3.2.8 Setting up the monitoring items for system performance (working with Performance Management)

(1) Before you start

• Verify that you have the service group administrator permissions.

• Verify that the monitored service has been registered.

  For details about how to register monitored services, see 3.2.1 Registering monitored services.

• Verify that monitoring of the monitored service for which monitoring items are to be set up has stopped.

  For details about how to stop monitoring, 4.2.2 Stopping monitoring.

• Verify that configuration information for the monitored service has been specified. For details about specifying configuration information for monitored services, see 3.2.5 Setting up the monitoring items for system performance as configuration information (working with Performance Management).

(2) Procedure

The following shows the Settings window used in this procedure:

To set up monitoring items for system performance:

1. Click the Settings button.

2. In the Setting menu area, select Monitor settings.

   The Monitor settings area is displayed.

3. From the Services area, select a monitored service.

   When you select a monitored service, the service group name, service name, and monitoring items subject to setup are displayed in the Monitor settings area. The current values are displayed under SLO monitor settings and Error Predict. settings. Immediately after a monitored service has been registered, the default values are set.

4. If you will be running threshold value monitoring or trend monitoring, select the Monitor check boxes for the items that you want to monitor under SLO monitor settings, and then enter values in Threshold.

   If (upper-limit threshold value) is displayed, specify an upper-limit threshold. If (lower-limit threshold value) is displayed, specify a lower-limit threshold.

   An error message is displayed if a Monitor check box is selected but no value is specified for that item or an invalid value is entered in the text box.

5. Under SLO monitor settings, specify Occurrence frequency.

   Specify a most recent measurement count for the denominator, and specify an excess count for the numerator. An error will be displayed when the specified excess count is exceeded.

6. If you will be running trend monitoring, select the Trend monitor check boxes for the items that you want to monitor under SLO monitor settings, and then enter the reference time for trend calculation.

   The Trend monitor check boxes are enabled only when the Monitor check boxes are selected. In a Trend monitor text box, enter the time to be subject to trend monitoring.

   An error message is displayed if a check box is selected but no value is specified for that item or an invalid value is entered in the text box.

7. Under Error Predict. settings, enter appropriate values in Days in baseline calculation and Days till start.

   An error message is displayed if an invalid value or nothing is entered in the text box. If you will not be performing an out-of-range value detection, clear the Monitor check box for Error Predict. settings.

8. If you will be performing out-of-range value detection, select the Monitor check boxes for the items that you want to monitor under Error Predict. settings, and then select their Sensitivity settings.

   Select an item that you want to monitor, and then select High, Middle, or Low as its sensitivity. As the sensitivity becomes higher, it becomes easier to detect the item. As the sensitivity becomes lower, it becomes harder to detect the item. Initially, set the sensitivity to Middle, and then you can adjust it later as needed after checking the number of items detected.

9. Under Error Predict. settings, specify Occurrence frequency.

   Specify a most recent measurement count for the denominator, and an excess count for the numerator. An error will be displayed when the specified excess count is exceeded.

10. Select Base monitor item.

    If the service's monitoring configuration is System, the Base monitor item radio buttons and the Clear base monitor item button are displayed.

    Select the Base monitor item radio button corresponding to the monitoring item to be used as the base for determining the dates used for obtaining the baseline for out-of-range value detection.

    If no monitoring item is selected, the service's throughput will be used as the base.

11. Click the Apply button.

    If the monitoring items have been set up successfully, a dialog box to that effect is displayed.

When you click the OK button in the dialog box, the settings are applied.
