Thresholds and event notification
43
NOTE
If you set the threshold for a particular critical event to 100 percent, by the time you are notified, it
may be too late to prevent a failure. However, when you set the threshold to 85 percent, for example,
you may be able to prevent the failure from occurring.
Example
The values at 1 second, 3 seconds, and 5 seconds generate events because they exceed
boundaries. The value at 2 seconds does not generate an event because, although it crosses the
boundary, it remains in the buffer zone. The value at 6 seconds generates an event because it
crosses the lower boundary and returns to a value beyond the buffer zone. The example is shown
as a graph in
Figure 735 on page 1641.
