I have multiline pattern as below.

```
multiline.pattern: ^\[0-9]{4}-[A-Za-z]{3}-[0-9]{2}
multiline.negate: true
multiline.match: after

```

My logs look like below.

```
2018-Apr-02 00:10:46 AM [http-nio-8888-exec-3] INFO com.example.controller.SampleController - got request for hello
2018-Apr-02 00:10:52 AM [http-nio-8888-exec-1] INFO com.example.controller.SampleController - got request for hello
2018-Apr-02 00:13:10 AM [http-nio-8888-exec-9] INFO com.example.controller.SampleController - got request for hello
2018-Apr-02 00:13:38 AM [http-nio-8888-exec-7] ERROR com.example.controller.SampleController - exception
java.lang.NullPointerException: null
    at com.example.controller.SampleController.exception(SampleController.java:32) [classes!/:?]

    at java.lang.reflect.Method.invoke(Method.java:498) ~[?:1.8.0_161]

```

All the non-exception logs get combined and i see 1 entry on kibana.

The multiple exception messages also get combined and i see 1 entry on kibana.

I am not sure what i am missing. I dont have any include or exclude configuration. I am not using logstash.

I haven't tested your configuration, but when defining regexes, use single quotes.

The pattern config should be more like this:

```auto
multiline.pattern: '^[0-9]{4}-[A-Za-z]{3}-[0-9]{2}'

```

Btw. why did you put a `\` before the first `[` ?
