How Embedded Event Manager Works

Embedded Event Manager, or EEM, is a Cisco software component that provides admins the ability to track and monitor events that occur on your Cisco device. Because many of these actions are predictable, EEM has the capacity to apply actions admins have predetermined. This is a critical advantage for systems and network administrators, where automation is a crucial concept.

Event detectors are used by EEM to recognize when events have occurred and define what has happened. Some of these include SNMP, syslog, counter, CLI events, and timers.

Once an event has been detected and classified, the event manager can take action. EEM consists of two separate and independent pieces: Scripting and Applets. Scripts are actions that have been coded in interpreter language (TCL), while Applets are collections of CLI commands.

Some of the actions EEM can take include sending emails, executing or disabling certain commands, generating SNMP traps, reloading routers, generating prioritized syslog messages, switching to secondary processors in a redundant platform, and requesting further system information after an event is detected.
