thrbar : perfbar for threads

thrbar 1.0, for Solaris 9 and higher

Originally there was "perfbar".

"perfbar" gives a near realtime view of CPU utilization states.
In perfbar red=kernel, green=user, yellow=wait on IO, blue=idle, and white is indeterminate.

It is common for an early indication of a performance issue to be obvious in perfbar.

I realized that it would be wonderful to have a perfbar for threads. So I borrowed the gui for perfbar and modified it to use procfs to access thread CPU utilization states and display them ala perfbar.

In thrbar
white=indeterminate
green=user
red=kernel
yellow=latency (wait for cpu)
orange=wait for Lock
blue-green=wait for PageFault
blue=SLEEP

I have prebuilt the binaries.
Sorry, I can not distribute the source.
cp thrbar.i386_32 or thrbar.i386_64 or thrbar.sparc_32 or thrbar_64 to thrbar and you are ready.
