What are agents and the controller?
AppDynamics agents are plug-ins or extensions that monitor the performance of your application code, runtime, and behavior. They’re deployed to every corner of your application environment, from devices, to containers and hosts, to applications.
The AppDynamics controller receives metrics from agents and sends them instructions. All of this performance activity is displayed via the Controller UI, which allows you to view data insights from multiple applications in one place.
How agents deliver precision insights
Once deployed, Agents immediately monitor every line of code. Unique tags are assigned to every method call and every request header. This allows AppDynamics to trace every transaction from start to finish — even in modern, distributed applications.
Supported platforms: AWS, Microsoft Azure, Google Cloud and multi-cloud.
How the controller helps resolve issues, fast
The Controller is updated in real-time, even in hyper-complex applications with thousands of Agents, helping you monitor, troubleshoot and analyze your entire application landscape — from backend infrastructure to the end user — in one simple interface.
