Could anyone direct me to where I can see the logger.warn statements (specifically the one on line [79 of split](https://github.com/logstash-plugins/logstash-filter-split/blob/master/lib/logstash/filters/split.rb#L79))

I've tried looking at the file generated by:

```auto
bin/logstash --verbose --log log.txt -f PATH_TO_FILE.conf

```

But it doesn't have any of the logger statements although an error occurred...

What version of the split filter are you using?

According to `bin/logstash-plugin list --verbose`

The plugin version is `logstash-filter-split (2.0.5)`

That message is only logged in v3.1.1 and later.
