In any operating system, it is possible for an internet user to monitor the bandwidth usage. This is useful to keep track of internet usage in case you have a maximum bandwidth cap or download limit. To begin you need to install a software called SurplusMeter on your OS X. SurplusMeter can be downloaded from here.
It would be handy to have some method to know the Internet usage and the bandwidth availability, since most of the Internet providers limit the user with a cap transfer.
Netstat Live is one such application which gives the user, the available bandwidth, the throughput of download and upload data, irrespective of using either a modem, cable modem, DSL, or even local network.
