Thanks for the fast answer.
A couple more questions:
gstat gives percentage values: what are these and how are they computed?
In the man page I can find no answer.
iostat is also expecially interesting, since it can run
non-interactively and I could poll it through cacti...
However this monitors only raw da devices. Is there a way to get
Finally this gives overall MB/s, which is very interesting, but I'd also
need to refer this to an end-of-scale value, in order to understand if
the disks are working to their fullest (and thus are the bottleneck).
Is this correct? Where could I desume such a value? (I remember there
was an utility... though I don't remember its name).
bye & Thanks
