In my cluster on Atlas, have a many connections in secondary nodes.
How to list this connections?

When execute this command, list the current connections in primary node.

  (accumulator, connection) => {
    ipaddress = connection.client ? connection.client.split(":")[0] : "unknown";
    accumulator[ipaddress] = (accumulator[ipaddress] || 0) + 1;
    accumulator["TOTAL_CONNECTION_COUNT"]++;
    return accumulator;
  },
  { TOTAL_CONNECTION_COUNT: 0 }
)


{

}

But, I have 700 connection in replicaSet.Connections in Atlas Server
