-C 0,3,total include cpu0, cpu3 and total
-d, --disk enable disk stats
-D total,hda include hda and total
-g, --page enable page stats
-i, --int enable interrupt stats
-I 5,eth2 include int5 and interrupt used by eth2
-l, --load enable load stats
-m, --mem enable memory stats
-n, --net enable network stats
-N eth1,total include eth1 and total
-p, --proc enable process stats
-r, --io enable io stats (I/O requests completed)
-s, --swap enable swap stats
-S swap1,total include swap1 and total
-t, --time enable time/date output
-T, --epoch enable time counter (seconds since epoch)
-y, --sys enable system stats
--aio enable aio stats
--fs, --filesystem enable fs stats
--ipc enable ipc stats
--lock enable lock stats
--raw enable raw stats
--socket enable socket stats
--tcp enable tcp stats
--udp enable udp stats
--unix enable unix stats
--vm enable vm stats
--plugin-name enable plugins by plugin name (see manual)
--list list all available plugins
-a, --all equals -cdngy (default)
-f, --full automatically expand -C, -D, -I, -N and -S lists
-v, --vmstat equals -pmgdsc -D total
--float force float values on screen
--integer force integer values on screen
--bw, --blackonwhite change colors for white background terminal
--nocolor disable colors (implies --noupdate)
--noheaders disable repetitive headers
--noupdate disable intermediate updates
--output file write CSV output to file
delay is the delay in seconds between each update (default: 1)
count is the number of updates to display before exiting (default: unlimited)

Dstat 0.4 on a Power5 system that is being stress tested.
Dsta 0.3 (first release) on 5 RHEL3 nodes in a cluster from a Windows terminal.
Please also copy&paste the output of the problem, with a description, the version of the kernel and if appropriate the involved /proc entries.
Dstat has a --debug option to profile plugins and show what plugins and /proc entries are affected. Dstat also shows some more information with the --version option that might be useful. The following packages (in order of appearance) are available.
- Red Hat Enterprise Linux / CentOS
- Fedora
- Gentoo
- OpenSUSE
- Debian
- Mandriva
- Alt Linux
- cAos
- Ubuntu Breezy
- Linspire
