Defining a Monitoring Request
Setting Event Value Options
Setting Event Value Options
If you select the When value is... from the list in the Notify area, the
Options area displays three choices. Select one or more of these three
options:
Initial Use this option to establish a baseline when monitoring
resources such as available filesystem space or system
load. It can also be used to test whether newly
requested events are being sent.
Repeat Use this option for urgent alerts. The Repeat option
sends an alert at each polling interval as long as the
notify condition is met. Use this option with caution;
there is a risk of high CPU use or filling log files and
alert windows.
Return Use this option to track when emergency situations
return to normal.
To set the frequency of the trigger:
• Click one or more buttons on the list in the Options area (Initial,
Repeat, and Return).
Asynchronous monitors are event-driven, not polled. They generate
messages as events occur. Therefore if the resource is an
asynchronous monitor, the values in the Options area defaults to
Repeat and cannot be changed.
This Options area does not display if you have selected When value
changes or At each interval from the list in the Notify area. In
these cases the options default to Initial and cannot be changed.
