Understanding Embedded Event Manager

The embedded event manager (EEM) monitors key system events and then acts on them though a set

policy. This policy is a programmed script that you can use to customize a script to invoke an action

based on a given set of events occurring. The script generates actions such as generating custom syslog

or Simple Network Management Protocol (SNMP) traps, invoking CLI commands, forcing a failover,

and so forth. The event management capabilities of EEM are useful because not all event management

can be managed from the switch and because some problems compromise communication between the

switch and the external network management device. Network availability is improved.if automatic

recovery actions are performed without rebooting the switch,

and the event subscribers (policies). The event publishers screen events and when there is a match on an

event specification that is provided by the event subscriber. Event detectors notify the EEM server when

an event occurs. The EEM policies then implement recovery based on the current state of the system and

the actions specified in the policy for the given event.
