解決策: アプリケーション ログを使用して、HTTP エラーの詳細にドリルダウンし、インフラストラクチャの使用状況のグラフを分析して根本原因を切り分けます。

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
• 暗号化
  • 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.
• 認証
  • 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).
• アーキテクチャの概要
  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. 結果を解釈します。
   • 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.
