Hello,
I am trying to parse a log file in multiline format and each new linestarts with the date :
28-Sep-2020 18:26:19.982
I tried to configure the config as below :
```
filebeat.inputs:
- type: log
tags: ["PROD_CATALINAOUT"]
paths:
- /catalina.out
multiline.pattern: '^\%{MONTHDAY}'
multiline.negate: true
multiline.match: after
```
However, it does not seem to be working...I found that the entire log file has been written as a single entry...How do I fix this?

You should move this to the filebeat forum, it is not a logstash question.
