There may be a few misconceptions about what "instrumentation" is in relation to the Quest Foglight UEM solution. For those in the dark about this concept, basically instrumentation gives you the "client perspective" when measuring end-user performance and availability of your web-sites. Client-side perspective is important when there is a lot of "stuff" in between your end-user and the application infrastructure, such as a content delivery network (CDN) like Akamai or Limewire. Since your appliance-based monitoring from Foglight lives in YOUR infrastructure not at the CDN, instrumentation can give you that "last mile" of performance information that has to be otherwise mathematically derived.
With the Foglight product consistently growing in features, your end-users will soon be instruments in your orchestra of complete application performance monitoring.
