The Amazing Chronon 3

Posted by Prashant Deva on November 1, 2012

Its been a long time coming, but Chronon 3 is finally here!

In the next few posts, we will dive deep into what took us so long and all the technical magic that makes Chronon 3 tick. For now lets see what Chronon 3 brings us:

Features

  • Enormous performance upgrade
  • C3-memusage

The number one issues of Chronon users has been running into OutOfMemoryErrors and all of Chronon 3 is dedicated to eradicating that. The all new, rewritten from scratch Recorder is built to conserve memory. It uses off heap memory as much as possible and even then limits the amount of total data collected by the Recorder to be many times lower than that of previous versions. This graph gives you an idea of the improvement.

  • 5x faster unpacking

The Unpacker is much faster too! Apart from consuming much, much less resources, it also runs 5x faster!

  • Per Thread Time

With Chronon 3, we are introducing Per Thread Time, which gives each thread its own timeline, facilitating in must easier and faster debugging. Now the timeline view shows you the time and progess of the current thread instead of the whole system, giving you much more focused data. This is carried on in other views too, like the Stack view shows the current thread only instead of cluttering the view with all the threads in the system. The result of this is much more focused data and it also allows us to make the recorder more concurrent and faster.

  • On Demand Split

In case you missed it, a few months back we also introduced On Demand Split in the Recording Server, allowing you to split recordings anytime, without having to wait for a split interval.

  • Support for JBoss

Previously, Jboss 7 was having issues with Chronon due to OSGI classloader issues. With Chronon 3, this should be solved and you should be able to fully record your JBoss apps.

Future Updates

Now that we are done with this huge release, we will be doing much, much faster releases to keep bringing you new features. Due to time constraints for this release, we have decided not to include the ‘Recorded Console’ view. We think with Post Execution Logging you can achieve the same goal without cluttering your code with println() statements. However, if there is demand for it, we will bring the view back in the next update.
