   .. tab-item:: EXAMPLE

      The following command displays the current remote procedure call metrics for the :term:`alias` ``myminio`` deployment.

      .. code-block:: shell
         :class: copyable

         mc support top rpc myminio/

      The output returns information such as the server, number of connections, length of ping, time since last ping (``pong``), reconnections, string in, string out, messages in, and messages out.

      The output resembles

      .. code-block:: bash

         λ mc support top rpc myminio
