8.1 Overview of the monitoring suspension function
You can use Performance Management to suspend or resume monitoring of operations such as alarms and health checks for monitoring targets for which maintenance work is performed while the monitoring targets are running. The functions to suspend and resume monitoring are collectively called the monitoring suspension function.
When a monitored host or service is stopped by maintenance work during operation, an alarm event or health check event that indicates an abnormal or warning situation occurs in normal monitoring. At this time, you can suspend monitoring for the monitoring target to be stopped in advance to prevent the stopping of the host or service from being reported as an abnormal situation. Additionally, you can select whether or not to store operating information from when monitoring is suspended, allowing you to analyze the operation status by using data that excludes the corresponding duration of suspension.
Suspending and resuming monitoring can be set in the Monitoring Suspension Settings window in the Agents tree or by using a command. You can select targets by host or agent and specify the monitoring suspension settings for them by using one operation.
Major functions related to the monitoring suspension function are described below:
-
Alarm
Alarms bound to an agent for which monitoring is to be suspended are suspended.
-
Health check
Health checks for a host and agent for which monitoring is to be suspended are suspended.
-
Storage of operating information
Storage of operating information is suspended. Note that you can set storage of operating information to be continued when you specify the monitoring suspension settings.
You can check the monitoring suspension duration in the Event Monitor window or Event History window.
Note that, even if storage of operating information is suspended, real-time reports can be displayed.
