Notification sequence:
Notifications (or traps) are identified with a unique id number (see trap description, Appendix A). They
include common fields but also specific fields to detail the reason and the context for the notification. The
common fields are:
o
SystemType: GoldenEagleAM
o
SerialNumber: unit serial number
o
VersionSoftware: embedded software number version
o
SequenceNumber: trap sequence number (this value is incremented for each new trap)
When an alarm is triggered, a TRAP is sent with the following values:
-
channelType: 8 (AM)
-
frequency: frequency in kHz x10 (530 for 1710 kHz)
-
channelId: row number of the station in the monitored channel list
-
channelName: station name
-
alarmStatus: integer indicating the alarm state: 1 for the alarm beginning
-
errorDateTime: date and time of the beginning of the event
-
eventStartDateTime: date and time of the notification being sent (Note: this date includes
triggering time or Timeout)
-
severity: event severity as set the notification configuration page
-
readValue: observed value (converted into integer)
-
referenceValue: reference value for comparison as set in configuration pages
-
transmitterName: name of the transmitter associated with this station
-
networkName: network name associated with this station
When the alarm is over, the same trap is sent with alarmStatus = 2, and the end time in errorDateTime.
Case of alarms ‘closed by hierarchy’
When an alarm with a high hierarchical level is triggered, the state for each lower hierarchical level alarm
changes
to ‘CLOSED’ and a notification for ‘closed by hierarchy’ is sent. As an example, if an AFLOW alarm
is active and the RFLOW2 alarm gets triggered, an AFLOW trap is sent with an alarmStatus value of 3
(closed by hierarchy).
