MySQL Administrator :: 10.2 Connection Health

Connection Usage: Displays a percentage of the maximum number of simultaneous clients allowed (threads connected / max_connections). If this value gets close to 100%, it could indicate that you should increase the value of max_connections, which you can do in the Startup Variables section. The maximum number of connections since MySQL Administrator was loaded is also shown. For more information on server connections, see the SHOW VARIABLES and Too many connections Error sections of the reference manual.

Traffic: This is a representation of the bytes_sent status variable. This does not represent total bytes sent since server startup, but instead represents the current number of bytes sent (the bytes_sent variable is a cumulative total). The initial maximum value of the graph is 102400, this maximum value will be automatically increased as needed.

Number of SQL Queries: This is a representation os the com_select status variable. This does not represent total queries since server startup, but instead represents the current number of queries (the com_select variable is a cumulative total). The initial maximum value of the graph is 10, this maximum value will be automatically increased as needed.
