Alarm Failures in Hyper Alarm Server (6686)
Issue
Hyper Alarm Server does not generate any alarms. TraceWorX logs this error-level (800) message repeatedly:
NullReferenceException : Object reference not set to an instance of an object.
This might be a new configuration, or one upgraded from a previous version. If it was upgraded, it worked fine in the previous version.
Workaround
- Stop Hyper Alarm Server.
- Check each of your alarm types and make sure they have a field with a field type of severity. If there is no field of type severity, add one.
- In Workbench, expand Alarms and Notifications > Hyper Alarm Server > Product Configuration > System Settings, and locate the Alarm States Storage section. If alarm states storage is enabled, go to the location listed for storage directory and delete the contents of that folder.
- Start Hyper Alarm Server.
