Azure Connectivity Toolkit (AzureCT)

Overview

The Azure Connectivity Toolkit (AzureCT) is a PowerShell module and collection of server side web pages which can test, generate, collect, store, and display performance and availability statistics of the network between you and Azure. The two main areas of functionality are:

  • Network Performance Testing: The Get-LinkPerformance command runs a series of iPerf3 bandwidth load tests while concurrently doing a TCP ping to show latency under various loads.
  • Network Availability Testing: The Get-AzureNetworkAvailability command runs pings and traceroutes over an extended period of time to show end to end availability and hop latency.

Link Performance

1

This collection of PowerShell commandlets will download required files to run the Get-LinkPerformance command which runs a series of iPerf load tests and PSPing TCP pings concurrently between a local source and a remote host running iPerf3 in server mode. Six tests of increasing load are performed and results are output at the conclusion of the test. This testing is designed to show link latency and bandwidth capabilities under various conditions.

Requirements: Link Performance testing requires a local Windows machine from which PowerShell is run and a remote host, either Linux or Windows, running iPerf3 and listening on an admin port either 22 for Linux or 3389 for Windows.

To install and test Link Performance follow the instructions here: Performance Testing Instructions

Link Availability

0

This collection of server side web pages and local PowerShell that will generate, collect, store, and display availability statistics of the network between you and a newly built Windows VM in Azure.

It is designed to provide an indication, over time, of the link between a Virtual Machine in Azure and an on-premise network. While the focus is on network availability, the test is done from a PC client to an IIS server in Azure. This provides a view into the availability of an end-to-end scenario, not just a single point or component in the complex chain that makes up a VPN or an ExpressRoute network connection. The hope is that this will provide insight into the end-to-end network availability.

Requirements: Link Availability testing requires a local Windows machine from which PowerShell is run and a newly built remote Windows VM running IIS and a small web application.

To install and test Link Performance follow the instructions here: Availability Testing Instructions

While the author is an employee of Microsoft, these tools are provided as my best effort to provide insight into the connectivity between an on-premise network and an Azure endpoint. See the Support and Legal Disclaimers below for more info.

Removing the Azure Connectivity Toolkit

Once testing is complete the Azure VM can be deleted to avoid unnecessary Azure usage (and associated charges) and all local files can be deleted. The only files on the local machine are the PowerShell module files copied from GitHub, iPerf and PSPPing files in the C:\ACTTools directory (if Install-LinkPerformance was run), and potentially three XML files (if Get-AzureNetworkAvailability was run) in the Local Client PC %temp% directory.

To ensure 100% removal of all artifacts from the Azure Connectivity Toolkit perform the following step:

  1. Run the Remove-AzureCT command from PowerShell. This will remove the PowerShell module and any local data files.
