Registering with Multiple Central Monitoring Systems

You can register the CCMS agents with multiple monitoring systems. This means in principle that data and alerts are no longer sent just to one system, but rather to multiple systems; the corresponding agent also processes requests from all monitoring systems as an RFC server.

Both systems are able to display data or alerts; however, you only have write access to properties or alerts of the nodes in the primary central monitoring system. The primary system is the system that is specified first during registration (see Installing and Registering CCMS Agents). In detail, you cannot execute the following commands in the secondary monitoring system:

• Change properties of nodes that are supplied with values using a CCMS agent, such as threshold values; to display the threshold values, use the corresponding technical view of the alert monitor
• Complete or reset alerts
• Have central auto-reactions executed (see Setting Up Central Auto-Reactions). In the case of central auto-reactions, alerts in the monitored systems create an alert in the assigned central monitoring system. As an alert should always trigger exactly one action for consistency reasons, central auto-reactions are only performed in the primary central monitoring system.

The possibility of defining multiple monitoring systems has the following advantages:

• Operating system data for dedicated database servers should be transferred using the CCMS agent SAP CCMSR to be able to display the data in the associated system using transactions ST06/OS07 and in the monitoring architecture. If this system is, in turn, part of a system landscape with a central monitoring system, you should make the following settings when registering the agent:
  • Choose the central monitoring system of the system landscape as the primary monitoring system.
  • Choose the system with which the database server is associated as an additional monitoring system
• In high availability solutions, you can define an additional monitoring system as a replacement for emergencies or maintenance periods, without having to restart or reregister the CCMS agents for these periods.

Start File CSMCONF with Multiple Central Monitoring Systems

For dialog-free registration with multiple central monitoring systems, extend the CSMCONF start file (see Dialog-Free Registration of the CCMS Agents). The start file initially consists of the following four sections, which define properties and the users used by the central monitoring system:

CEN_CONFIG

CEN_ADMIN_USER

CEN_GATEWAY

CEN_CSMREG_USER(as of SAP Web AS 6.10)

In the case of multiple central monitoring systems, create these four sections as usual for the primary central monitoring system. For every additional monitoring system, create these four sections for the relevant system in the same way, however with the names CEN2, CEN3, ... instead of CEN (the names of the parameters within the sections do not change):

CEN2_CONFIG

CEN2_ADMIN_USER

CEN2_GATEWAY

CEN2_CSMREG_USER (as of SAP Web AS 6.10)

If you use system groups in your central monitoring systems, extend the MGDSYSTEM section. This section contains the system group to which the monitored system is assigned. If you are using multiple central monitoring systems, specify the system group to which the monitored system is assigned for each of these systems:

MGDSYSTEM  SYSTEM_GROUP=<system group in primary CEN>   SYSTEM_GROUP_2=<system group in secondary CEN>   ...
