End-to-End Observability for an Industrial IoT Platform with OpenTelemetry

Context

Development department — PFE 2026–2027

SIOTH® is Integration Objects’ Industrial IT-OT-IoT platform, built on distributed services including protocol connectors, messaging, Web APIs, a historian and HMI, often deployed on remote sites. This project aims to introduce end-to-end observability using OpenTelemetry, providing a unified health view and correlation across services so that failures and resource leaks can be detected promptly and diagnosis can be automated.

OpenTelemetry capabilities

• Unified logs, metrics and traces correlated by trace context.
• Vendor-neutral OTLP export to monitoring backends.
• .NET SDK with automatic and custom instrumentation.
• Collector for filtering, enriching, sampling and buffering telemetry.
• Semantic conventions and low-overhead sampling.

Main topics

• Audit SIOTH logging and define an observability standard.
• Instrument SIOTH components with the OpenTelemetry .NET SDK.
• Deploy a Collector pipeline with dashboards and alerts.
• Validate the solution using fault-injection tests and overhead measurement.

Deliverables

• Source code for the instrumented components.
• Collector configuration, dashboards and alert rules.
• Project report, design report and test reports.

Expected results

• Centralized, real-time view of SIOTH health.
• Early failure detection and faster troubleshooting.
• Minimal impact on real-time data acquisition.
