Learning objectives

  • Master the installation and initial configuration of Sentry for monitoring web performance in an enterprise environment.
  • Develop professional skills in instrumenting applications with Sentry Performance.
  • Design custom alerts and dashboards for proactive monitoring of key metrics.
  • Optimize application performance through analysis of traces and bottlenecks identified by Sentry.
  • Implement Sentry integrations with CI/CD tools for certified monitoring training.
  • Evaluate and resolve performance issues in real professional contexts.

The Learni story

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

Why this program matters

  • 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.

Program

Module 1Introduction to Sentry Performance: Basic Installation and Configuration (Docker, Initial Projects)

Discover Sentry Performance through a guided installation with Docker and Heroku, configure your first web project, integrate the JavaScript SDK to capture transactions, perform practical exercises on a simulated e-commerce site, analyze initial loading metrics, and produce an initial dashboard to visualize the application's overall performance.

Module 2Sentry Performance Instrumentation: Traces and Spans for Web Applications (SDK Tools, Profiling)

Dive into instrumentation with Sentry SDKs for frontend and backend, capture distributed traces on Node.js and React, profile slow functions via exercises on real APIs, configure custom spans for critical requests, test under moderate load conditions, and generate detailed reports on bottlenecks for immediate optimization.

Module 3Advanced Sentry Performance Monitoring: Alerts and Key Metrics (Dashboards, Thresholds)

Create custom dashboards with LCP, FID, and CLS metrics, set up real-time alerts for performance degradations, integrate Sentry with Grafana for a unified view, simulate peak traffic scenarios on a hybrid mobile app, analyze historical trends, and deploy automated rules to notify the DevOps team in case of critical anomalies.

Module 4Optimization via Sentry Performance: Bottleneck Analysis and Caching (Recommendations, A/B Testing)

Identify and resolve bottlenecks using Sentry's flame graphs, optimize frontend caching with exercises on Varnish and CDN, test A/B strategies to compare performance before/after, integrate release monitoring to track update impacts, apply fixes to a concrete e-shop case, and measure real loading speed gains.

Module 5Deployment and Integrations for Sentry Performance: CI/CD and Scaling (GitHub Actions, Kubernetes)

Integrate Sentry into CI/CD pipelines with GitHub Actions and Jenkins, configure monitoring in a Kubernetes environment, simulate horizontal scaling under load via Locust, deploy sourcemaps for precise debugging, train on data export to third-party tools like Slack, and finalize with a deliverable capstone project including a complete optimization report for the company.

Evaluation method

  • Daily interactive quizzes on Sentry Performance concepts to validate theoretical knowledge.
  • Practical case studies evaluated by experts in real-time during workshops.
  • Final project monitoring a web application, graded on professional criteria and certifying.

Learning method

  • Practical methods with 70% hands-on exercises on real environments.
  • Concrete use cases from Fortune 500 companies using Sentry.
  • Individualized pedagogical support in small groups of max 10 participants.
  • Post-training resources: videos, cheat-sheets, and alumni community.

Methods, materials and delivery

The Training Sentry Performance - Mastering Web Performance Monitoring 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.

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.
