Hi, I believe you are talking about having the FVE dashboard embedded as a tab in vSphere client. That was a great feature in FVS, but it has not been added to FVE. I will discuss it with the FVE team, as it could be a good addition. For the time being, you could use: vSphere Plugin Wizard  to manually create the plug-in.   Regarding the documentation links, I am sorry to hear they are broken, please contact Support so they can look into it. For the time being, here is the link to the online documentation: [URL]
Is it possible to register foglight within vcenter?  It is fairly simple in foglight standard.  Just tick a box.  I can't find any similar setting in foglight enterprise.  The links to the user guides all errror out as well.
