🕵️‍♂️ I have multiple grok filters but I point all of them to a single patterns\_dir like below. 🕵️‍♂️

```auto
  grok { patterns_dir => ["/usr/share/logstash/patterns"] }
  grok { patterns_dir => ["/usr/share/logstash/patterns"] }
```

If I move all my custom patterns into

```auto
/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-patterns-core-4.1.2/patterns/
```

then I don't have to declare any patterns\_dir.

**Can I define a custom patterns\_dir once in logstash that all groks will get?**  
I would rather keep my patterns separate from the core patterns\_dir but don't want to define the same location over and over again.
