CCMS Agents (SAP Library

CCMS Agents

Purpose

The Monitoring architecture provides an infrastructure to monitor your IT environment and its components. Monitoring data is stored in the shared memory of every server with a running SAP instance or a running agent.

Read and write access from the central monitoring system is possible in two different ways:

Using a defined ABAP interface, in the case of an SAP instance
Using the agent, in the case of a server of your choice, on which the agent is installed and active

Agents allow you to:

Include SAP components that are not available through any ABAP interfaces, such as with the Internet Transaction Server (ITS)

Include components that are not part of the SAP environment

Make an alternative connection route to a shared memory segment available

Optimize reading and writing of data from a performance point-of-view

Connect to a shared memory segment without requiring a free work process

CCMS agents are independent processes with an RFC-capable interface to a central monitoring system and an interface to the shared memory.

Implementation Considerations

You should use one of the three existing CCMS agents, according to the type of system that you want to monitor:

Agent	Task
SAPCCMSR	Monitors components on which there is not an active SAP instance
SAPCCM4X	Monitors SAP systems from SAP Basis Release 4.X
SAPCM3X	Monitors SAP systems with SAP Basis Release 3.X using the CCMS monitoring architecture

Features

The three CCMS agents have the following characteristics:

SAPCCMSR

Monitors components on which there is no active SAP instance (such as log files, stand-alone databases or operating system components). SAPCCMSR is closely connected with the central monitoring system.

SAPCCM4X

Improves the monitoring of SAP systems with SAP R/3 Basis Release 4.X or higher. This agent provides an alternative connection route to the monitoring information in the shared memory of a mySAP.com instance. As this alternative connection route no longer requires a free work process, it is independent of the error statuses of the SAP instance and therefore more robust.

Note

For more information, see SAP Note 322075.

SAPCM3X

Allows the monitoring of SAP instances of SAP R/3 Basis Release 3.X through the CCMS monitoring architecture (SAP R/3 3.X systems do not have their own CCMS monitoring architecture).

Note

For more information, see SAP Note 308061.

All of these CCMS agents can load shared libraries, which deliver additional information to the central monitoring system. An example of this is an extension to monitor the Internet Transaction Server (ITS) and cached disk subsystems, such as EMC Disc Arrays (Symmterix).
