Server Monitoring using DSTAT

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.
