2. • The dstat monitoring tool

Dstat is a versatile replacement for vmstat, iostat, mpstat, netstat and ifstat. Dstat overcomes some of their limitations and while also adding extra features, more counters and flexibility. Dstat is handy for monitoring systems during performance tuning tests, benchmarks or troubleshooting.

Dstat allows you to view all of your system resources instantly. For example you can compare disk usage in combination with interrupts from your IDE controller, or compare network bandwidth directly with disk throughput.

ifstat gathers these statistics from the kernel internal counters, which is highly operating system dependent.

5. • The vnstat network traffic monitor

vnStat (view network statistics) is a network utility for the Linux operating system. It uses a command line interface. vnStat command is a console-based network traffic monitor. It keeps a log of hourly, daily and monthly network traffic for the selected interface(s) but is not a packet sniffer. The traffic information is analyzed from the proc filesystem. That way vnStat can be used even without root permissions.
