Changing the Monitoring Frequency and Timeouts of CCMSPINGLocate this document in the navigation structure

Use

In addition to configuring which systems and application servers are to be monitored by CCMSPING (seeConfiguring Availability Monitoring), you can also define the frequency with which CCMSPING should perform the availability monitoring, and for how long it should wait for a response from the message servers and the application servers when it does so.

Activities

Changing Timeouts and Monitoring Frequency of CCMSPING (with -push option)

The technical settings of the registered availability agent CCMSPING are stored in the table ALAVLCTRL. This table is only relevant for those agents that actively report the availability values to the central monitoring system (CEN), that is, agents that were registered with the -push option (seeInstalling the CCMSPING Availability Agent).

Since there is no separate user interface for maintaining the technical settings, you need to make the settings in the Data Browser (transaction SE16):

  1. Start transaction SE16 in CEN. The Data Browser: Initial Screen appears.
  2. In the Table Namefield, enter ALAVLCTRL and choose (Table Contents).
  3. On the Data Browser: Table ALAVLCTRL: Selection Screen, choose the (Execute) button.
  4. There is a separate row for each agent that is registered with CEN. The RFC destination of the agent is displayed as its name in the PING_DEST column. The destination has the naming convention CCMSPING.<Host>.<InstNo (Default=00)>. To change an entry, select the desired agent, and choose (Change). You have the following options here:
    • Changing the Timeout for Message Servers

      To change the length of time for which a specific CCMSPING waits for a response from the ABAP and Java message servers, enter the desired wait time in milliseconds for the relevant CCMSPING as the value of the entry PING_TIMEOUT. The default value is 1500 (1.5 seconds).

    • Changing the Frequency of the Availability Monitoring

      By default, the CCMSPING agent calls the message server once a minute for availability monitoring. It is not possible to have the monitoring performed more frequently. To have the monitoring performed less frequently, enter the desired interval in seconds for the relevant CCMSPING agent as the value of the entry PING_FREQ.

      Note

      Two additional entries: TRACE and TIMESTAMP are useful for finding and correcting errors. For more information, seeFinding and Correcting Errors with CCMSPING

  5. During the logon check, the CCMSPING calls the application server directly. To change the timeout for these calls, proceed as follows:
    • ...
    1. Start transaction RZ21 in CEN.
    2. In the Methods group box, select Method Definitions and choose Display Overview.
    3. Select the method CCMS_AVAIL_LOGON_CHECK, and choose Edit Data ().
    4. The system displays the Monitoring: Methods screen. Choose change mode with the Display «Change () pushbutton, and choose the Parameters  tab page.
    5. To change the time that CCMSPING waits for the response of an application server in the case of an RFC call, enter the desired wait time in milliseconds for the RFCPING_TIMEOUT parameter. The default value is 10000 (10 seconds).
    6. Save your entries.

Changing the Timeout of the Availability Agent CCMSPING (Without the -push Option)

If you have registered CCMSPING without the -push option, the availability monitoring is essentially performed every five minutes. You can also register only one CCMSPING with your CEN. You can, however, change the above timeouts. To do this, follow the procedure below:

  1. Start transaction RZ21 in CEN.
  2. In the Methods group box, select Method Definitions and choose Display Overview.
  3. Select the method CCMS_System_Availability and choose Edit Data ().
  4. The system displays the Monitoring: Methods screen. Choose change mode with the Display «Change () pushbutton, and choose the Parameters  tab page.
  5. To change the time that CCMSPING waits for the response of the message server, enter the desired wait time in milliseconds for the TIMEOUT parameter. The default value is 1500 (1.5 seconds).
  6. To change the time that CCMSPING waits for the response of an application server in the case of an RFC call, enter the desired wait time in milliseconds for the RFCPING_TIMEOUT parameter. The default value is 10000 (10 seconds).
  7. Save your entries.
