CCMS agents are no longer required for purely SAP NetWeaver 7.1 landscapes; their functions are performed by SAP NetWeaver Management Agents. More information about when you still require CCMS agents for SAP NetWeaver 7.1: CCMS Agents: Central Monitoring for Components up to SAP NetWeaver 7.0.
Distributed Statistics Records (DSRs) are an extension of the concept of the ABAP statistics data. DSRs provide you with information for a DSR component about the workload generated and the resources used in the system by actions.
The DSRs are written to a separate directory in the file system of the DSR component. A specified number of files are written in each component subdirectory. A new statistics file is started hourly. As soon as the maximum number of files has been reached, the system overwrites the oldest statistics file.
Depending on the DSR component and release, this directory has the following path:
UNIX: /usr/sap/ccms/<SysID>_<Inst. No.>/dsr
Microsoft Windows: [drive]:\usr\sap\ccms\<SysID>_<Inst. No.>\dsr
UNIX: /usr/sap/tmp/dsr
Microsoft Windows: [drive]:\usr\sap\prfclog\dsr
This means that the DSR directory is instance-specific as of SAP NetWeaver 7.0 for the DSR components J2EE Engine and TREX, while it is host-specific for all other DSR components.
It is now the task of the CCMS agent to transfer these DSRs to the primary central monitoring system CEN. You can display the data there in the Global Workload Monitor (aggregated data) and in the functional trace (unaggregated data).
