mongostat --discover does not alias localhost to the target hostname

    • Type: Icon: Bug Bug
    • Resolution: Done
    • Priority: Icon: Major - P3 Major - P3
    • 3.2.8, 3.3.11
    • Affects Version/s: 3.0.0-rc6
    • Component/s: mongostat
    • None
    • v3.2

      This one I know to be an existing issue with mongostat 2.6 and earlier.

      To reproduce:
      1.) Start up a vanilla 3 node set on say ports 2400, 2401, 2402.
      2.) $ mongostat --port 2400 --discover 5

      Note the repeated entries for the mongod on 2400 – one for localhost and another for the hostname.

      A workaround does exist of specifying the correct hostname instead of letting mongostat default to localhost, e.g.,
      $ mongostat --host John-Morales-MacBook-Pro.local --port 2400 --discover 5
