Then your going to want to split the line
since your format is pretty well formated it should be easy.
I am thinking of something like the following
Use the kv plugin to just split everything in to different fields, don't worry about the actual data you want, parse it all and then you can go from there.
[https://www.elastic.co/guide/en/logstash/current/plugins-filters-kv.html#plugins-filters-kv-value\_split](https://www.elastic.co/guide/en/logstash/current/plugins-filters-kv.html#plugins-filters-kv-value_split)
```auto
filter {
kv {
field_split => "\]\["
value_split => "\ "
}
}
```
