Two questions

[asasas234]

I have two questions, one is that one of the fields I configured in message_format is an array type, when I output it to the browser, I found that it has been spliced with commas, I want to replace the commas with \n, how do I configure it?

Another problem is that I want some multiple logs to be stitched into one line, for example, when log.flags = multiline appears in successive log messages in ES, I want them to be stitched into one line
