Creating and Managing Alert Severities


The alert severity is the level classification set for different alerts according to the severity and processing priority of the event. Alert severities can be used for filtering alert messages and analyzing historical alert data. By numbering or describing the severity of filtered alerts, you can respond to events with different states in a timely manner.


For a specific domain asset, the alert severity definitions are typically found in its instructions. If needed, you can also customize the definitions according to your business needs or best practices in the domain.


For example, the temperature of a transformer can be divided into 3 levels according to business needs, so 3 alert severities can be set:

  • If the temperature exceeds 85℃, there is a significant safety risk for the transformer and the alert severity can be set as “fault”.

  • If the temperature of the transformer drops to the range of 84-55℃, there may be a risk and the alert severity can be set as “warning”.

  • If the temperature of the transformer drops to less than 54℃, the alert severity can be set as “message”.


The following shows how to create, edit, and delete alert severities.
