Explicit and implicit feedback information, that is indicative of an issue in a deployed computing system, is collected. Information identifying attempted resolutions for the issue is collected as well. A knowledge base is generated that identifies issues and successful resolutions for those issues. During runtime, issues are detected, either explicitly or implicitly, and the knowledge base is accessed to determine whether a resolution has already been identified. If so, it can be proactively provided to the computing system to address the issue.
