If you use a REST Appender you can set this meta data at the source.
Have you looked at the example configs ?
I see...thanks again.
Yes. This is explained in the README ( https://github.com/damiendallimore/SplunkJavaLogging/blob/master/README.md ) and shown in the example config in the the link I posted in my previous reply.
Thanks for your answer Damien.
I'm just looking around...are there rest endpoints for sending data to a forwarder? I had been using a tcp appender sending data to a forwarder on the same host as my app.
