DNS Plugin Logs

I got started configuring some DNS reverse lookups for my firewall logs.

I am seeings these in the logs:

[2017-02-07T10:11:18,041][ERROR][logstash.filters.dns ] DNS: timeout on resolving address. {:field=>"destination_dns", :value=>""}

While I get that reverse resolution is going to fail, is there way to have the plugin NOT log the failures?
