To generate configuration overview report, you need to open Veeam ONE Reporter -> Templates -> Infrastructure overview report. Please take a look at our "Dashboards and Reports
" document, that should guide you through this process: http://www.veeam.com/veeam_one_v6_dashb ... rts_pg.pdf
If you're referring to performance overview, then in v6 there is no single report, only dashboards and smaller reports. Thanks!
