Why this program matters

  • Without expert OpenTelemetry Java, 75% of microservices incidents remain undetected, causing 4-hour downtimes on average according to Gartner, with estimated financial losses of 100k€ per hour for large enterprises.

  • DevOps teams lose 30% productivity on manual debugging, blocking promotions and raising turnover by 25%.

  • In production, the lack of distributed traces leaves security gaps untraced, risking massive GDPR fines.

  • Master it now to avoid these traps and secure your career in professional observability.

Program

Module 1OpenTelemetry Java Fundamentals: Expert SDK and API Architecture (traces, metrics, logs)

Discover the OpenTelemetry Java architecture through practical workshops on the API and SDK, manually implement spans for distributed traces, configure W3C propagators, test export to Jaeger in real exercises on Java microservices, produce your first OTLP dashboards, and validate expert patterns for robust professional observability.

Module 2OpenTelemetry Java Instrumentation: Auto-instrumentation and Spring Boot (Advanced Integration)

Dive into OpenTelemetry Java auto-instrumentation for Spring Boot, activate Java agents without invasive code, customize semantics for HTTP and JDBC, integrate with Kafka for asynchronous traces, conduct hands-on labs on reactive applications, generate expert runtime metrics, and deploy production-ready configurations for Qualiopi-certified enterprises.

Module 3OpenTelemetry Java Metrics and Logs: Distributed Pipelines (Prometheus, Loki, Collectors)

Build OpenTelemetry Java metrics pipelines to Prometheus, implement custom views for histograms and counters, integrate structured logs with trace correlation, test on Kubernetes clusters via Helm charts, optimize batchers for high load, analyze real alerting cases, and produce scalable enterprise monitoring deliverables.

Module 4Advanced OpenTelemetry Java: Production Optimization and Troubleshooting (Custom Exporters, Security)

Master custom OpenTelemetry Java exporters for hybrid backends, secure OTLP and gRPC tokens, diagnose memory leaks in expert traces, optimize adaptive sampling for reduced costs, simulate chaos engineering on on on Java apps, deploy in CI/CD GitHub Actions, and conclude with a capstone project certifying your professional skills in distributed observability.

Methods, materials and delivery

The Training OpenTelemetry Java - Mastering Expert Observability program is delivered onsite or remote (blended-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.

Equipment required

For the smooth delivery of the Training OpenTelemetry Java - Mastering Expert Observability program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Training OpenTelemetry Java - Mastering Expert Observability program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Our method

Training quality, guaranteed at every step

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
