Learn what OpenTelemetry is and why your apps need it
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.
