GrayLog2 Email Alert Callback variables

Question

By default Graylog2 seems to use these variables in it's email alert callbacks:

Date: ${check_result.triggeredAt} 
Stream ID: ${stream.id} 
Stream title: ${stream.title} 
Stream URL: ${stream_url} 

What are the others that are available?

Is {source} and {path} available? The documentation is non-existent regarding alert callbacks.

Answer 1

Try to use

message.fields.yourfield (e.g. message.fields.path)
