Add New Systems to the List of Systems that Can Be Monitored

On the Configure Availability and Performance Overview screen, choose Load System List (This graphic is explained in the accompanying text). If the desired system does not appear on the list, add the system to it manually (see Add Systems to the Availability Monitoring Manually).

Note

Activating and Deactivating System Availability Monitoring

Select the desired system in the Configure Availability and Performance Overview screen; you can find it either in the list of monitored systems or the list of systems that are not monitored. In the Monitoring group box, choose one of the radio buttons to activate or deactivate monitoring for the system. To deactivate monitoring for a system, the Monitoring of Application Servers must be deactivated.

Activating and Deactivating Server Availability Monitoring

On the following screen, you can either define a single period or a time period that is repeated weekly (such as Friday from 23:00 until Monday 06:00). During this time, the availability of the system specified in the field Name of the system is not monitored for its availability.

Change the Timeout of the Availability Agent CCMSPING

  2. Select the method CCMS_System_Availability and choose Edit Data (This graphic is explained in the accompanying text).
  3. The system displays the Monitoring: Methods screen. Choose change mode with the Display « Change (This graphic is explained in the accompanying text) pushbutton, and choose the Parameters tab page.
  4. Enter the desired wait time in milliseconds for the TIMEOUT parameter, and save your entries.

Result

You have customized the availability monitoring to your requirements. Use the Availability and Performance Overview Monitor from the SAP CCMS Monitor Templates monitor set to perform availability monitoring.

Background

The monitoring architecture uses three tables: CCSMNSDIC, CSMSYS, and CSMSYSAS for availability monitoring. CSMNSDIC contains information about all systems that can be monitored for availability, while CSMSYS contains only the names of the systems that are actually monitored for availability.

Example; CSMNSDIC:

This graphic is explained in the accompanying text

CSMSYS

SYSGUID

SYSID

BNT

BNT

In this example, the availability of system BNT is being monitored.

Using the table CSMSYSAS, the system determines which application servers (field SYSINSTNAM) of which systems (SYSGUID) are to be monitored. The entry C in the INST_CHECK field shows that a corresponding server is monitored for availability.
