                  Tracing level represents the amount of information that informatcia server writes in a log file.
Types of tracing level
Normal
Verbose
Verbose init
Verbose data
When you configure a transformation, you can set the amount of detail the Integration Service writes in the session log.
The session log tracing levels are:

1. Normal: Integration Service logs initialization and status information, errors encountered, and skipped rows due to transformation row errors. Summarizes session results, but not at the level of individual rows.

2. Terse: Integration Service logs initialization information and error messages and notification of rejected data.

3. Verbose Initialization: In addition to normal tracing, Integration Service logs additional initialization details, names of index and data files used, and detailed transformation statistics.

4. Verbose Data: In addition to verbose initialization tracing, Integration Service logs each row that passes into the mapping. Also notes where the Integration Service truncates string data to fit the precision of a column and provides detailed transformation statistics.
By default, the tracing level for every transformation is Normal.
