AppDynamics Application Intelligence Platform
The following sections explain why there is a default limit on number of business transactions for app agents and the Controller.
After every minute, the Controller aggregates and monitors service levels of each business transaction and accepts data from multiple agents processing the same business transaction. The Controller stores data about those agents which identify the business transaction or the entry points and the data about other nodes (where the business transaction context is maintained).
The Controller I/O processing ability is affected by both the number of business transactions and the number of nodes in the application.
To learn more about what type of hardware can efficiently manage how many nodes and business transactions see Controller System Requirements.
The business transaction default limit for agents is very important because AppDynamics is designed for production environments. AppDynamics agents do not simply collect data and report it to the Controller, they also:
Imposing default limits on the number of business transactions is one way to manage the memory requirements of the agent in any type of application environment.
Before changing the limits, take into account the following factors:
