Using PowerCLI in the vSphere Web Client
There is a new tool available at VMware Labs website, that can integrate VMware PowerCLI with the vSphere Web Client, so you can make Reports or actions.
The tool/Plug-in can be found here: https://labs.vmware.com/flings/poweractions-for-vsphere-web-client
There are also a VMware Blog article about how to use this: http://blogs.vmware.com/PowerCLI/2014/09/poweractions.html
