Is there any way to obtain server (cluster wide) stats such as:
Bytes received - bytes received from all clients
Bytes send - bytes sent to all clients
Connections - number of connection attempts
Aborted_connects - The number of failed attempts to connect to the server
like in MySQL (http://dev.mysql.com/doc/refman/5.6/en/server-status-variables.html)
with SHOW GLOBAL STATUS query ? I can't find them.
