I have some springboot logs that start like this:

2018-09-11 09:18:42.968 INFO 12036 ---

And I created a pattern in the filebeat.yml file to consider multiple line logs as part of the previous line like this:  
`
#=========================== Filebeat inputs =============================`

filebeat.inputs:

# Each - is an input. Most options can be set at the input level, so

# you can use different inputs for various configurations.

# Below are the input specific configurations.

- type: log

Hi @Nelson_Ferreira_Juni and welcome 🙂

I don't think the pattern you are using is a valid regular expression for filebeat. Filebeat uses golang regular expressions, that follow [RE2 syntax](https://github.com/google/re2/wiki/Syntax). You could start trying with a simple regular expression to match the year, then continue polishing it.
