Monitoring your apps from a Windows Azure client

Monitoring goes beyond checking for OS uptime. You need to make sure that your apps are ready to do what users expect from them. The Really Simple Monitoring is both a methodology (domain-driven monitoring) to strengthen complex apps and an XML format used to expose the internal state of your apps.

Lokad.Monitoring is a web client designed for Windows Azure that consumes RSM endpoints exposed by 3rd party apps, and produces web reports out of the collected information.
