Add a feature to filter/group by host so we can easily see which databases are contributing the most to a performance issue at the host level. We can currently see a resource metric for CPU usage by db on a single database, it would be useful to see that metric across all databases on a particular host. Other resource metrics would also be useful, like memory usage by a DB that can be compared at the host level. I haven't looked at the VM monitoring tool but I imagine this functionality is already available there. I currently do this via OS tools, like top, prstat, etc., as well as Best/1 has a rudimentary functionality based on assigning OS processes to "workloads".
