Alarm DefinitionsΒΆ
Yamcs supports the XTCE notion of alarms. Based on the value of a parameter, Yamcs assigns a monitoring result to each parameter.
An alarm check is performed when any of these applies (in order):
The condition for a context alarm is satisfied (if multiple, the alarm specification for first matching context is applied).
There is an alarm specification without a context (default alarm).
The monitoring result can be:
null (no alarm specification applies)
IN_LIMITS (an alarm was checked, but the value is within limits)
WATCH
WARNING
DISTRESS
CRITICAL
SEVERE
