Chapter 33 Configuring Embedded Event Manager
Configuring Embedded Event Manager
Defined by Cisco for a specific sample policy.
•
Cisco built-in variables (available in EEM applets)
Defined by Cisco and can be read-only or read-write. The read-only variables are set by the system
before an applet starts to execute. The single read-write variable, _exit_status, allows you to set the
exit status for policies triggered from synchronous events.
Cisco-defined environment variables and Cisco system-defined environment variables might apply to
one specific event detector or to all event detectors. Environment variables that are user-defined or
defined by Cisco in a sample policy are set by using the
event manager environment
global
configuration command. You must defined the variables in the EEM policy before you register the
policy.
For information about the environmental variables that EEM supports, see the
Cisco IOS Network
Management Configuration Guide, Release 12.4T.

Registering and Defining an Embedded Event Manager Applet
Beginning in privileged EXEC mode, perform this task to register an applet with EEM and to define the
EEM applet using the
event applet
and
action applet
configuration commands.
Note
Only one event applet command is allowed in an EEM applet. Multiple action applet commands are
permitted. If you do not specify the
no event
and
no action
commands, the applet is removed when you
exit configuration mode.
