Description:

Dstat is a versatile replacement for vmstat, iostat, netstat, nfsstat
and ifstat. Dstat overcomes some of their limitations and adds some
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, you
can eg. compare disk usage in combination with interrupts from your
IDE controller, or compare the network bandwidth numbers directly with
the disk throughput (in the same interval).
