Not on this box. The problem with sar/vmstat/iostat is that they can't give detail about which process the activity belongs to, and netstat/lsof just give a snapshot of the state of the system - not what it's been doing recently. Ray suggested filemon but it's supplied as binaries compiled with gcc2 (and my boxes are gcc3 based).

The Sun boffins have come up with a package called dtrace which looks very funky for black-belt systems administration....but only on Solaris. I did find what looks like a good guide to performance tuning at: http://people.redhat.com/alikins/system_tuning.html I suspect there might be some useful info in the /proc filesystem somewhere (http://www.comptechdoc.org/os/linux/howlinuxworks/linux_hlproc.html) but I need to write something to seperate the wood from the trees.
