My advice on debugging grok patterns can be found [here](https://discuss.elastic.co/t/help-needed-in-grok/213827/2).

In filebeat setting ignore\_older to zero means to include everything. In logstash, setting ignore\_older to zero means to _exclude_ everything more than zero seconds old, which usually excludes everything.
