The event rules in Traffix Manager fall into two broad categories:
■
Security — An event is generated when some aspect of network
security may have been compromised.
■
Traffic — An event is generated when a significant change in traffic
patterns is detected.
The various types of event rule are discussed in more detail in the
following section.
Traffix Manager provides a number of predefined event rules that cover
common network issues. You can also add your own event rules, edit
existing event rules and enable/disable them, as described in
“Configuring Event Rules” on page 75 .
The final part of this chapter suggests ways of using the various types of
event rule to implement strategies for managing your network.
