The Alarm Event Propagation implementation is limited as detailed below:

• The only alarm properties that are currently propagated are: Name, Priority and Notes.
• Alarms over the GAN from an Engine gateway where alarms were forwarded over MQTT from Transmission is not currently supported
• Alarm pipelines and notifications exposed across MQTT along with alarm data is currently not supported
• Alarm Status Table filtering to a Sparkplug Group/Edge and/or Device ID is not fully supported
  • In release 4.0.28 Sparkplug IDs were added to the source and display path of alarms at MQTT Engine to allow for Alarm Status Table filtering to Sparkplug IDs
  • From release 4.0.28 onward, MQTT Engine supports explicitly inserting alarm events into the Alarm Journal on arrival
