Hi, Im filtering some CSV files,and Im getting some nil fields, and if some field is nil the entire message is worthless, so how can I ignore the entire message if one of the fields value is nil?

Thanks!

I end up using ruby

```auto
ruby {
          code => "event.cancel if event.get('ifInUtilizationPct').nil?"
        }

```
