 From  "man mdadm"  (if you know where to look)

       Follow or Monitor
              Monitor  one  or  more  md devices and act on any state changes.
              This is only meaningful for raid1, 4, 5, 6 or  multipath  arrays
              as  only  these  have  interesting state.  raid0 or linear never
              have missing, spare, or failed drives, so there  is  nothing  to
              monitor.

You are presumably trying to monitor a raid0 (which isn't meaningful)
and mdadm is telling you (in its own idiosyncratic way) that it isn't
going to monitor it.
