Trace Viewer Application

The Trace Viewer application allows you to monitor the content and parameters of driver messages and VTS-related network traffic as it occurs. The collected data is also logged to standard Access database files for later viewing.

There are three components involved in tracing:

•      The communications to be traced. Each message source, (driver tracing, RPC diagnostics and SOAP message tracing) has its own format and therefore is stored in its own database.

•      The module that collects and writes the actual data to the database. This is DBTrace, a system-level module that maintains live communications with the Trace Viewer.

•      The viewer. This is the Trace Viewer application, where you can select, filter and display the communications data.

 

Trace files are regular Microsoft Access .MDB files. These are stored in the TraceFiles subdirectory within the VTS installation directory.

These files are deleted as they age, with the default set to 30 days. If you wish to modify this setting, you may do so using the DbTraceDaysToPreserve variable in Setup.ini.

Trace files can contain additional tables that assist in the interpretation and filtering of their data. This means that the files can be exported into another environment and can still be interpreted correctly.
