You can also register the SAP NetWeaver management agents with an additional monitoring system. This means in principle that data and alerts are no longer sent just to one system, but rather to two systems; the corresponding agent also processes requests from both monitoring systems as a Web service.
Both systems are able to display data or alerts; however, you only have write access to properties or alerts of the nodes in the primary central monitoring system. The system in which you first register a monitored system/host (see Registering SAP NetWeaver Components and Hosts in CEN ) is the primary system. In detail, you cannot execute the following commands in the secondary monitoring system:
The possibility of defining two monitoring systems has the following advantages:
Performing Registration with Two CENs
To register a component monitored by an agent with two CENs, perform the usual registration (as described in Registering SAP NetWeaver Components and Hosts in CEN ) first in the primary and then in the secondary CEN.
The sequence when doing this is critical. If a system adopts a component as a central monitoring system, by default it takes the role of the primary CEN. This is the case unless this component is already centrally monitored by another CEN. In this case, the new system takes on the role of the secondary CEN.
To switch the primary and secondary CENs, log on to the previous secondary CEN, and in the topology display, choose Adopt Agent (see Monitoring Agents in the Topology Display ).
