CA APM Command Center provides an overview of CA APM agents in your environment which are managed by the Command Center through an Agent Controller.
The application's web user interface displays all agents enabled for management by the Command Center. You can see the status of the agents and review their diagnostic reports.
CA APM Command Center enables you to:
  • Get a list of Java agents installed in the environment
  • Download agent log files without having to log in to the monitored server
  • Obtain diagnostic information from a Java agent, such as Java agent version, Java virtual machine (JVM) provider, JVM version, JVM start-up parameters, application server name and parameters, agent configuration, and so on
  • Change the log level of an agent
The following diagram shows the architecture of CA APM Command Center. It displays the relationships and the direction of data flow between the components, the protocols used, and the default port numbers.

CA APM Command Center consists of the following components:
Configuration Server
The Configuration Server manages connections to all Agent Controllers and stores attributes that are associated with all discovered agents.
The Configuration Server also stores diagnostic information requested for individual agents and log files requested by the user.
Communication between the Configuration Server and Agent Controllers is ensured by Apache ActiveMQ message broker.
Agent Controller
The Agent Controller acts as a point of presence on a server where an application server and Java Agent are installed. Typically, there is only one Agent Controller on each server, though there can be more than one application server (and therefore Java agent) on the server. One Agent Controller can manage multiple Java agents.
As the Agent Controller and Java Agent are separate entities, the Agent Controller must discover Java agents so that it can manage them. To enable this discovery process, Agent Controller opens a local socket on a specific port where it listens for registrations from Java agents. A Java agent extension periodically attempts to connect to the socket. If the connection is successful, the agent sends information about itself to the Agent Controller.
User Interface
The web user interface displays all agents enabled for management by the Command Center and enables users to review reports for these agents. The user interface uses RESTful APIs to communicate with the Configuration Server.
