how can i use rex to extract those numbers and leters that is next to enviroment= . There are many logs with those lines . That number represent a unice id for some device that hits some backend. I then need to do a table with every single device extracted in the last 15 days for example

thanks!

If it is always the last thing on the line,

rex "environment=(?<MyFieldName>\S+)$"

If it is not, drop the last dollar sign off and it'll ONLY grab up to the next space.
