Instrumenting an application adds the AppDynamics application agent (app agent) into the runtime process of the application. This page gives you an overview of installing agents in the application environment.
For application monitoring agents (Java, .NET, Node.JS, and so on), a license validation cycle runs every five minutes. It causes the agents to connect and validate that available license units are not exceeded. Historical usage data is captured during this cycle and stored as five-minute usage data. Every hour, the five-minute usage data is rolled up in hour usage data, which includes data on license unit usage. The five-minute data is purged after a few hours.
