The df check is now excluding all filesystems found below /var/lib/docker, which is the default location for the docker container local storage.
Depending on the used storage engine docker creates overlay filesystems and mounts below this hierarchy for the started containers.
The filesystems are not interesting for our monitoring. They will be monitored from the container context.
