JavaOne 2007 Screenshots

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.xml
• java_thread_method_calls.xml
• monitor_wait_times.xml

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.

Monitor Wait Times  

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