## Enum Description

These constant strings can be used as parameters in user-specified email subject and body templates as well as in scripts. The action processor in VirtualCenter substitutes the run-time values for the parameters. For example, an email subject provided by the client could be the string: `"Alarm - {alarmName} Description:\n{eventDescription}"`. Or a script action provided could be: `"myScript {alarmName}"`
