"count"
Step 5
Specifies the action to be taken when an EEM applet is
triggered.

Embedded Event Manager Applet Configuration Examples
The following examples show how to create an EEM applet for some of the EEM event detectors. These
examples follow steps outlined in the Registering and Defining an Embedded Event Manager Applet, on
page 1696.
Application-Specific Event Detector
The following example shows how a policy named EventPublish_A runs every 20 seconds and publishes an
event type numbered 1 to an EEM subsystem numbered 798. The subsystem value of 798 specifies that a
publish event has occurred from an EEM policy. A second policy named EventPublish_B is registered to run
when the EEM event type 1 occurs with subsystem 798. When the EventPublish_B policy runs, it sends a
message to syslog containing data passed as an argument from the EventPublish_A policy.
event manager applet EventPublish_A
event timer watchdog time 20.0
action 1.0 syslog msg "Applet EventPublish_A"
action 2.0 publish-event sub-system 798 type 1 arg1 twenty
exit
event manager applet EventPublish_B
event application sub-system 798 type 1
action 1.0 syslog msg "Applet EventPublish_B arg1 $_application_data1"
