Alarm Refefence Format¶
Alarm reference is a kind of distinguisher used for direct alarm addressing and for deduplication. Open alarms with same references are virtually the same and will be handled as one alarm.
References are assigned into the namespaces, each with unique prefix:
e- Event Reference
g- Group Reference, including
g:m- Maintenance Reference
g:u- User Reference
p- Ping Reference
Generated internally by correlator service during the processing of events.
Simple format (without variables):
e:<managed object id>:<alarm class id>
Complex format (with variables)
e:<managed object id>:<alarm class id>:<var1>:...:<varN>
e- Event reference namespace
<managed object id>- ID of related managed object
<alarm class id>- ID of related alarm class
<varN>- Appropriate alarm class
\will be replaced with
:will be replaced with
Alarm classes without additional
reference variables will raise only one alarm per class.

Created automatically for all active maintenances.
<maintenance id>- ID of the maintenance record.
Created by user to group and hold alarms in work.
<user id>- ID of the holding user.
ping service to address
