Monitoring Multiple Systems with an Identical System ID 

Use

If you want to monitor multiple systems, you must first define the required RFC connections to them and specify these on the screen Monitoring: Create a New Entry. You also enter the Target System ID of the system to be monitored. This is usually the system ID of the system. The monitoring architecture uses this target system ID to identify and differentiate between all monitored systems.

It is now possible that you want to monitor multiple systems with an identical system ID. This situation occurs in particular in very large IT landscapes or with outsourcing. In this case, nodes from different systems, but which are known by the same target system ID in the monitoring architecture, can no longer be clearly assigned to the corresponding system.

You should therefore assign target system IDs that are unique system landscape-wide in the case of multiple systems with an identical system ID. When doing this, you must only ensure that the first three characters of the target system ID match the system ID of the corresponding system.

The nodes of the systems can then be assigned to exactly one system within the central monitoring system using the unique target system ID. However, only the first three characters of the target system ID are used during access to the destination of the remote system (such as for data collection or to execute and analysis method). As these three characters are the three-character system ID, it is possible to read and process data in the remote system.

When transporting data back to the central system, the system ID is again supplemented by the target system ID known in the central system. The longer target system ID is always used in the central monitoring system.

Prerequisites

The central monitoring system requires Support Package 16 for SAP Web Application Server 6.20, or Support Package 28 for SAP Web Application Server 6.10.

No changes are required in the monitored systems. The releases of the monitored systems are not further restricted; the solution works for all monitored systems as of SAP R/3 4.0B.

Procedure

       1.      Choose CCMS ® Configuration ® Alert Monitor, or call transaction RZ21.

       2.      Choose Technical Infrastructure ® Configure Central System ® Create an Entry for a Remote System.

       3.      The Monitoring: Registering New Contexts for Monitoring screen appears. Specify the desired target system ID. Ensure that you fulfill the following three conditions when doing so:

¡        The first three characters of the target system ID match the system ID of the remote system.

¡        The target system ID is unique among all monitored systems.

¡        The target system ID has a maximum length of eight characters.

The rest of the procedure is the same as that for registering a system to be monitored , as described in Monitoring Multiple Systems.

Example

·        You want to monitor three systems with the system ID PRD at different RFC destinations DES1, DES2, and DES3. You can assign the following target system IDs:

¡        PRD_DES1: System PRDat destination DES1

¡        PRD_DES2: System PRDat destination DES2

¡        PRD_DES3: System PRD at destination DES3

·        You are already monitoring a system with the system ID PRD at the RFC destination DES4 that also has the target system ID PRD in the monitoring architecture. You now also want to monitor an additional PRD system at the RFC destination DES5. In this case, you do not need to change the target system ID of the first system; specify the following target system ID for the new system:

¡        PRD:      System PRD at destination DES4

¡        PRD_NEU: System PRDat destination DES5
