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

filter {
  kv {
    field_split => "\]\["
    value_split => "\ "
  }
}
