($variable_name) instead of entering a specific value for an argument. EAA will replace the variable

name with the variable value when it performs the action.
To change the value for an action argument, you modify the value specified in the variable pair instead

of editing each affected monitor policy.
EAA environment variables include system-defined variables and user-defined variables.

System-defined variables

System-defined variables are provided by default, and they cannot be created, deleted, or modified by
users. System-defined variable names start with an underscore (_) sign, and variable values are set

automatically by the system depending on the event setting in the policy that references the variables.
System-defined variables include the following types:

Public variable—Available for any events.

Event-specific variable—Available only for a specific type of event.

Table 30

shows all system-defined variables.
