PulseGuard: Java Observability Demo with SigNoz
PulseGuard is a Java-based observability demo application that uses OpenTelemetry and SigNoz to monitor a simulated e-commerce checkout workflow in real time. Built with Java 21, Spring Boot, Maven, Docker and the OpenTelemetry Java Agent, the project generates distributed traces and metrics which are exported via OTLP to a locally running SigNoz instance. The demo includes simulated incident endpoints, dashboards, alerts and service overviews to illustrate tracing, latency analysis, and end-to-end troubleshooting. The author thanks the SigNoz team for organizing a hackathon that enabled the project.
Technical demo illustrating open-source observability practices with SigNoz and OpenTelemetry; valuable as a practical example for engineers but not broadly industry-changing.

Key Takeaways & Evidence Grounding
- PulseGuard is a Java-based observability demo that uses SigNoz and OpenTelemetry to monitor a simulated e-commerce checkout system in real time.
- The project is built with Java 21, Spring Boot, Maven, OpenTelemetry Java Agent, SigNoz, Docker, WSL, and REST APIs.
- Telemetry (traces and metrics) is collected by the OpenTelemetry Java Agent and exported via OTLP to a locally running SigNoz instance.
- PulseGuard simulates checkout workflows and includes endpoints to generate realistic incidents (degraded payment behavior, recovery actions) for testing observability.

Instrumenting MERN E‑Commerce with SigNoz
A developer case study describing how the author instrumented a MERN-stack e-commerce application called Ram Store with SigNoz and OpenTelemetry during the Agents of SigNoz Hackathon 2026. The project used a self-hosted SigNoz instance (Docker) and the OpenTelemetry Node SDK with automatic instrumentation for Express, HTTP, and MongoDB, exporting via OTLP gRPC. The instrumentation enabled distributed traces, runtime metrics, and structured logs (Winston) correlated inside SigNoz. The post covers setup steps, observed telemetry (traces, metrics, logs), challenges (Docker networking, configuration), lessons learned, and planned improvements like custom dashboards and alerting. Project source code and a demo video are linked.
Hands-on Review: SigNoz Observability Experience
A developer published a hands-on review of SigNoz, an open-source observability platform built on OpenTelemetry. The author reports a simple Docker-based setup, rapid connection of a sample application, and unified visibility of logs, metrics, and traces in a single dashboard. Distributed tracing stood out as the most valuable feature, allowing full request-path visibility across services. The review highlights built-in dashboards (CPU, memory, latency, throughput, error rates) and alerting capabilities, and emphasizes the importance of observability for AI and cloud-native applications.
Instrumenting Kotlin Spring Boot with OpenTelemetry
This tutorial demonstrates how to move beyond basic logging by instrumenting a Kotlin + Spring Boot scheduled job using the OpenTelemetry Java Agent. The author shows why plain logs fail in concurrent and multi-instance environments, explains OpenTelemetry's three signal types (traces, metrics, logs) and architecture (instrumentation, Collector, exporters), and provides step-by-step instructions: clone the sample repo, enable async execution, download and attach the opentelemetry-javaagent.jar to the JVM, configure bootRun JVM args (service name and exporters), and update log patterns to include MDC-based trace_id and span_id. Sample log output illustrates how trace IDs let you filter interleaved logs to isolate a single execution. The article links the full example code on GitHub and suggests next steps such as adding structured fields and exporting telemetry to backends like Jaeger or Grafana.
