356CHAPTER 8: THE EVENT LOG
If you have disabled Smart Event Analysis on a global basis then the per-event Smart Event Analysis settings are ignored. See “Controlling Smart Event Analysis”on page 352.
Setting Thresholds A monitor-based event is generated when the state of a monitor exceeds for Monitor-Baseda configured threshold and, if event suppression is enabled, continuously
Events 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:
