please change value to "true" in c:\inetpub\solarwinds\web.config (or any location where your web-site is) for section <add key="HubbleActive" value="true"/>
We recommend to make backup copy of web.config file before making changes and save it to another location (not in a Web-site folder)
would like to know what does Hubble logging help in?
You can enable Hubble using the "Log Adjuster" application (should be available from the start menu), Hubble provides a way to help identify resources which are slow to load. Once enabled all Orion users will see an additional iframe at the top of the page which details for each view as you navigate.
