Here are 2 screenshots of older dstat versions in action. 

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.

If you've found a bug, please check the TODO file for known problems and send me updates if you have more information to provide. 

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. or grab the latest 0.7.2 tarball at: http://dag.wieers.com/home-made/dstat/dstat-0.7.2.tar.bz2
