I'm having the `logstash` configuration where it picks up the log files from a folder and pushing it to the index.

This is how my `input` looks like:

```
  input {        
    	file {
    		path => "/home/chamith/work/ELK/sample_logs/gdcb_logs/GDCBAdapter_tdr.log*"
    		start_position => "beginning" 
    		ignore_older => 0 
    		sincedb_path => "/dev/null"
    	}
    }

```

I've tried cron `schedule` for `jdbc` input, but then I'm quite unsure of doing it for file types.

How can I have a scheduler in the above to check for any new log files or whether any new rows have been added to a log file time to time? Or does the `file` plugin do this automatically ?

Any help could be appreciated.

The file plugin does this by default. There are a couple of options that allows you to fine tune the behavior.

What could be the options ?
