Service group |
This column displays the name of the service group for each monitored service. |
3 |
Service |
This column displays the name of each monitored service. |
4 |

Clicking this button starts monitoring of the monitored services whose check box is selected. |
6 |
Stop button |
Clicking this button stops monitoring of the monitored services whose check box is selected. |
(3) Supplemental notes
Until start monitoring processing has finished for the selected monitored services, no other operations can be performed.
If no check boxes are selected in the Start/Stop monitor area, you cannot click the Start button.
If you click the Start button while a monitored service that is already being monitored is selected, its monitoring status does not change.
When you select multiple monitored services and start monitoring, their start processes are executed in parallel. As a result, even if an error occurs in the start process for one monitored service, the start processes continue for the other monitored services. However, if you attempt to start monitoring of a monitored service that has been deleted by another user, an error message will be displayed and the start processes for all the monitored services will be suspended. In such a case, you must start over by selecting the monitored services whose monitoring is to be started and clicking the Start button again.
If monitoring fails to start for any of the selected monitored services, an error message is displayed. Correct the error, and then click the Start button again.
If the SLM - UR that is to monitor the selected monitored services is not running, monitoring of those monitored services will not start. You can check which monitored services failed to start in the KNAS16304-E message that is output to the message log.
When monitoring of a monitored service starts, the start time is output to the message log. The messages that are output for the various types of monitoring are listed below.
Service performance monitoring
Threshold monitoring: KNAS32017-I message.
Trend monitoring: KNAS32018-I message.
Error detection: KNAS32019-I message.
System performance monitoring
Threshold monitoring: message KNAS32023-I.
Trend monitoring: KNAS32024-I message.
Error detection: KNAS32025-I message.
Availability monitoring
Availability monitoring: KNAS32027-I message.
When you start monitoring a monitored service, monitoring by the SLM - UR that is being used to monitor stops and then restarts. This means that, for Web transactions that are monitored by the same SLM - UR as the monitored services that are starting, their monitoring will start fresh again from the first Web access following restart.
Until stop monitoring processing has finished for the selected monitored services, no other operations can be performed.
If no check boxes are selected in the Start/Stop monitor area, you cannot click the Stop button.
If you select a monitored service whose monitoring has already stopped and click the Stop button, its monitored status will not change.
When you select multiple monitored services and stop monitoring, their stop processes are executed in parallel. As a result, even if an error occurs in the stop process for one monitored service, the stop processes continue for the other monitored services. However, if you attempt to stop monitoring of a monitored service that has been deleted by another user, an error message will be displayed and the stop processes for all the monitored services will be suspended. In such a case, you must start over by selecting the monitored services whose monitoring is to be stopped and clicking the Stop button again.
If monitoring fails to stop for some of the monitored services, an error message is displayed. Correct the error, and then click the Stop button again.
Even if the SLM - UR that is monitoring the selected monitored services is not running, monitoring of the selected monitored services will stop successfully. The KNAS16414-W message indicating that SLM - UR is not running will be output to the message log.
When you stop monitoring a monitored service, monitoring by the SLM - UR that is being used to monitor stops and then restarts. This means that, for Web transactions that are monitored by the same SLM - UR as the monitored services that are starting, their monitoring will start fresh again from the first Web access following restart.
If you start (resume) monitoring more than 24 hours after stopping monitoring, there might not be a full minute's worth of acquired information since the time monitoring finally stopped to use for the baseline calculation. In this case, you can correct this situation by continuing to monitor for at least one hour, or by stopping monitoring and restarting.
