The SAP NetWeaver management agent sapstartsrv (more information: Administration/Monitoring of SAP Components with sapstartsrv) contains the functionality for different central monitoring functions. The functions of the CCMS agents are integrated into sapstartsrv as a static library for this purpose; the CCMS agents therefore no longer exist as standalone executables as of SAP NetWeaver 7.0 EhP2.
The monitoring functions are started in a separate thread within sapstartsrv. This thread connects to the monitoring segment in the shared memory of the monitored instance. Applications can access the monitoring functions of sapstartsrv through a Web service interface. This interface replaces the RFC server part of the CCMS agent.
An application (usually an ABAP or dual-stack system) can register as a central monitoring system (CEN). The registration is performed using a protected Web service. During the registration, the caller sends sapstartsrv information about the CEN and the logon data for the CSMREG user.
Types of Agents
Depending on the type of monitored component, there are different types of SAP NetWeaver management agents or CCMS agents:
Monitored Component | Agent |
---|---|
(as of SAP NetWeaver 7.0 EhP2 in each case) |
Instance agent; an instance agent runs for each monitored instance |
|
Host agent; one host agent runs for each monitored hosts (including hosts on which one or more instance agent is running) |
|
CCMS agent SAPCCM4X |
|
CCMS agent SAPCCMSR -j2ee |
For more information about when you still need to use CCMS agents, see CCMS Agents: Central Monitoring for Components up to SAP NetWeaver 7.0..
Communication
An SAP NetWeaver management agent communicates with CEN in the following way:
You do not need to install the host and instance agents separately with SAP NetWeaver components of the current release, since these are already installed as part of the installation of the component.
You only need to download and install the host agent yourself for hosts with no SAP NetWeaver components (see SAP Host Agent Installation).
The monitored component must be registered with CEN (see Registering SAP NetWeaver Components and Hosts in CEN).
