[[instances]]
  ## specify address via a url matching:

  ## All connection parameters are optional.

  ## Without the dbname parameter, the driver will default to a database

  ## connection with the server and doesn't restrict the databases we are trying
  ## to grab metrics for.

  ## measurement output. If not specified, a default one generated from
  ## the connection address is used.
