Configure Network Topology and Firewall Settings

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:

1. Open the Introscope_Cross-Enterprise_APM.profile file at /root/C7C4960/Cross-Enterprise_APM/config:
   • Edit the introscope.agent.enterprisemanager.transport.tcp.host.DEFAULT=hostname property to the server name or IP address of the Enterprise Manager (or MOM).
   • Edit the introscope.agent.enterprisemanager.transport.tcp.port.DEFAULT=5001 property if you want to use an Enterprise Manager connection port other than the 5001 default port.

     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 host. For more information about configuring load balancing, see the CA Application Performance Management Configuration and Administration Guide.

   • If you have multiple TCP/IP stacks with differing security permissions, specify the following properties:

     introscope.agent.enterprisemanager.transport.tcp.local.ipaddress.DEFAULT=
     introscope.agent.enterprisemanager.transport.tcp.local.port.DEFAULT=
     

2. Save the changes.

To apply a change, start or restart the Cross-Enterprise APM Agent.
