Hello,

I have several log files that share the same id.  
I want to extract the message part out of them and write these in a new document so you can see the "progress" in one document.  
I tried the aggregate filter and many different more options but none of them brought me to the result I want.  
Do you have any suggestion what a possible solution could be?  
Thanks in advance!
