Fehlerbehebung bei Leistungstests

Lesen Sie in der Liste der häufigen Fehler und Fehlerszenarien beim Debuggen nach.

Selector not found

Lösung: Aktualisieren Sie die UI-Selektoren und validieren Sie sie in Studio.

Package mismatch

Lösung: Aktualisieren Sie auf unterstützte Paketversionen und stellen Sie sie erneut bereit.

Robot connection issues

Lösung: Überprüfen Sie die Orchestrator-Konfiguration und die Anmeldeinformationen.

Debugging failed scenarios

Lösung: Verwenden Sie Anwendungsprotokolle, untersuchen Sie HTTP -Fehlerdetails und analysieren Sie Infrastrukturnutzungsdiagramme, um Ursachen zu isolieren.

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
• Verschlüsselung
  • 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.
• Authentication
  • 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).
• Architekturüberblick
  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 <your-eventhub-namespace>.<http://servicebus.windows.net|servicebus.windows.net> -Port 5671

2. Interpretieren Sie die Ergebnisse.
   • 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.
