A falling CPU utilization threshold specifies the percentage of CPU resources that, when CPU usage falls below this level for a configured period of time, triggers a CPU threshold notification. The event manager applet (which matches the syslog messages) then ignores the rising threshold syslog message.

What is EEM? EEM (Embedded Event manager) is a software component of Cisco IOS, XR, and NX-OS. EEM gives you high abilities to admin your Cisco device by tracking and monitoring events that take place on your Cisco device and then apply action you already decided early, EEM by giving you this ability, it allows you to automate many tasks. EEM consists of event detectors, an event manager server, and action routines called policies. Two policy engines are defined: the Cisco IOS Software CLI applet interface and the EEM Script (which uses the the TCL subsystem and interpreter).
Writing Your First EEM Applet Posted by Jimmy Ray Purser in Network Sheriff on Jun 19, 2009 3:09:44 PM It’s hard to find a Cisco IOS feature cooler then Embedded Event Manager. The "show process cpu sort" shows normal output. However, the "show process cpu history" indicates CPU utilization was always 60% and spike over 90% from time to time. To capture which process is the culprit, Cisco recommended to use following EEM (Embedded Event Manager) applet:

Introduction: The EEM(Embedded Event manager is a software component of cisco IOS, XR, and NX-OS makes life easier for administrators by tracking and classifying events that take place on a router and providing notification options for those events. releases of the Catalyst 6500 Cisco IOS Software. Each event detector is a separate subsystem in itself and is responsible for interfacing between the publisher of an event and the Event Manager Server. Each of the supported event detectors in this initial Cisco IOS Software release is detailed in the following list.
To display the values of event manager parameters, use the show event manager environment all command. Configuration Examples for the Online Insertion Removal Event The online insertion removal (OIR) event does not have a default policy. The Cisco Embedded Event Manager is a powerful tool which can pretty much do anything you want it do. I will go through a few simple embedded event manager examples and step through the configuration line by line. Embedded Event Manager Example #1. This EEM example will monitor if an interface goes down and will generate a custom syslog message.

The following EEM script will poll a SNMP OID and look for a value of 80% or above CPU usage. If the CPU hits 80% usage, it will then capture data from the commands and write that to a file called high_cpu on disk0.

Configuring Description of an Embedded Event Manager Applet; Registering and Defining an Embedded Event Manager Applet. Perform this task to register an applet with Embedded Event Manager and to define the EEM applet using the Cisco IOS CLI event and action commands. Only one event command is allowed in an EEM applet. I am just discovering EEM scripts. They are pretty cool! Here are couple of simple scripts for high CPU/Mem. Probably need to tweak the sh commands for the high CPU, I used only the high memory script. Additionally, you could do this within Cisco IOS itself using Event Manager Applets. I have not tested this at all, it is pulled straight from a presentation I attended at Cisco Live. I would recommend testing it thoroughly before deploying. event manager applet cpu_stats
Embedded Event Manager. Embedded Event Manager (EEM) is a powerful device- and system-management technology integrated in NX-OS. EEM helps customers harness the network intelligence intrinsic to Cisco’s software and give them the capability to customize behavior based on the network events as they happen.

I have configured EEM applet to run when the CPU usage is greater than 50% and an e-mail containing the result of the "show cpu processes" command was sent to an engineer, I'm sure that I filled with valid mail information but I did not receive anything. In this document I will include 4 ways to detect high CPU spikes on Cisco routers and switches and do something about it using EEM (Embedded Event Manager). Later in the document I will add some command that can helpfull in troubelshooting high CPU. This document is just a draft version.I will try to add more and edit weekly bassis to improve quality. Event none is used if you want to manually run the eem applet, like you tried to do. In your case (i guess you need to test your applet), you can create a 2nd applet that uses event none and just sets the
