From HAR to OpenTelemetry Trace: Redefining Browser Observability

This conference talk from SREcon25 Americas explores how to transform HTTP Archive (HAR) files into OpenTelemetry traces for enhanced web application observability. Learn from Antonio Jimenez of Cisco ThousandEyes as he shares practical insights on converting page load request data into OpenTelemetry spans that follow semantic conventions. Discover the architecture used to stream these transformed traces to observability backends like Jaeger via the OpenTelemetry collector. Gain valuable knowledge about leveraging HAR data to achieve deeper insights into web application performance and behavior through modern observability practices.
