(w)dstat

wdstat

In my .profile (on CentOS 5, just in case there were some changes in dstat) I have following alias to dstat (wdstat stands for Wawrzek's dstat):

alias wdstat="dstat -lcpymsgdn 5"

Where the options stands for:
  • -l  - UNIX load (1m   5m  15m) load average in 1, 5 and 15 minutes, respectively;
  • -c - cpu stats (usr sys idl wai hiq siq) percent of time spent in user and system space, idle, waiting on resource,  serving interrupts and softirqs (software interrupts);
  • -p - process stats (run blk new) number of running, blocked and newly created processes;
