 Defining Monitors with the DEFINE_R3_SYSTEMS/GET_MTE_BY_CLASS RulesLocate this document in the navigation structure

You can use these two rules to quickly and simply create monitors if you first answer these two questions:

  • From which systems is monitoring data to be displayed?
  • What MTE classes does the monitoring data to be displayed have?

    You can determine the MTE class of the desired data by calling a monitor that contains the desired nodes, switching to the Technical View: Info on MTE, or by selecting the desired node and choosing Properties.

Monitor Definition

To create a monitor, proceed as described in Creating and Changing Monitors. The figure below shows a simple rule-based monitor definition using the above rule (for information about the possible rules and display options, see Rule MTEs: Rule Descriptions and Use):

Note the following for the CCMS_DEFINE_R3_SYSTEMS rule:

  • You usually use the rule as the root node of the monitor.
  • You define the systems to be displayed in the parameter R3System. You can enter the following values when doing so:
    Entry Meaning


    Local system


    All systems that are known to the monitoring architecture as monitored systems (see Registering SAP NetWeaver Components and Hosts in CEN)

    <any name>

    System group; you can define a system group yourself that contains the desired systems (see Maintaining System Groups)

  • In the display options for the rule, you should activate the indicator Display virtual summary nodes in the monitor if, and only if, you want to display multiple systems. If you are only monitoring one system, another level with the system name does not provide any new information, but rather makes the monitor less clear.

Note the following for the rule CCMS_GET_MTE_BY_CLASS:

  • If (as in this example) there is a CCMS_DEFINE_R3_SYSTEMS rule above this rule, the rule inherits the system, otherwise, you usually define the systems yourself.
  • It is usually not necessary to select Display long MTE name in the display options. You should instead select only the parts of the MTE name that are necessary to understand the monitor display. In this example, this is the context (which specifies the instance for most nodes).
Monitor Display

If you choose Generate Monitor  () for the above monitor definition, the following monitor is generated:
