getting this error when trying to start logstash

[2017-05-11T12:35:56,772][ERROR][logstash.filters.grok] Unknown setting 'pattern\_definitions' for grok  
[2017-05-11T12:35:56,795][ERROR][logstash.agent] Cannot create pipeline {:reason=\>"Something is wrong with your configuration."}

using the example from

[https://www.elastic.co/guide/en/logstash/5.4/logstash-config-for-filebeat-modules.html#parsing-system](https://www.elastic.co/guide/en/logstash/5.4/logstash-config-for-filebeat-modules.html#parsing-system)

I think its this that is causing the problem

pattern\_definitions =\> {  
"GREEDYMULTILINE"=\> "(.|\n)\*"  
}

any idea where I can get the pattern for GREEDYMULTILINE, I seem to be missing it on Debian

The `pattern_definitions` grok option is only available in recent versions of the grok filter. Try updating it. Otherwise you can put the pattern in a pattern file.
