Managing Alarms
• Delete - a user can Delete an Alarm object which has the effect of deleting
the object from the set of Listener Base Records, and of deleting all Alarm
objects associated with that particular Listener object in the Alarms Database.
Note that a Delete can only be done to an unassigned Alarm object or to a
closed Alarm object.
As noted above, some of the user actions cannot be performed depending on the
current state of the Alarm object. This behavior is enforced by the AlarmTracker
Client UI. Also, depending on the user's rights (see User Rights, page 4-15), not
all options will be available to every user.
Clear and Delete
It is important to understand the distinction between the Clear and Delete user
actions.
Clear is used for an Alarm object when a support person determines that the object
is, in fact, up, but for some reason the clear Event was never received. This is, in
a sense, a "manual override" for a clear Event from the device. When a user Clear
is done, the Alarm object is closed and the state of the underlying Listener object
becomes Up. The Alarm object remains in the Alarms Database and can be viewed
in various AlarmTracker Client views.
By policy, a user Clear can only be done on an Alarm that is Down and
Unassigned. If the Alarm is currently Assigned or Excluded, the user must first
Unassign or Include it before Clearing it. This is a policy decision enforced by the
AlarmTracker Client UI.
Another policy decision is that single-state Alarms (Application Errors are
considered single-state Alarms) cannot be Cleared. They must be Deleted.
A user Delete operates in a different way. A Delete results in the object being
deleted from the Listener Base Records, and in the deletion of all Alarm objects
associated with the Listener object. Thus, when you delete a particular Alarm
object, you may, in fact, be deleting multiple Alarm objects from the database. All
Alarm objects associated with the Listener object are deleted from the LGMapper
Alarms Database. They will be removed from any Alarms display (you may still
see earlier Events in the EventsBar), but you will no longer see these Alarms.
