From Zero to Hero: OpenTelemetry in .NET
Learn how to implement OpenTelemetry in .NET to capture and export metrics, traces, and logs. This course covers observability concepts, like instrumentation, logging, tracing, and monitoring.
About This Course
OpenTelemetry offers a unified, open-source standard and a suite of technologies for capturing and
exporting metrics, traces, and logs from your cloud-native applications and infrastructure. It is
not a .NET-specific technology but a universal one that every application should follow. Modern
applications are distributed, and capturing and exporting telemetry data can be challenging. With
OpenTelemetry's standardized approach and technological tools, capturing data and exporting it to
participating technology vendors or open-source projects becomes simpler. This course will equip you
with the knowledge and skills to integrate OpenTelemetry into your systems. Gui will explain why
OpenTelemetry is necessary for every modern .NET application, and by the end of the course, you will
be ready to implement it and use it effectively.
