This agent improves the monitoring of ABAP instances with SAP Basis 4.X or higher. The central monitoring system must have a release status of at least SAP Basis 4.6C. This agent provides an alternative connection route to the monitoring information in the shared memory of an ABAP instance. As this alternative connection method does not require a free work process, the access method is independent of error states of the SAP instance and is therefore more robust.
Systems as of SAP Basis 4.0 have their own CCMS monitoring architecture runtime environment. This means that they have their own monitoring segment in the shared memory area of the running system. After its installation, the SAPCCM4X agent attempts to attach itself to and to work with this monitoring segment in shared memory when it is started.
If this segment does not exist (that is, if the monitored system is not running), the agent does not create it, to avoid interfering with the shared memory management in the restarting system. In this case, the SAPCCM4X agent works with the monitoring segment that it creates in its process memory and the contents of which it synchronizes with the monitored system. SAPCCM4X constantly checks whether the monitored system is active again, and when it is, works with the monitoring segment in the shared memory again, after synchronization.
The central monitoring system automatically first attempts to read data from the monitored
system through the RFC destination of the CCMS agent. If the agent is not active, the system
reads the monitoring data from the monitored SAP instance using the standard RFC, as previously (for more information, see SAP Note 322075).
Note that even if you are using the SAPCCM4X agent, you still continue to need the standard RFC connection anyway.
