-Re: Documentation refers to adaptor "FileTailer" which does not exist

The FileTailer adaptor is located in a subpackage called filetailer.
Try this command instead:
add fileTailer.FileTailer /tmp/foo 0
Sorry about the documentation error. In addition, I would recomend using
add fileTailer.CharFileTailingAdaptorUTF8NewLineEscaped /tmp/foo 0
This supports UTF-8 characters and using new line character as
delimiter to stream log entry.
Hope this helps.
