    Description

      When a disk name has a "/", the disk stat name gets mistakenly parsed to include everything after the first "/". This causes the prometheus scrape to fail.

      The expected behaviour would be to report for example the "queue" stat for disk "abc/xyz" as "sys_disk_queue" with label "disk" equal to "abc/xyz".

      Instead we see the same reported as "sys_disk_xyz/queue" with label "disk" equal to "abc".
