I have noticed that Logstash creates weird files in my users home directory when I run it. The files created are empty, and they are named based on values given to input plugin settings such as "beginning" as a value of "start_position", & ["value1" "value2", "value3"], as values from an "add_field" setting. So the file names appear as "beginning", "value1" "value2", & "value3" under the user's (User running Logstash) $HOME directory. What causes this and how can it be fixed. Thanks in advanced, Chrome.
