Open firewall ports between CA Cross-Enterprise APM and the Enterprise Manager to allow them to communicate. To allow the bi-direction communication between all appropriate Enterprise Managers and the Cross-Enterprise APM Agent, update the firewall in both directions.
In a clustered environment, an Enterprise Manager serves as a Manager of Managers (MOM), managing the other Enterprise Managers in the cluster (named Collectors). For load-balancing, the Introscope agents that connect to the MOM are redirected to a Collector with the lightest weight-adjusted load in the cluster. If an agent is disconnected later from the Collector, the agent reconnects to the MOM and can be assigned to a different Collector. In this MOM environment, configure the Cross-Enterprise APM Agent to connect directly to MOM or directly specify an Enterprise Manager.
Follow these steps:
Note: If the Cross-Enterprise APM Agent connects to a MOM with load balancing, then the connection port to this MOM and all defined collectors must be opened. The Enterprise Manager connection port for the collector is defined in the <agent-collector> element of the loadbalancing.xml file on the MOM Enterprise Manager host. For more information about configuring load balancing, see the CA APM Configuration and Administration Guide. For more information about how to download this document, see the recommended reading.
To apply a change, start or restart the Cross-Enterprise APM Agent.
