OpenTelemetry tutorial: Troubleshooting APIs With Tyk, Grafana, and Jaeger

Jennifer Craig's tutorial provides a detailed guide on building an observability dashboard for monitoring APIs using OpenTelemetry, Prometheus, and Grafana, along with troubleshooting techniques using Jaeger. The tutorial emphasizes the importance of telemetry data generated at the API gateway level to optimize performance and troubleshoot issues effectively. It covers exporting distributed traces from the Tyk Gateway, setting up the telemetry pipeline in the OpenTelemetry collector, and building a Grafana dashboard to visualize key API metrics. Additionally, it highlights the use of Jaeger for troubleshooting API issues by filtering traces and identifying problems with upstream services. The guide aims to equip developers with the tools and knowledge to enhance API performance and reliability, ultimately benefiting businesses by ensuring high-quality user experiences.
