Procedure documentation Displaying Technical Data for the Adapter Engine  Locate the document in its SAP Library structure


You can display current technical data for several server nodes for the selected Adapter Engine.


You have started the Runtime Workbench, are in component monitoring, and have selected an Adapter Engine as the component.


To display current technical data for the selected Adapter Engine, proceed as follows:


       1.      On the Status tab page, choose Engine Status. You need to enter the user and password for the selected Adapter Engine.

       2.      Select the required server node.

The system displays node-specific system information. Additional detailed information is displayed on the available tab pages.

       3.      Select the tab page with the required information.

Backlog Tab Page

This tab page shows all communication components for the senders and receivers that are defined for the selected Adapter Engine in the CPA cache.

You can restrict the number of communication components to be displayed with a filter. You can enter an asterisk (*) here for this.

The number of messages currently still in processing (backlog) is displayed for each communication component. The number is not node-specific and represents the sum of messages across all nodes.

You can select a communication component for monitoring by the SAP NetWeaver Administrator. In addition to the selected communication components, this also always displays the total sum of messages for all communication components.


For performance reasons, only select particular communication components for monitoring, not all communication components.

To make the data visible in SAP NetWeaver Administrator, proceed as described in Modifying the State of a Set of Monitors. In the monitoring tree, select the nodes Server Services Adapter Framework Messaging System.

To display the monitored communication components, choose Messaging System Receiver Services or Messaging System Sender Services.

Waiting messages (status WAIT)

      Processing Backlog (without errors):

Messages to be delivered (status TBDL) and messages that have been delivered (status DLNG)

      Error Backlog:

You can connect the monitor to the SAP Computing Center Management System (CCMS). There, you can define corresponding threshold values to generate alerts for individual backlog categories and communication components.
