dstat – Versatile tool for generating system resource statistics
Sometimes sysadmins have to debug a computer running with (too) high load. I usually used free(1), cat /proc/interrupts, vmstat(8) [-s, -m,…] and top(1) to debug such situations. Today I stumbled upon ‘dstat’. It produces some important stats in realtime with (IMO) readable output. Check it out! And please let me know if you know of any other tools like this one. :-)
