Lerna output json

Hi,

I'm trying to setup my logging, for my application, but this is running via lerna.
Which means it outputs first the package name and then the log

Which makes the output look like this:

info cli using local version of lerna
lerna notice cli v4.0.0

I was wondering on how I should setup filebeat to work with this?

Hi!

Can you redirect this output to a file maybe? Then you can set filebeat to collect logs from this file.

UPDATE: found a way to omit the @badvlasim/server so now the logs are:

I don't see the error anymore, but I don't see any logs appearing
