Latest version (3.0.7) of Oracle DB extension shows zero values for all size metrics for non-cdb databases (all of customers dbs are non-cdb).
Problem is that those metrics are retrieved as part of multitenancy featureset (enabled here), which uses V$PDBS for data extraction (metrics like TOTAL_SIZE, MAX_SIZE, ..). For non-cdb databases however, this view doesn't contain any data.
Is this expected behaviour of extension metrics for non-cdb databases? Isn't there any other db size metrics source for non-cdb databases?
