disk utilization is over 200%
Hello,
I use Brendan''s sysperfstat script to see the overall system performance and
found the the disk utilization is over 100:
15:51:38 14.52 15.01 200.00 24.42 0.00 0.00 83.53 0.00
15:51:42 11.37 15.01 200.00 25.48 0.00 0.00 88.43 0.00

[DTrace] %CPU, %Mem, %Disk and %Net by PID
...ll reports every 10 seconds
prustat -ct 22 -s cpu 5 # 22 lines, sort by cpu, every 5 secs
prustat -ct 22 -s mem 5 # 22 lines, sort by mem, every 5 secs
prustat -ct 22 -s net 5 # 22 lines, sort by network, by disk, every 5 secs
...
My performance obsession also led me to write sysperfstat last
night/morning,
$ sysperfstat 1

Dtrace scripts for performance data gathering
I am looking for Dtrace scripts that can be used to
collect data during performance tests. I am especially
interested in IO but CPU, memory, threads, etc are needed
as well.
Thanks,

expected system load from DTrace scripts/probes
Does anyone out there have any thoughts on the type of load common
DTrace scripts would cause on a system if run 24x7? I know "common
DTrace scripts" and their underlining probe calls a vague statement. So
for the lack of a common and establish set of scripts in the OS, I''ll
use the most popular right for my question...the DTraceToolkit from
Brendan Gregg. Which by the
