Troubleshooting Missing PT Metrics (Port 5671 Blocked)

If Performance Testing charts are empty or metrics are missing, it may be caused by a firewall blocking Port 5671, which is required for communication with Azure Event Hub. The Robot uses this port to send performance metrics to the PT Service. If the port is blocked, metrics cannot be transmitted.

Solution:

1. Run the following command on the Robot machine using Windows PowerShell.

   Test-NetConnection -ComputerName <http://tmh-prod-tmh-eus-ehn.servicebus.windows.net|tmh-prod-tmh-eus-ehn.servicebus.windows.net> -Port 5671

2. 解释结果。
   • Port is open (Expected). This means the Robot can successfully communicate with Azure Event Hub.

     TcpTestSucceeded : True

   • Port is blocked. This indicates that the firewall is blocking outbound communication on Port 5671.

     WARNING: TCP connect to (x.x.x.x : 5671) failed

     TcpTestSucceeded : False

     Allow the following outbound connection (firewall rule).

     ProtocolPortDestinationTCP5671*.<http://servicebus.windows.net|servicebus.windows.net>
