EntityAlarmStatus
Represents the possible values of alarm status. An Alarm [RFC3877] is a persistent indication of an error or warning condition. When no bits of this attribute are set, then no active alarms are known against this entity and it is not under repair. When the 'value of underRepair' is set, the resource is currently being repaired, which, depending on the implementation, may make the other values in this bit string not meaningful. When the value of 'critical' is set, one or more critical alarms are active against the resource. When the value of 'major' is set, one or more major alarms are active against the resource. When the value of 'minor' is set, one or more minor alarms are active against the resource. When the value of 'warning' is set, one or more warning alarms are active against the resource. When the value of 'indeterminate' is set, one or more alarms of whose perceived severity cannot be determined are active against this resource. A value of 'unknown' means that this resource is unable to report alarm state.
