you can use `POM_login: "%{USER:user}" %{WORD:group} / %{WORD:role}`

for a more complete and flexible expression, you can use [https://grokdebug.herokuapp.com/](https://grokdebug.herokuapp.com/)

put your example line in the text box above, and gradually build the expression below, seeing what matches
