You can use dissect to parse the first two elements, and a kv filter to parse the rest

```
dissect { mapping => { "message" => "%{[@metadata][ts]} %{+[@metadata][ts]} %{+[@metadata][ts]} %{ip} %{[@metadata][restOfLine]}" } }
kv { source => "[@metadata][restOfLine]" }
date { match => ["[@metadata][ts]", "MMM dd HH:mm:ss" ] }
```
