Defining a Monitoring Request
Specifying when to send Event Notifications
Chapter 2 29
Specifying when to send Event Notifications
When you create a request, you specify the conditions under which you
want to collect resource status values. While the monitor may be polling
disks every five minutes, for example, you may only want to be alerted
when something happens that requires your attention. Specify these
conditions in the Notify area of the Monitoring Request Parameters
screen. Here are the terms under which you can be notified:
Table 2-1 Options to specify when Event Notifications have to be sent
When value is ... You define the conditions under which you
wish to be notified for a particular resource.
Choose an operator (=, not equal, >, >=, <, <=)
and one of the possible values returned by the
monitor. The content of the value field varies
depending upon the resource monitored. The
value field might display as a list box or a
blank field.
If a list box displays, use the scroll bar and
select from the list. If a numeric field displays,
type in a value.
When value changes This sends notification every time a resource
value changes. Typically this is used for
resources whose values change infrequently.
Change here means any change. For example,
you could receive notification every time the
number of mirrored copies of data changes,
whether it is from 2 to 1 or from 1 to 2.
At each interval This sends notification at each polling
interval. It is commonly used for reminders or
for gathering data for system analysis. Use
this for only a small number of resources at a
time, and with long polling intervals of several
minutes or hours; there is a risk of affecting
system performance.
