Hi
In Flume-ng is there any way using exec (tail -F) as the source to get
only the new lines which are being added to the log file ?
(i.e. there is a growing log file and we want to transfer all the logs
using flume
without duplication of logs)
I understand if something fails and as tail doesn't maintain state we
will have duplicates.
But we are not considering failovers as of now.
So I think "tail -F" is useful only in scenarios where sink or any
intermediate
agent can remove duplicates. Is it correct?
But as tail looks like quite a popular source in flume I thought I might
be missing
something.....
Presently using "tail -F <file>" as the source to read from the log file
leads to
scenarios like this:
1. If file has not changed for a while, but tail still tails file every
second and then prints the same lines again (depending upon -n option)
2. Even if file grows then using tail we can't quite control which lines
we want?
