We have a proprietry system, which runs on Tru64 Unix. It is a terminal based system. We are able to use the login 'vmstat' to the system which brings up a vmstat-like view. However, the information displayed is slightly different from the standard vmstat.

The 'r' for processes is part of the standard vmstat layout, but not 'w' or 'u'. I cannot find any references to this kind of vmstat layout on google. According to linuxcommand.org I should get the layout:

r  b   swpd   free   buff  cache   si  so    bi    bo   in    cs us sy id wa

instead of:

r   w   u  act free wire fault  cow zero react  pin pout  in   sy  cs us sy id

Is anybody able to shed any light as to why mine is different? Or at least what each of the fields mean?

Thanks, after a lot of digging I found the documentation for Tru64 vmstat on HP's site. Google seemed to fail me on this occasion.

Yours is different because you're running Tru64, and not linux.

(most 'standard' unix programs will differ slightly in their options and output depending on their source - gnu/bsd/sun/etc.)
