Thanks - prustat works great once I point it at Sun's perl (I was using a newer install) I'm going to record some snapshots when the contention is happening...
What if I wanted to quantify the latency (wait times) due to DNS lookups (I suspect I could benefit from a local caching install - but I want a "before") picture so I can show how much better it is using a local DNS cache...

It's probably already under /usr/perl5/5.8.4/lib - it's a vendor (Sun) supplied package. prustat was written as a demo tool - it might be useful, but it will probably fail due to a kernel change. I wrote it when I was a customer to make a point to Sun that this is the sort of tool that customers would like. It turns out that supporting this tool for customers would require stable network providers for DTrace, a project that is still in progress. I never put prustat into the DTraceToolkit because it wasn't stable enough, despite it providing key resource utilisations by process (which is wonderful, and made possible by DTrace). If anyone hasn't seen it, it looks like this: # prustat -ct 20 5 PID %CPU %Mem %Disk %Net COMM 22301 78.84 3.16 0.00 0.00 setiathome 22635 4.09 0.20 69.11 0.00 tar 440 2.76 45.39 0.00 0.00 Xsun 2618 0.31 14.34 0.00 0.00 mozilla-bin 22640 3.87 1.49 0.12 0.00 dtrace 582 2.04 2.16 0.00 0.00 gnome-terminal 576 0.02 2.80 0.00 0.00 nautilus 2299 0.33 1.99 0.00 0.00 acroread 22641 0.00 0.00 1.84 0.00 upsmonitor 578 0.37 1.46 0.00 0.00 gnome-panel 574 0.41 1.31 0.00 0.00 metacity 6504 0.00 1.23 0.00 0.00 nautilus-throbb 593 0.04 1.05 0.00 0.00 mixer_applet2 556 0.00 1.05 0.00 0.00 gconfd-2 549 0.00 0.94 0.00 0.00 gnome-session 6510 0.00 0.93 0.00 0.00 nautilus-text-v 591 0.02 0.83 0.00 0.00 galf-server 21551 0.00 0.56 0.00 0.00 dtterm 4789 0.10 0.45 0.00 0.00 vncviewer 553 0.00 0.43 0.00 0.00 gnome-volcheck the screen updates like William LeFebvre's top. Let me stress again - prustat was written to demonstrate an idea, but is currently unstable as a tool.
