Résolution des problèmes de tests de performances

Consultez la liste des erreurs courantes et des scénarios d’échec de débogage.

Selector not found

Solution: Mettez à jour les sélecteurs d’IU et validez dans Studio.

Package mismatch

Solution: mettez à niveau vers les versions de packages prises en charge et redéployez.

Robot connection issues

Solution: Vérifiez la configuration et les informations d’identification d’Orchestrator.

Debugging failed scenarios

Solution: Utilisez les journaux des applications, explorez les détails des erreurs HTTP et analysez les graphiques d’utilisation de l’infrastructure pour isoler les causes profondes.

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 UiPath Robot uses this port to send performance metrics to the Performance Testing Service. If the port is blocked, metrics cannot be transmitted.

Context:

• Communication protocol
  • Protocol: AMQP (Advanced Message Queuing Protocol)
  • Transport: TCP
  • Port: 5671
• Encryption
  • All communication is secured using TLS 1.2.
  • Encryption in transit is enforced by Azure Event Hub.
  • Data at rest is encrypted using Microsoft-managed keys UiPath does not apply additional encryption at the application layer.
• Authentification
  • Authentication is handled using Shared Access Signature (SAS) tokens.
  • Tokens are issued and validated by Azure Event Hub.
  • Only authenticated clients can publish messages.
• Endpoint details
  • Endpoint format: *.<http://servicebus.windows.net|servicebus.windows.net>.
  • Service: Azure Event Hub (Microsoft Azure managed service).
• Présentation de l'architecture
  1. The Robot sends performance metrics using AMQP over TLS.
  2. Data is transmitted to Azure Event Hub.
  3. The Performance Testing service consumes the events.
  4. Metrics are processed and displayed in dashboards.

Solution:

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

   Test-NetConnection -ComputerName tmh-prod-tmh-eus-ehn.servicebus.windows.net -Port 5671

2. Interprétez les résultats.
   • 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>

Additional information:

• If port 5671 is blocked, performance metrics cannot be delivered, resulting in empty charts.
• If connectivity is successful but metrics are still missing, further investigation of Robot logs is required.
