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 iC Navigator are not handled by the GSM. (These are the JINI statuses.) These are not the same as GSM statuses. For example, iC 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 Grass Valley 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.
NOTE: Some applications may represent alarm states differently or use different color schemes. |
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).
Color scheme and hierarchy of alarm statuses
Color | Meaning |
White | No ID assigned to the link - first status on the page before changing to another color Waiting for the GSM to reply such as a slow VPN connection (a new client service) |
Green | Normal - an operation status driven by the service |
Yellow | Warning - an operation status driven by the service - usually not used |
Red | Error |
Gray | Unknown - lost connection. The default status for a new alarm that has been added to GSM before its state is known is gray. Therefore if the initial state of the alarm is also gray, there is no need to update the GSM status (but doing it anyway won't have any adverse effect either). |
Blue | Non existent: this is a pseudo-status representing an alarm that has been removed (or was never added). You should never see it in the GSM tree, but you'll see it in client applications that listen to specific alarms and the log viewer. When the device starts up and sends its initial state, the previous state box should be initialized to blue. |
Black | Disabled at the source. Some devices have the ability to deactivate some alarms on the hardware itself; these alarms will show up as black when they are deactivated in this manner. |
