To use the Replication Status section you must be connected to the server that acts as the master in your replication scheme. Your MySQL servers must be version 4 or higher to use this feature.
      For a slave server to show in the Replication
      Status screen, it must register itself with the master
      server. To have a slave server register itself with the master,
      set the report-host option in your server
      configuration (my.cnf/my.ini) file. See
      Replication and Binary Logging Options and Variables.
    
You can also set the value in the Replication tab of the Startup Variables section of MySQL Administrator.
