Logger

Logs each feature to the translation log at the specified severity. All attributes and geometry of the feature will be output.

Limits can be placed on both the number of features that will be logged, and the number of coordinates that will be logged per feature.

Usage Notes

  • An alternate way to see the attributes and geometries of features is to route them into an Inspector transformer, which will display them in the FME Data Inspector.
  • The Logged port should be used to guarantee that the features are logged before they are further processed. If a Logger does not output features, the logging may occur after other transformers have completed. The logging may not even take place if the workspace terminates early.
  • Null values will be logged as "is <null>", whereas strings whose content is "<null>" will be logged as "has value '<null>'".
  • To quickly attach Logger transformers: right-click on one or more selected reader feature types and choose Connect Loggers.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
