Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Discover the key concepts of OpenTelemetry Java through practical installation exercises for the SDK and automatic agent, configure your first manual spans in a simple Spring Boot application, test export to a local console, analyze generated traces in real-time, and produce your first performance reports to identify basic bottlenecks in a professional context.
Dive into distributed tracing with OpenTelemetry Java, implement context propagation via W3C headers in Java microservices, instrument HTTP and gRPC calls, simulate complex trace chains in a Docker environment, visualize dependencies with Jaeger, and optimize performance by debugging real latencies for scalable enterprise applications.
Master the collection of custom metrics with OpenTelemetry Java, integrate counters, histograms, and gauges into Spring Boot code, configure export to Prometheus, enrich logs with trace attributes, test high-load scenarios, analyze trends in real-time, and generate dashboards to monitor critical resources in professional production.
Integrate OpenTelemetry Java with real stacks like Spring Boot and Kafka, instrument JPA/Hibernate interactions to trace SQL queries, configure propagation in asynchronous streams, deploy on Kubernetes with sidecar agents, simulate outages to validate resilience, and produce observability deliverables ready for enterprise operations in a certifying context.
Optimize your OpenTelemetry Java setups with best practices for adaptive sampling and batching, deploy complete pipelines to Elastic or Grafana, configure alerts based on traces and metrics, review real error cases from DevOps teams, consolidate skills through a final capstone project, and prepare for production adoption for sustainable professional observability.
The Training OpenTelemetry Java - Mastering Distributed Observability program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.
The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
