                                           @QueryParam(value="l")

                                    throws IOException

Tails the file with name file.

If the parameter fromLine is defined, the tail starts from this defined line and the parameter numberOfLines is ignored.

If the parameter numberOfLines is defined, this maximum number of lines is returned from before the end of file, just like tail -f -n [number].

Parameters:

file - name of the file to tail from.

fromLine - start line to tail from.

numberOfLines - number of line to tail from the end of file.

Returns:

Response with a List of LogLineDTO containing the tail information.

Throws:

IOException - if there is an error when reading the log file.
