Sorry if this a total rookie question but..  
**Scenario** : I have random multiline log messages that have anywhere from 1 to 100 IP addresses in them. The IP's are sporadic and don't always follow a single pattern. Ie. They don't always follow a single comma, etc.

**Goal** : Match all IP's and output them to a single field as an array.

**Question** : Using a grok filter I can match the first result but it then stops processing. Is there an easy way to match each IP without having 100 match statements and 100 fields?

**Thoughts** : loop the single match statements? Output the original message to a new field and then use mutate to remove anything that **doesn't** match an IP.

Any insight is appreciated.

Thanks!

(Apologies for bad formating, I'm writing this from my mobile)

Does [this open issue](https://github.com/logstash-plugins/logstash-filter-grok/issues/86) match what you are looking for?

Unfortunately that means it is currently not possible, so you may need to use a ruby filter.
