance / SNMP"
• Click on "Performance / SNMP" in the "Network Monitoring" package and click the "+" to add a new counter:
  • Change frequency to "1 hour"
  • In the name field, add: Speedtest
  • Change "Windows Counter" to "Executable"
  • In the field next to "Executable", select "@speedtest.ps1"
  • Click "History & Trending"
    • Click "Record to database" and change to "3 hours" and select keep history
    • Click "Add" and select your database action
    • Click "OK"
• Click "Home > Save"

After 3 hours, you can view the collected data in the web reports by going to “Health > Performance > Status” and run the following query:
name:Speedtest
