This package adds a dashboard to your developer section in the umbraco backend. Once installed you can view real time umbraco log.
Basically the package makes use of signalR and a log4net appender to append realtime logging to your browser.
The installer will put a bunch of dlls in your bin and a usercontrol and it will update your log4net config and dashboard.config.
After installing there is one manual step that is required namely update web.config you need to update your umbracoReservedPaths key and add ~/signalr/hubs to the end so that its ignored by umbraco http module.
If after installation you don't see any logging then try using firebug or chrome debugger to see if there are any errors. If you get a HTTP 500 Error for url ~/signalr/hubs if you browse to the signalr/hubs page in a new tab then this should provide a detailed error message to help you debug it.
