If you ever need to open a support ticket with SUSE you usually need to send them your supportconfig report which includes a system summary, your configuration, and your current logs.This is also good information to gather if you are doing your own troubleshooting or setting up a device database like a CMDB.
This image does the same thing for any machine
docker run -it -v [where you want the saved logs]:/root -v /etc:/etc -v /var:/var jsevans/supportconfig
This image is built on Leap and should work on SLES 12, OpenSUSE Leap, and Tumbleweed machines.
You can try it on other images, but depending on where they keep their logs and configurations, your results may vary.
