What we're about

All things Java / JVM in Vienna, Austria.

We try to meet once a month (except for summer holidays July, August) to discuss various Java related topics, including frameworks, best practices.

The meetup is aimed at beginners, intermediates and professionals as well.

Most of our meetings will be held at the University of Technology Vienna in the heart of the city center.

During the corona pandemic, we abstain from doing online meetups with talks that are already wildely available on the internet/youtube. We only make exceptions for content that is unique or from a member of our community who wishes to share it. If you are a "Developer Relations" person, this most likely means that your talks don't fit our profile during this non-onsite phase.

If you have something to share that is not already widely available, please reach out to one of the organizers.

Logging Considered Harmful? & OpenTelemetry for Java

Logging considered harmful?
One thing that enterprise Java applications have in common, regardless of their framework, is that they produce logs — allegedly human-readable lines of strings that aim to help us to debug, trace, or otherwise inspect what’s going on. The question is, how useful are these logs and do they help us solve problems that actually happen, and whether there are better alternatives for the average developer.

OpenTelemetry for Java (Philipp Krenn, EN)
OpenTelemetry is the hot new standard for getting telemetry data from your Java applications (and others). This talk covers three areas:

  • Standards: OpenTracing, W3C Trace-Context, and OpenTelemetry
  • Signals: Both what (traces, metrics, logs) and how (instrumentation, OTLP)
  • Demo: Making it work and where the boundary is between OpenTelemetry and vendors

Philipp lives to demo interesting technology. Having worked as a web, infrastructure, and database engineer for over ten years, Philipp is now a developer advocate and EMEA team lead at Elastic — the company behind the Elastic Stack consisting of Elasticsearch, Kibana, Beats, and Logstash. Based in Vienna, Austria, he is constantly traveling Europe and beyond to speak and discuss open source software, search, databases, infrastructure, and security.
