Configuring EAA

Overview

Embedded Automation Architecture (EAA) is a monitoring framework that enables you to self-define

monitored events and actions to take in response to an event. It allows you to create monitor policies by

using the CLI or Tcl scripts.

EAA framework

EAA framework includes a set of event sources, a set of event monitors, a real-time event manager (RTM),

and a set of user-defined monitor policies, as shown in Figure 63.

Event sources

Event sources are software or hardware modules that produce events (see Figure 63). For example, the

CLI module creates an event when you enter a command, and the Syslog module (the information center)

produces an event when it receives a log message.

Event monitors

One event monitor is created for one monitor policy to monitor the system for the event specified in the

policy. An event monitor notifies the RTM to run the specific monitor policy when the monitored event

occurs.
