Description


With this change, the Cumulocity platform will raise an alarm when the Messaging Service fails to process a message.
Issues reported in this way require user action to be resolved. Currently, this only happens when publishing to a Notifications 2.0 subscription fails because the underlying topic has reached its backlog quota limit. More information about Notification 2.0 backlog quotas can be found in the documentation.
