Alarm Detection helps you define the criteria for the generation of alarm messages. You select a condition, or combine a set of conditions, that within specific limits, generate an alarm message. To monitor the system alarms, you use the Web Interface. Note that you can deliver alarm messages to SNMP monitoring systems, as well. An alarm can be in one of two states: new or closed. An open alarm is an indication of a certain occurrence or situation that has not been resolved yet. A closed alarm is a resolved indication.
To create a new Alarm Detection configuration, click Build → New Configuration in the Desktop, and then select Alarm Detection from the Configurations window.

To define a variable to use in the APL code, see the APL Reference Guide, and the section below, Workflow Alarm Value for further information.
Defining an Alarm Detection
To define Alarm Detection, you must Configure the Alarm Detection and Add an Alarm Condition.
An Alarm Detection definition is made up of:
A condition, or a set of conditions, see the section below, Alarm Conditions
An object such as host, pico instance, or workflow, that the alarm should supervise
The parameter that you want the alarm to supervise, for example, the Statistics value
Time and value limits of supervision
To create a valid alarm detection configuration make sure that:
The Alarm Detection includes at least one condition.
Two conditions within an alarm guard the same object: host, pico instance, or workflow.
Two conditions are set to the same time interval criteria.
