Alarm changed
This event enables the monitoring of all or specific alarms. Please note that only the alarms that are enabled in
the source setup of a module are useful. The full list of available source related alarms can be found in the iStu-
dio user interface or can be requested with the getlistalarms command. A few examples of alarms are
videoloss, videoblack, videowhite and audioloss.
Furthermore the module related ntpsynchrolost alarm is available. It refers to the module not to a source and is
therefore addressed as source no. -1.
