I am currently playing with some line breaking. But in order to test it I need to update my crcSalt, and restart Splunk. A little time consuming. Is there a faster way of doing this I am unaware of?
You can do it on the fly in the UI via the add data feature. It gets a little wonky at times and you have to start over at the sample data upload screen and upload again. Sometimes you have to close your browser and try again too.
You can use the http://<host>:8000/en-US/debug/refresh command.
