DSTAT an excellent tool which combines the overall stats of vmstat, iostat, netstat and ifstat. Dstat allows us to view all of the system resources in the real-time including the network bandwidth, network I/O , IRQ etc which helps the administrator to get an clear picture of what is going on in their server. It also reduces the headache of opening a separate shell/terminal to view the stats during bench tests.
