Hi @ivana27,

if the code you need to display is only the code between square parenthesis, you could use a regex like this:

| rex "PosService\s+AddInfo:\[(?<addinfo>\d+)"

as you can see at https://regex101.com/r/dtpR2J/1

If instead you need to display all the message until the end of the row, you have to use the following regex:

| rex "PosService\s+AddInfo:(?<addinfo>.+)"

 as you can see at https://regex101.com/r/dtpR2J/2

Ciao.

I hope @gcusello  answer suffice.

If you want to extract after ":" (and considering whatever before ":") you can also use

":\[(?<addinfo>\d+)]"
OR
":(?<addinfo>.+)"
