Within Solarwinds there should be a new page dedicated to the platforms own web servers under /orion/admin/default_orion.aspx
This should have a Red/Green Indicator like the "Polling Engines" page to illustrate if IIS and the site itself is functional. Maybe even provide performance and load statistics. Would also be great if it could be integrated with the IIS services so you could perform an IIS reset on a web server directly from the Orion console
There is currently no way to tell in Solarwinds how many Additional Web Servers you have without delving into the Database or Licensing Page, even then it doesn't show their status. A web server could be down and nobody would even know.
I understand this could be setup by some custom SAM monitoring or similar within Solarwinds, but I feel IIS is an integral part of the platform and should be represented within it by default
