Hello,

Is it possible to define a global patterns\_dir for all cases in filter or it must be defined in each grok section.

Se below:

```
   if ("xxx" in [path]) {
      grok {
        **patterns_dir => ["/usr/share/logstash/patterns"]**
        match => { "message" => "^%{TIMESTAMP_ISO8601:timestamp}\;%{LOGLEVEL:loglevel}(.*);%{OPTIONALUSERNAME:user};%{TNR:tnr};%{INTEGRATION:integration};%{THREAD:thread};%{WORD:classname};%{GREEDYDATA:logmessage}$" }
        add_field => ["logtype", "xxx"]
      }
    }
    if ("yyy" in [path]) {
      grok {
        **patterns_dir => ["/usr/share/logstash/patterns"]**
        match => { "message" => "^%{TIMESTAMP_ISO8601:timestamp}\;%{LOGLEVEL:loglevel}(.*);%{OPTIONALUSERNAME:user};%{TNR:tnr};%{INTEGRATION:integration};%{THREAD:thread};%{WORD:classname};%{GREEDYDATA:logmessage}$" }
        add_field => ["logtype", "yyy"]
      }
    }
```

You'll have to define it everywhere.

In this case I don't understand why you have two grok filters.
