Defining Alarms
EPICenter Reference Guide
115
The Alarm Definition List shows all the current alarm definitions. This list shows the following
information about each alarm:
To view the settings for an individual alarm, select the alarm.
The detailed definition of the selected alarm appears in the fields below the alarm list. In addition to the
basic properties shown in the Alarm Definition list, these fields show additional properties such as
whether pattern matching should be used on event data, or whether the event must occur more than
once before the alarm is triggered. These basic properties are defined in detail in
“Defining the Basic
Alarm Properties” on page 117 .
Below the basic properties, two text fields show the alarm actions (if any) defined for the alarm, and
scope of alarm.
Alarm Actions are functions that the alarm system executes when an alarm occurs, in addition to logging
the occurrence of the alarm. By default the predefined alarms have no actions defined for them (other
than logging). Alarm actions can include sending e-mail, sounding an audible alert, running a program
or executing a Telnet macro. For the predefined alarms, an alarm event creates an entry in the Alarm
Log, but no other actions occur. You can define additional actions for any of these alarms. Alarm
Actions are discussed in more detail in
“Defining Alarm Actions” on page 121 .
The Alarm Scope defines which devices can trigger an alarm. The predefined alarms are scoped by
default for all devices and ports. Thus, a trap received from any port or any device triggers the
corresponding alarm. You can modify the scope of any of these alarms. Alarm Scope is discussed in
more detail in
“Defining the Alarm Scope” on page 119 .
