Alarm message
Overview
An Alarm message indicates that a feed in to Darwin has stopped, or has re-started.
Detail
The alarms sent are as follows:
| Alarm | Meaning |
|---|---|
| tdAreaFail | Darwin has detected that no data has been received from a single TD for a period of time |
| tdFeedFail | Darwin has detected that no data has been received from any TD for a period of time |
| tyrellFeedFail | Darwin has detected that its connection to Tyrell has failed |
Each alarm has a unique identifier, and may be cleared with an alarm being received with a 'clear' element and the same unique identifier.
