      Since this occurred on a version of mongostat prior to 3.0, I suspect that this has gone away. If someone has a more recent occurrence of this, then feel free to reopen.

      Mongostat won't work on a replicated sharded cluster when one of the shards is misbehaving. Note this only happens with the --discover flag. Without that flag, it reports correctly.
