Kibana Grok Debugger Multiple Custom Patterns

Hi Lukas.
Currently all I am trying to do is to put more than one custom grok pattern in the debugger. But for the purpose of resolving this issue I will provide you with a screenshot of what I have so far.


So as you can see above I have used a custom grok pattern to match the 'Host' section of the log. Below is what I would like to achieve, however I believe my syntax is incorrect in the 'Custom Grok Patterns' section.

cheers,

G
