Apache Stratos - The Open Source PaaS Framework

Recently, WSO2 proposed the "Apache Stratos" as an incubating project at the Apache Software Foundation. The vote for Stratos proposal started about a week ago.

We are really excited to hear the news that voting has passed less than 20 hours ago and Apache Stratos project is now officially in the incubator.

Apache Stratos will be a polyglot PaaS framework and it will be possible to run on any IaaS supported by jclouds. Interestingly, the jclouds is also currently an Apache incubating project.

The proposed Apache Stratos committer list includes developers from WSO2, Cisco, SUSE, Citrix, NASA Jet Propulsion Lab (JPL), Sungard and Engine Yard. I'm really happy that I'm also in the initial committer list!! :)

We recently released the Stratos Foundation 2.0 GA, which will be the last release of "Stratos" from WSO2.

The Stratos 2.0 GA release is also featured in many technology web sites such as InfoQ, JAXenter, BusinessWire, Kavis Technology etc.

Following diagram shows the Apache Stratos Architecture and you can find more details at WSO2 Wiki docs for now.


Everyone is welcome to join the Apache Stratos community and help to make it The Best 100% Open Source PaaS framework! :)

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 r...

Java Flight Recorder Continuous Recordings

When we are trying to find performance issues, it is sometimes necessary to do continuous recordings with Java Flight Recorder. Usually we debug issues in an environment similar to a production setup. That means we don't have a desktop environment and we cannot use Java Mission Control for flight recording. That also means we need to record & get dumps using command line in servers. We can of course use remote connection methods, but it's more easier to get recordings from the server. With continuous recordings, we need to figure out how to get dumps. There are few options. Get a dump when the Java application exits. For this, we need to use dumponexit and dumponexitpath options. Get a dump manually from JFR.dump diagnostic command via " jcmd " Note: The "jcmd" command is in $JAVA_HOME/bin. If you use the  Oracle Java Installation script for Ubuntu , you can directly use "jcmd" without including  $JAVA_HOME/bin in $PATH. Enabl...
