When an ASM instance (or cluster) that serves multiple databases, Spotlight will show the total ASM statistics across all databases. So the ASM drilldowns in each Spotlight connection would be exactly the same.
Like the I/O per second metric in Oracle RAC homepage, it reflects the total I/O for the ASM instance , which includes ASM activities such as internal re-organization and I/O operations for other databases configured to access ASM on the same node.
