Default dstat choices
Have been you to make use of the dstat command with no choices, the output would come with much more particulars than you would possibly count on and would look extra like what you see under.

Discover that this output contains stats utilization, disk learn and write, community exercise, paging and system stats. The output from utilizing dstat with out choices is identical as utilizing dstat with the “cdngy” choices (dstat -cdngy).
To get eight traces of this info in 2-second intervals, add the numeric arguments as proven on this command:
$ dstat 2 8 You didn't choose any stats, utilizing -cdngy by default. ----total-usage---- -dsk/total- -net/total- ---paging-- ---system-- usr sys idl wai stl| learn writ| recv ship| in out | int csw 0 0 99 0 0| 0 0 | 298B 541B| 0 0 | 123 197 0 0 99 0 0| 0 0 | 54B 346B| 0 0 | 64 114 0 0 99 0 0| 0 0 | 87B 515B| 0 0 | 66 117 0 0 99 0 0| 0 0 | 54B 346B| 0 0 | 78 125 1 0 100 0 0| 0 0 | 277B 346B| 0 0 | 62 113 1 1 99 0 0| 0 0 |3893B 411B| 0 0 | 110 144 5 0 85 10 0| 0 128k| 54B 346B| 0 0 | 213 152 1 0 98 0 0| 0 180k| 54B 354B| 0 0 | 92 149

Utilizing different choices
The cdngy arguments (as you may inform from the output above) signify cpu, disk, community, paging and system stats. To show used and free reminiscence with dstat, use a command like this:
$ dstat -s ---total--- used free 768k 3783M 768k 3783M 768k 3783M 768k 3783M 768k 3783M 768k 3783M
To show prime CPU usages, you would use a command like this:
