Infrastructure of the SAP NetWeaver Management Agents 

Purpose

The SAP NetWeaver management agents are used to administer and monitor SAP NetWeaver components. They are automatically installed and started during the installation of any SAP NetWeaver components as of release SAP NetWeaver 7.0 EhP2. There are two types of agents, depending on the associated component:

Component	Type
Host	Host agent; one host agent runs for each monitored hosts (including hosts on which one or more instance agent is running)
AS ABAP AS Java Dual-Stack TREX	Instance agent; an instance agent runs for each monitored instance

The agents provide Web services that can be used by applications, including:

●      SAP Management Console (SAP MC) is a browser-based, platform-independent user interface with which you can start, stop and monitor the status of systems and their instances.

●      The SAP Microsoft Management Console (Windows) provides a common framework for system management. SAP has developed the SAP Systems Manager snap-in which allows you to monitor, start or stop the SAP system centrally from the SAP MMC.

●      In the monitoring infrastructure, once the relevant component is registered with the central monitoring system (CEN), data is transferred to CEN (see Registering SAP NetWeaver Components and Hosts in CEN).

The host agent also controls these two executables:

●      Operating System Collector SAPOSCOL

●      sapacosprep; an executable of the Adaptive Computing Infrastructure

Integration

As of this release, the SAP NetWeaver management agents replace the CCMS agents (more information: CCMS Agents: Central Monitoring for Components up to SAP NetWeaver 7.0).).

Constraints

You now only require the classic CCMS agents in the following two cases:

●      You want to monitor any systems with a central monitoring system (CEN) with a release older than SAP NetWeaver 7.0 EhP 1. More information: SAP Note 1368389.

If you are operating a CEN with this old status, note also that you no longer require a CCMS agent SAPCCMSR –j2ee for a monitored dual-stack system as of SAP NetWeaver 7.0 EhP2.  This is because the ABAP and Java stacks share the same monitoring segment as of SAP NetWeaver 7.0 EhP2. Therefore, for dual-stack systems of this type as of SAP NetWeaver 7.0 EhP2, install only the CCMS agent SAPCCM4X. However, this is mandatory, not optional.

●      You want to monitor a system with a release up to SAP NetWeaver 7.0 EhP1. In this case, irrespective of the release of the CEN, you require the classic CCMS agents for this monitored system.
