Why you should attend WSO2Con Asia 2014

WSO2Con Asia 2014, a must attend conference for anyone interested in WSO2 products, is just around the corner.

The WSO2Con Asia 2014 is scheduled from March 24 to March 26 with two conference days and one pre-conference tutorial day. Have a look at WSO2Con Asia 2014 Agenda for all interesting talks and tutorials WSO2 has to offer.

The conference will be held at Waters Edge, a popular venue in Sri Jayawardenapura Kotte, Sri Lanka.

Here are few reasons I can think of as to why you should attend the WSO2Con.


  • WSO2 is the only company to have a complete set of open source middleware products built from scratch and WSO2Con is a good opportunity for you to learn how we make world-class products.
  • Pre-conference tutorials will help you to get an understanding of how our stuff works. So, don't worry if you do not have much idea about the WSO2 products.
  • See what WSO2 has to offer with WSO2 Mobile subsidiary.
  • Meet the experts.
  • Networking opportunities.
  • Discover how WSO2 software can impact your daily life.
  • Be inspired. I'm sure you will be able to find many reasons (just as I did from previous conferences)
  • Our long term target is to be the #1 middleware company in the world. This conference is a milestone in that long journey. So, be part of the history! :)

There is a 25% discount for early registrations. Make sure you grab the opportunity while it lasts.

Have fun at the WSO2Con!
Location: Colombo, Sri Lanka

Specifying a custom Event Settings file for Java Flight Recorder

Image
When you are using Java Flight Recorder (JFR), the JFR will use an event settings file to check which event types to record. By default in JFR, there are two settings, "default" and "profile". The default setting is recommended for Continuous Recordings as it has very low overhead (typically less than 1% overhead). The profile setting has more events and useful when profiling the application. As mentioned in my previous blog post regarding  Java Flight Recorder Continuous Recordings , we use following arguments to do a Continuous Recording. -XX:+UnlockCommercialFeatures -XX:+FlightRecorder -XX:FlightRecorderOptions=defaultrecording=true,disk=true,repository=./tmp,dumponexit=true,dumponexitpath=./ Note: According to the Oracle documentation on " java " command, we should be able to specify "settings" parameter to the -XX:FlightRecorderOptions. However, the settings parameter has no effect when used with the -XX:FlightRecorderOptions and

Flame Graphs with Java Flight Recordings

Flame Graphs Brendon D. Gregg , who is a computer performance analyst , has created  Flame Graphs to visualize stack traces in an interactive way. You must watch his talk at USENIX/LISA13 , titled Blazing Performance with Flame Graphs , which explains Flame Graphs in detail. There can be different types of flame graphs and I'm focusing on  CPU Flame Graphs  with Java in this blog post. Please look at the Flame Graphs Description  to understand the Flame Graph visualization. CPU Flame Graphs and Java Stack Traces As  Brendon  mentioned in his talk, understanding why CPUs are busy is very important when analyzing performance.  CPU Flame Graphs  is a good way to identify hot methods from sampled stack traces. In order to generate CPU Flame Graphs for Java Stack Traces , we need a way to get sample stack traces. Brendon has given examples to use jstack  and Google's lightweight-java-profiler . Please refer to his perl program on generating  CPU Flame G

Java CPU Flame Graphs

Update (September 14, 2015): Java 8 Update 60 was released on August 18, 2015. There are some recent changes to "perf-map-agent". There is no longer a script named "perf-java" and you should use "bin/create-java-perf-map.sh " Brendan Gregg shared an exciting news in his Monitorama talk: The " JDK-8068945 " is fixed in Java 8 Update 60 Build 19 ! Without this fix, it was not possible to see full stack in Java with Linux perf_events and standard JDK (without any patches). For more information, see Brendan's Java CPU Flame Graphs page. The Problem with Java and Perf First of all, let's see what's the problem with using current latest Java and perf. For this example, I used the same program explained in my previous blog post regarding FlameGraphs . java org.wso2.example.JavaThreadCPUUsage.App Then I sampled on-CPU functions for Java program using perf. (See Brendan's Perf Examples ) sudo perf record -F 99 -g -
