@marius: already doing in some machines, there pidstat and iopp work well. But the real gem, iotop, doesn’t work because it requires Python 2.5 and it’s only present in lenny (no backport either)

@Vide: you can use the etchnhalf 2.6.24 kernel in etch. We are using it for some time now on all our etch machines. As another note iotop also depends on python2.5.

@aero: I mentioned about that also and have one other post describing pidstat. this is not available on older distros like debian etch by default and only in newer sysstat packages >= Sysstat 8.0.0.

In sysstat package.
pidstat command does it

$ pidstat -d
Linux 2.6.27-11-server (host) 03/09/09 _i686_

iotop is *really* sweet and definitely a must for every installation!
It’s a pity that all these tools only work with 2.6.20 or above kernels so they don’t work on a stock (old) Debian Etch.
But anyway we are all supposed to update our Etch in a couple of months anyway no?
Thanks for the tip anyway… I repeat myself: iotop is wicked cool!
