Looking to run a report that will help us see change rate on Unity NAS data. What would be the best Live Optics report to see this??

  The Unity collection would be best for this.  However, you would need to run the collection back to back:

  • Point the Live Optics collector at the Unity array and collect N days of data
  • N could be 1, 2, 7, etc
  • Wait N days
  • Run the collector again and point at the same array collecting N days of data

  You now will have two projects.  Download the Excel files for each project, and then compare the Filesystems tab which has a Size Used column.

  The deltas of the Size Used / N days is the change rate.

  At first, I thought that you might be able to run the collector against the Unity array and select a day from 30 days ago, and then run a second time with the most recent day.  However, the collector grabs the volume capacity information from the latest value - not from the historical performance data.  So, you must run twice with some interval of N days in between the two collection runs.
