I finally got some time to start testing JsonTemplateLayout against the logging in the cloud documentation. The first problem I ran into is that additional fields don’t work. I don’t see any configurations that have them and the Builder doesn’t have annotations on the key and value fields so I suspect it just doesn’t work. Why didn’t you just enhance KeyValuePair to add the type attribute?
After I corrected the EventTemplateAdditionalField plugin I still can’t get stack traces the way I want them. I thought you said you added the ability to format the message using a pattern, but I don’t see that in the documentation or in MessageResolver. Was that not included? As I said, I require the stack trace to print in the message field in Kibana, not just be a key in the additional data. Ralph
