 Description  « Hide
Subject says it all. The AST doesn't have an appropriate attachment linked, thus only the dbb-level counter gets incremented. But statistics for MON$DATABASE is not "global" in the monitoring, it reports only the local attachment. Hence we don't see a major part of those writes in the MON$ tables at all.
