Monitoring mod_pagespeed
Josh Nichols of Rails Machine has developed a Scout plugin for monitoring mod_pagespeed, Google's Apache 2.x module for performing on-the-fly optimization in the Apache 2 HTTP Server.
mod_pagespeed has several filters that optimize a web page’s resources. These filters combine CSS files, optimize images, and more. mod_pagespeed is still under heavy development (a couple of the filters aren’t working for Josh, including image optimization). These issues shouldn’t impact the plugin’s metric reporting.
