Solución de problemas de pruebas de rendimiento

Consulta la lista de errores comunes y escenarios fallidos de depuración.

Selector not found

Solución: actualice los selectores de IU y valide en Studio.

Package mismatch

Solución: actualice a versiones de paquete compatibles y vuelva a implementar.

Robot connection issues

Solución: comprueba la configuración y las credenciales de Orchestrator.

Debugging failed scenarios

Solución: utiliza los registros de la aplicación, profundiza en los detalles del error HTTP y analiza los gráficos de uso de la infraestructura para aislar las causas raíz.

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
  • Cifrado
    • 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.
  • Autenticación
    • 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).
  • Información general sobre la arquitectura
    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 5671Test-NetConnection -ComputerName tmh-prod-tmh-eus-ehn.servicebus.windows.net -Port 5671
  2. Interpreta los resultados.
    • Port is open (Expected). This means the Robot can successfully communicate with Azure Event Hub.
      TcpTestSucceeded : TrueTcpTestSucceeded : 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) failedWARNING: TCP connect to (x.x.x.x : 5671) failed
      TcpTestSucceeded : FalseTcpTestSucceeded : False

      Allow the following outbound connection (firewall rule).

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