Snooper is a multipurpose debugging tool for Microsoft Lync Server 2010 communications software. Snooper parses server and client trace log files and makes protocol (for example, SIP and HTTP) messages and traces easier to read. It can also read call details and stored procedure execution reports for errors. In addition, Snooper can display reports about users, conferences, and conferencing servers (also known as multipoint control units or MCUs). You can download this tool and other Microsoft Lync Server 2010 Resource Kit tools from the Download Center.
