Event Severity Issues in ControlUp DEX Console
A user created triggers for "Black Hole Machines" and "Registration Failures" but noticed the event severity was only showing as Informational in the DEX Console. They asked for assistance in changing the severity and shared a screenshot. However, it was confirmed that the severity cannot be changed at this time but may be considered in the future. The user wanted to use this value for reporting dashboards and trends. Support was following up on the issue and confirmed that the severity cannot be changed and all triggers will still create an event, regardless of the register event action configured. The trigger was originally set up to send a webhook to Google Chat, but this was changed to a PowerShell script triggered through Script Action to create ServiceNow incidents in the future. There is no way to define the severity of the event at this time.
