The present invention extends to methods, systems, and computer program products for validation configuration of distributed applications. Embodiments of the invention provide a system framework for identifying root causes of configuration errors and best-practice incompliance of distributed applications. The system framework provides both platform provider and customer a powerful and consistent method to create, extend, and utilize a tool that simplifies the configuration troubleshooting experience. Using the system framework, a user is able to access more information about applications and to troubleshoot multiple applications at the same time without having to load or activate any of the applications. In addition, users are able to add custom rules to identify commonly occurring configuration problems.
