- Real-Time Event Detection and Response and Task Automation Using Cisco IOS Embedded Event Manager
- Cisco Systems
This document provides an introduction to Cisco IOS Embedded Event Manager (EEM) and describes some potential use cases.
Cisco IOS EEM is a robust tool available to customers and is a significant differentiator for Cisco. Cisco IOS EEM is a value-added feature that is included at no cost (on most Cisco routing and switching platforms) and can reduce customer operating expenses (OpEx) by automating tasks, providing real-time alerts with automated responses, and facilitating troubleshooting. It is essentially a full-time network agent that allows devices to monitor and detect events and immediately take action.
Cisco IOS EEM is embedded in Cisco IOS Software and is enabled by default. There is no requirement or dependency on a centralized management system. Cisco IOS EEM capability is therefore distributed across the network, and Cisco IOS EEM can identify a problem and take action at the point closest to the problem.
This document describes Cisco IOS EEM and provides a technical overview. It also discusses event detectors, policies (using applets and scripts), and use cases.
The appendix provides additional technical details. It discusses multiple event detection, how to gather information using the event_reqinfo command, and decision logic. It also presents script action examples, Tool Command Language (TCL) code snippets, and helpful commands and URLs and steps through execution of a sample script.

This is an excellent, detailed paper that's chock full of great information - exactly what the Webtorials community loves. It's very nicely laid out with an intro to the Embedded Events Manager (EEM), and then has a load of examples and sample cases where the EEM could be used.
As noted in the paper, "Cisco IOS EEM allows customers to:
