When i access my 3750 stacks through the web interface. In the dashboard - switch health, the stack bandwith & stack packet error, along with the port utilization is not measured.
To know the information about a specific port use the command "show switch stack-ports ".Regarding information about frames use the command "show switch stack-ring activity [detail]".To know the switch health command " show switch " would be helpful.For inforamtion about specific switch "show switch stack-member-number".Refer the following URL for more info
