Chapter 54 Configuring the Embedded Event Manager About EEM Send documentation comments to [email protected] Note Your override policy should always include an event statement. An override policy without an event statement overrides all possible events in the system policy. Event Statements An event is any device activity for which some action, such as a workaround or a notification, should be taken. In many cases, these events are related to faults in the device such as when an interface or a fan malfunctions. EEM defines event filters so only critical events or multiple occurrences of an event within a specified time period trigger an associated action. Figure 54-2 shows events that are handled by EEM.
