OEM Report: Last 6 month Database Space Usage and Growth [2]

Hey,
So I see you liked the last OEM Report post. But some have asked me for a table with all databases space usage something like a summary table for executive view, once the last report give it by database, right…

Here it goes:
– I hided the target names for safety, but check on the last column “AVG 6-m Growth”. This is the one you want.
– This obviously needs to be in another Report, once no DB filter is present. So, here is an exame of table and the code:

And let me ask you: Would you like to have this view from the ASM Perspective? Like this?

ASM-Growth

Great, right?
The codes for this:
