Hi Prajakta,

You could possibly use the Exec source with the "tail -F /path/to/file"
command. One limitation of this approach is that it does not maintain any
state so you won't be able to resume/restart from a location within the
file. To address those cases, it may be necessary for you to write your own
scripts etc.

Regards,
Arvind
