I have a directory contains too many logs which were named as log-YYYYMMDD ranging from 5 years ago to now.

I do not want Logstash to parse the old logs. So I need something like this

```python
input {
  file {
    param => { "today" => "datetime.now()" }
    path => "/path/to/log-{%today}"
  }
}

```

Or any other ideas to solve this problem?  
Thank you for your help.

Use the file input's `ignore_older` option to ignore old files.
