Verify Agent Controller Communication

Use the Splunk AppDynamics UI to verify that the agent can connect to the Controller.

  1. In a browser open:
    http://<controller-host>:<controller-port>/controller
    If you cannot connect to the Controller in Internet Explorer,see Check Internet Explorer proxy settings
  2. Log in to the Controller UI.
  3. Select the application to open the Application Dashboard.
  4. In the left navigation panel, select Servers > Tiers & Nodes and open the Health tab.
The Health tab lists the tiers, their nodes, and App Agent Status. When an agent successfully reports to the Controller, an up arrow symbol displays.

See Agent-to-Controller Connections.

  • When deploying multiple agents for the same tier, determine if the correct number of nodes reports into the same tier.
  • After sending a request to your web application, data should display on the Controller UI. The agents should display in the Application Flow Map of the Application Dashboard.

If no data displays after a few minutes:

  • Verify that the Agent is writing its log files.Windows Server 2008 and later: %ProgramData%\AppDynamics\DotNetAgent\Logs\AgentLog.txt
  • If the log file exists, open it and review for errors.
  • If the log file does not exist, run the Windows Event Viewer and review the application messages.
  • If there are no Splunk AppDynamics event messages, look for messages from the .NET Runtime.
