Note:
Monitoring will restart after the time specified to wait for start monitoring has elapsed even when
the monitor resource is suspended and/or resumed by using the monitoring control commands.
The wait time to start monitoring is used when there is a possibility for monitoring to be
terminated right after the start of monitoring due to incorrect application settings, such as the
application resource monitored by application monitor resource, and when they cannot be
recovered by reactivation.
