List of alarm providers (plug-ins) in a GSM Alarm Browser
When you create a new alarm provider, an instance of the plug-in starts running on the
Application Server, and begins publishing its alarms to the GSM. There are two types of alarm
providers: single instance and multiple instance.
Single-instance Alarm Providers
For certain plug-ins, once an instance has been created on the Application Server, the plug-in
name is removed from the list of alarm providers. An example of a single-instance plug-in is
the Router plug-in, since only one instance is required to monitor all the routers on a local
network.
Multiple-instance Alarm Providers
Most alarm provider plug-ins can have multiple instances, each monitoring a specific device
on a network. For example, multiple instances of the Kaleido plug-in might be running
simultaneously, each one assigned to a different Kaleido frame. Another example is virtual
alarms—every virtual alarm is an instance of the virtual alarm plug-in.
A list of currently active alarm providers can by viewed in the Admin > Alarms tab of the GSM
Alarm Browser.
