This is a nice report, but doesnt seem to work as the result shows negative optimization on the Riverbed Steelhead interfaces. I looked at the SQL in the custom report and see that the contributor using IN_TotalBytes and IN_TotalPkts for POST interface results. Shouldn't he be using IN_Totalxxx on the pre-opt (LAN) interface and OUT_Totalxxx on the post-opt (WAN) interface? I tried this and the results are better- the % optimization is positive value, but a small number. Is this all that needs to be fixed? Anyone else fixed this, as I need to be sure I'm doing the right thing.
