"...We have an updated tracing package now available from the Microsoft Download center page for Forefront Unified Access Gateway (UAG) Tracing Symbols. This new trace package includes formatting for all UAG versions through Service Pack 3 Rollup 1 and includes the SP3 enhanced context tracing to more easily filter trace data per session.
Forefront UAG tracing can be run on the Forefront UAG server and on client endpoint devices connecting to Forefront UAG resources. You configure trace settings, start tracing, reproduce scenarios that require troubleshooting, stop tracing, and then convert the binary tracing output to text using the provided format files.
This download provides the following:
• A set of .tmf files in a zip file. These .tmf files can be used to convert binary trace files on the Forefront UAG server, and on client endpoint devices.
• A EULA license
• A document with instructions for configuring and running tracing
