I'm using NXLog to read log files and send to to Logstash. Normally this works fine, but I'm now trying to send logs from a file, where the new events gets added at the top of the file, not the bottom. Now it's not sending anything.

This is from my NXLog config.

<Input file>
Module  im_file
File "C:\\TEMP\\export.txt"
InputType LineBased
Exec $Message = $raw_event;
SavePos TRUE    
ReadFromLast TRUE
Exec if $raw_event =~ /^#/ drop();                    

Is it possible to read from bottom to top?
