How to treat JSON as a string

[BKG]

Hi,

What would be the best way to handle JSON which appears in amongst my normal logs. We don't require parsing of individual fields, just need it to be displayed as a string as this JSON appears very rarely.

As you can see in the message field, it's failing when it's hitting the first JSON element...... or is it a quote escape issue?

I have other multi-line logs working fine.

Thanks!

How are you combining the multiple lines into a single event?

Thanks for the reply @Badger

I figured it out.. this is a new type of multi-line log for me.

This is my multiline setup now, which now combines logs that start with " ", "}" or ")"

multiline.pattern: "^( |}|\))"
multiline.negate: false
multiline.match: after

I think you are missing something in your Grok pattern:

Working:

Note the (?m) at the start telling RegEx to do multiline matching

I had no idea you could do this. It actually seems like a much more resilient way of handling it rather than using multiline.pattern.

Thanks again!
