Hi  
Since this is the #elastic-stack:kibana channel, you might get a better answer in the #elastic-stack:logstash channel. I don't think you can achieve this with grok (unless you know what's the max number of root causes) . But I would try combining the grok and the [ruby filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-ruby.html) plugin, there it should be easy to split the message and create an array.

You might also find the Split filter useful for this: [https://www.elastic.co/guide/en/logstash/current/plugins-filters-split.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-split.html)

Best,  
Matthias
