RVTools, from Robware, offers graphical reporting on vSphere hosts and VMs. This free tool is reminiscent of an Excel spreadsheet: It organizes your vSphere resources into columns and tabs. This lets you discover which VMs have virtual CDs connected and which VMs have outdated tools. It also serves as an inventory of all VMs. You can even export the information as delimited files for further manipulation and analysis. RVTools gives you a view of all infrastructure data without piecing it together within vCenter or running multiple scripts. With ThinApp, you can also virtualize RVTools on a thumb drive.
