PDI logs all of the executions of a transformation. By default, the level of the logging details is basic, but there are seven possible levels of logging, ranging from Nothing at all to Rowlevel (very detailed), which is the most detailed level of logging. You can change the level of logging as follows:

• If you will run a transformation, in the Execute a transformation window, before clicking on Run, select the proper option:

• If you are previewing a transformation, instead of clicking on Quick Launch, select Configure. This will show you the Execute a transformation window. In this window, choose Log level, and then click on Run.
