djigger v1.4.2 is available for download !

We are excited to announce the first public release of djigger (v1.4.1), our production-ready open source monitoring solution for java !

This is the first step as part of the denkbar initiative, and our goal here is simply to make available to the community what started out as a small thread dump analyzer and grew into a more mature production-ready APM solution.

I want to start off by thanking all of the people who made this possible, clients who trusted us and let us implement and test out our features against a variety of complex applications, but also colleagues and friends, who tried out the tool and helped us with their valuable feedback.

At this point there's still a lot of potential to unleash and great functionality to be built, but we're very confident that what we're releasing today can already make a big difference in the way many people and companies analyze performance problems.

We've really juiced the sampling approach like no one has ever done before (at least that we know of), and we're still working on milking that information cow some more. There's just so much you can do with just sampling, you or at least most people would be very surprised.

On top of our sampler, we've built a series of filtering, aggregation and visualization functions that allow you to inspect and understand your code in a very unique way. Once you think you're in a situation where you can't avoid instrumentation (which is highly intrusive) anymore, then you can use our process attach and/or agent mode functionality to start instrumenting methods and get the answers you need. We're now actively extending agent style and instrumentation functionality and we're planing on introducing a lot of new features very soon, such as distributed transaction tracing, getter injection and primitive types capturing.

Also, we intend to provide active support to the best of our ability (and availability) and we'll try to build as much momentum as we can in order to give djigger a chance to fly on its own. We hope the community responds, and we'd like to already thank in advance the people who'll try out djigger.

On that note, we've put a lot of effort in the last few days to package the tool in as pleasant a way as we could (which isn't necessarily easy considering the numerous supported connectors, JVM vendors, JDK versions, OS-specific start scripts, etc), and we hope we've made life easy for you as a user.

That said, we'll definitely appreciate any feedback you can give us, especially if you're stuck early in your attempt at using the tool. In a few days, we'll put up a form on the Contact page at denkbar.io, so you can get in touch with us directly, but for now, feel free to report any issue you like on our github repository.

We'll do our best to help you get going and fix any bugs as quickly as we can!

Signing off.
