Question

A new Java process instrumented with the AppDynamics agent started with no errors in the log file. There is verified network connectivity between the host running Java and the Controller on all ports and load applied to the process. However, the host does not appear in the Tiers and Nodes view, and there are no metrics in the Metric Browser. What else should you check?

Explanation

One possible reason why the host does not appear in the Tiers and Nodes view and there are no metrics in the Metric Browser is that the license count for that agent type has been exceeded. You can check the license usage and availability by going to Settings > License in the Controller UI. If the license count is exceeded, you can either purchase more licenses or deactivate some agents to free up the license slots.
