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 56
EAA framework
Event sources
Event sources are software or hardware modules that trigger events (see
).
For example, the CLI module triggers an event when you enter a command. The Syslog module (the
information center) triggers an event when it receives a log message.
Event monitors
EAA creates one event monitor to monitor the system for the event specified in each monitor policy.
An event monitor notifies the RTM to run the monitor policy when the monitored event occurs.
RTM
RTM manages the creation, state machine, and execution of monitor policies.
