Alarm States
The current state of each alarm is shown as an icon next to the alarm name. Each possible
alarm state is represented by a color where the states are dynamically updated.
The statuses in iControl Navigator are not handled by the GSM. (These are the JINI statuses.)
These are not the same as GSM statuses. For example, iControl Navigator can run without a
GSM and can provide statuses but not the same type when a GSM is running.
All iControl alarm notifications are managed through a central system called the General
Status Manager (GSM). For purposes of load sharing on the client side, alarm notifications
from multiple distributed GSMs may be managed by the multi GSM Manager which computes
the virtual alarm, gets its status and dispatches the alarm status to the client
For example, a Miranda FRS-111i frame synchronizer reports on six operating conditions
(e.g. Video input presence), and generates a seventh overall status alarm based on the state of
the other six alarms.
When the system starts for the first time the GSM appears on the network while the device is
already running, the device is expected to add its alarms to the GSM and to send their status.
In that case, both the previous state and next state of the alarm should be initialized to the
current state of the alarm.
The following list indicates the color scheme and hierarchy of alarm statuses. The alarm states
are positioned from greater value (top of list) to lesser value (bottom of list).
