SQL Server logging fields

Published: January 11, 2010

Updated: June 1, 2010

Applies To: Unified Access Gateway

Forefront Unified Access Gateway (UAG) can log events to a SQL Server database using the Forefront TMG logging mechanism (by default Forefront TMG is installed on the Forefront UAG server). Events can be logged to a local SQL Server Express database running on the Forefront UAG server, or to a remote SQL Server database. Forefront UAG events are logged to the Forefront TMG Web Proxy log. When configuring SQL Server logging in the Forefront TMG Management console, you can specify which log fields should be written to the SQL Server log. For instructions, see Logging to a SQL Server. This reference topic provides information about the fields available in the Forefront TMG Web proxy log.

Forefront TMG log fields

Log fields consists of the default Forefront TMG Web proxy logs fields, and a number of Forefront UAG-specific log fields. For a complete list of Forefront TMG log fields, see Web proxy log fields in the Forefront TMG TechNet library. Forefront TMG log fields, and specific Forefront UAG log fields, are summarized in the table below.
