vmstat - iostat - nfsstat

[Tom Brown <tom@xxxxxxxx>]

Hi

I urgently need to gather iostat, vmstat and nfsstat data on about 20 
boxes and log the results running over about a 24hr period. A shared 
filesystem is available to them all to record the data -

Does anyone know how i can do that as using things like vmstat and 
iostat etc i am struggling to script the output into a file.

Any ideas?
