The application responds to HTTP requests with a message containing the VMs hostname. VNet is like a traditional network you would operate in your own data center. Clearly half of my requests are still being forwarded to the disconnected VM which is why they are timing out. This identity must be given appropriate permissions to the target resource for the experiment to run successfully. To observe the effect of the experiment Ill use the following piece of PowerShell - which will loop forever calling the load balancers public IP, outputting the message returned by the Node.js application and then sleeping for a second. Before Azure Chaos Studio can start modifying resources, those resources need to be enabled as targets and the specific faults were interested in need to be enabled as capabilities. Now we can actually run the experiment. If there is an error running your experiment, debugging information appears here.
