Smart Event Analysis
on a global basis then the

Setting Thresholds
for Monitor-Based
Events
A monitor-based event is generated when the state of a monitor exceeds
a configured threshold and, if event suppression is enabled, continuously
exceeds the threshold for a predetermined time or number of polls.
See
“Event Suppression”
on
page 325
for more information on event
suppression and
“Controlling Smart Event Analysis”
on
page 352
for
details on how to enable and disable it.
By changing the threshold for a monitor you can control the generation
of events for that monitor. Lowering the threshold indicates that a
monitor should be particularly sensitive to high values, and so events will
be generated more frequently. Increasing the threshold indicates that
high values are normal for that monitor or that the monitor should be less
sensitive to high values, and so events will be generated less frequently.
High and Warning Thresholds
Multi-state monitors have two thresholds: a high threshold and a
warning threshold. If a monitor exceeds its high threshold for long
enough then a high severity event will be generated. Similarly, if a
monitor exceeds its warning threshold for long enough, but does not
trigger a high severity event, then a warning severity event will be
generated.
3Com Network Director allows you to configure the high threshold for
multi-state monitors and then automatically determines a suitable setting
for the warning threshold, based upon the configured high threshold and
the type of monitor. The warning threshold cannot be manually
configured. See
“Threshold Settings Dialog Box”
on
page 357
.
As bi-state monitors only have a good and a bad state, they do not have
a warning threshold, only a high threshold. The high threshold is fixed for
bi-state monitors: if a bi-state monitor enters its bad state then it has
crossed the high threshold.
Launching the Threshold Settings Dialog Box
The
Threshold Settings
dialog box can be launched for a monitor in the
following ways:
