Using the Event Monitoring Service (November 1999)

38 Chapter3
Defining a Monitoring Request
Specifying When to Send Event Notifications
To set an event trigger:
• Select from the listed options in the Notify area (When value is...,
When value changes, or At each interval).
Asynchronous monitors are event-driven, rather than polled. They
generate messages as events occur. Therefore, if the request is for an
asynchronous monitor, only the When value is... option is
available.
NOTE Updated monitors may have new status values that change the meaning
of your monitoring requests, or generate new alerts. For example,
assume you have a request for notification if status > 3 for a resource
with a values range of 1 through 7. You receive alerts each time the value
equals 4, 5, 6,or 7. If the updated version of the monitor has a new status
value of 1 through 8, you also see alerts when the resource equals 8.
