Monitoring Segments in the Topology Display (SAP Library

Monitoring Segments in the Topology Display

Use

Use this function to obtain an overview of the monitoring segments of an SAP system. A monitoring segment is a storage area in the shared memory of an instance that the monitoring architecture uses for all active contexts and collected monitoring attributes. A monitoring segment contains all active components and data.

The topology display outputs the most important segment data including the current status. As the CCMS agents SAPCCMSR and SAPCM3X are also connected to the central monitoring system using a monitoring segment, the CCMS agents are also displayed here.

For more information about how to start the topology display, see Calling the Display of the Technical Topology.

Features

By default, the system displays the following columns in the Local Segments (<SID>) or Segments (<SID>) tab page:

Column	Meaning
Segment Name	Name of the monitoring segment, with the structure: SAP_CCMS_<Name of SAP instance> or, for CCMS agents, also: SAP_CCMS_<Host_name>
Segment Type	The following segment types are possible: Agent Application server
Destination	RFC destination of the monitored segment
Segment Status	Segment status from the point of view of the local system. The following entries are possible: ONLINE OFFLINE SHUTDOWN COMM.FAIL If an RFC call fails (for example, in the case of the Test connection command), the system displays COMM.FAIL. After a successful RFC call, the system resets the communication status to ONLINE.

You can also show the following columns by choosing the Change Layout button for the ALV Grid Control.

Column	Meaning
Changed by	Unlike the tab page Monitored remote SAP systems, an automatic user (usually SAPMSSY8) can also be entered here as the changer, as the application server automatically registers with the monitoring architecture when starting up.
Status Change (UTC)	Time of the last change of the communication status
Counter for Stat. Chg	Number of changes of the communication status
Segment Server	SAP instance in whose shared memory the monitoring segment exists
Segment Host	Host in whose shared memory the monitoring segment exists
Responsible Server	This column is only filled for CCMS agents. As the CCMS agents originally acted purely as RFC servers, a Responsible Server, that the agent controls, must exist.
System Comm.Prio Comm.typ Comm.Status Change date Change time Version	These columns have identical meanings as those with the same names when Displaying Monitored Systems in the Topology Display.

Activities

In addition to the display functions, the following commands are available to you as pushbuttons in the ALV Grid Control; these commands are only available for local segments.

Command	Explanation
Test Connection	The command performs an RFC call to the selected segment and displays the result.
Delete an entry	With this command, you can delete the entry for the selected segment. This is useful, for example, to correct inconsistencies, or if an application server was permanently removed. The deletion has no consequences for the functioning of the monitoring architecture - the system automatically renews entries for active monitoring segments. This command is only available in change mode, which you start by choosing the Display « Change pushbutton ().
Reset Segment to "WARMUP" Status	In change mode, you can use this command to restart the selected segment (see Reset Segment to WARMUP Status).
Change Segment Status (Only in change mode)	If you no longer wish to monitor a server, choose OFFLINE. It remains in this status until you set it to ONLINE again. Do not set COMM.FAIL or SHUTDOWN manually.
