The present disclosure includes descriptions of various aspects of unified communication (UC) systems, including UC management and analysis systems and related tools and techniques. Described systems, tools, and techniques are adapted for enhanced UC data capture, analysis, and reporting; enhanced UC monitoring services; and a user survey service that can be used for conducting user surveys related to UC services. Embodiments disclosed herein include a process for determining location-based quality metrics; a process for calculating weighted availability in a computer system (e.g., a UC system); a process for generating a set of test rules based on automatic inspection of a UC topology; a process for setting a response priority for a rule failure based on classification of the failure; and process for executing a survey instance for users of a UC system based on presence information.
