Log files

DITA Open Toolkit

Log files

When you run the DITA-OT, key information is logged on the screen. This information can also be written to a log file. If you encounter a problem, you can analyze this information to determine the source of the problem and then take action to resolve it.

The logging behavior varies depending on whether you use the dita command, DITA-OT command-line tool, or Ant to invoke a toolkit build.
dita command
By default, only warning and error messages are written to the screen. If you use the -v option, logging will be more verbose and informative messages are also written out. The -l option can be used to write the log messages into a file.
Ant
By default, status information is written to the screen. If you issue the -l parameter, the build runs silently and the information is written to a log file with the name and location that you specified. (You also can use other Ant loggers; see the Ant documentation for more information.)
Command-line tool
Status information is written to the screen and the log file. The log file name contains the input file name and transformation type; by default, it is located in the output directory. If you issue the /logdir parameter, you can specify a different location for where the log file is written.
