Unified Aaccess Gateway 2010 introduced a new trace mechanism that is based on Event Tracing for Windows (ETW); a high-performance, low overhead, scalable tracing mechanism that is provided by the Windows operating system. UAG tracing provides detailed failure and debugging information in a binary format. This binary information can be converted into a readable text format using UAG trace symbols. UAG tracing symbols are now available on Download Center. Forefront UAG tracing can be run on the both UAG server, and on client endpoint devices connecting to Forefront UAG resources.
