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=>"104.244.43.135"}
While I get that reverse resolution is going to fail, is there way to have the plugin NOT log the failures?
