Is there a way to subscribe to the information output to the screen by Gmapping? It prints out a lot more information that it allows subscriptions to or services for. I want to be able to get that information without modifying the Gmapping code.
IIRC gmapping does not use ROS_... output, so it is not possible by a ROS way. You could still open the output in a pipe or something like that.

In which datum specifically are you interested?
Specifically, I'm interested in the Average Scan Matching Score and the Scan Matching Failed alert.
I'm unfamiliar with how to open the output in a pipe....
EDIT: After reading about ROS launch output, (either output to "screen" or "log") piping does seem to be the ONLY way. Thanks for the advice
@dornhege was right. I was able to pipe it into a simple publisher I wrote. Thanks. I am now opening up a new Question to see if I can add pipes to roslaunch xml files.
