Currently the percentage of the database and Listener availability is a whole number (xxx%).
Can it be modified to be displayed as xx.xxx?
It is possible to get the decimal places.
You cannot modify the existing dashboard, but you can create your own dashboard and create a query to get the values as decimal numbers.
We recommend to contact our Professional Service department to get assistance setting up the new dashboard.
An enhancement request has been submitted to get the decimal places by default. (ODB-1224), but the request has been rejected.
