Alarm clearing

Alarms can be cleared:

  • automatically when the necessary conditions are met,

  • manually by a user.

Automatic clearing

An alarm is automatically cleared if the object does not have alarm generation conditions, when this object transitions into the state, alarm severity of which is not set.

By default, the alarm severity is set in the following states:





If alarm generation conditions are set, an alarm is cleared when the conditions of its generation are no longer met.

If the alarm generation condition is not met due to absence of data in the system, the previously created alarm will be cleared and the new one with the MAJOR severity and No data text will be created.
If additional clear conditions are set, these conditions must be met as well in order to automatically clear the incident.

Manual clearing

Any alarm can be cleared manually by a user via the alarm context menu - the Clear option:


With manual clearing, alarms forcibly transmitted into the CLEARED state.

For alarms, created with alarm generation conditions, the state of the object, which caused the alarm, is not changed.

For alarms, created with state change conditions, there is the window to change the state of the object, which caused the alarm:

The functionality of state change on manual clearing of alarms is useful for objects with "event driven" probes, for which the condition to transit to an alarm state is any incoming event. For instance, the SNMP Trap probe.
When new data arrives to the object, the state, which has been applied on manual clearing of the alarm, will be changed according to state change conditions.
