Screenshots of Displays from Steven Reynolds' 2007 JavaOne Presentation
Steven Reynolds presented Chime at JavaOne this month, and he posted his presentation slides and display descriptions here. I downloaded the displays from his page, ran them on my desktop, and took a screenshot of each one:
Java Method Calls
Java Thread Method Calls
Steven helpfully pointed out in the Description (above) a way to find thread IDs:
prstat -p <JVM pid> -L or prstat -p <JVM pid> -mL
The first time I ran the display, I neglected to scroll down the Description pane and missed that tip, but I ended up finding thread IDs my own way with Chime:
/opt/OSOL0chime/bin/chime -n 'syscall:::entry / execname == "java" / { @syscalls[pid, tid] = count(); }'
For those unfamiliar with the Chime -n option, check out how to generate displays on the Command Line.

Thanks Steven, and nice job! I hope you'll be presenting Chime at JavaOne again next year.
