According to the documentation, the Database Node CPU Usage, found under Metrics in the Mendix Platform, is not a currently supported metric that can be sent to DataDog. Mendix Support suggested that we come here to request this metric to become a supported metric for DataDog, to ensure a clearer picture of the database health.
We had an instance in May where the DB node CPU usage was capped at 100% for a long period of time . We would like to create monitoring and alerting around this to ensure it is resolved immediately, if it happens again.
 Screenshot of maxed CPU usage below, example of what we would like to see in DataDog:
also one of the key metrics for us!
This would certainly help us to be more proactive. Infinitely better than waiting for customers to complain about performance.
