InfoQ: Cloudflare Traces Turns the Proxy Layer into OpenTelemetry Spans, with New Volume-Based Pricing
Cloudflare put Traces into open beta, extending its automatic tracing from Workers to security rules, transformations, cache, routing and origin handling, emitted as OpenTelemetry spans. Traces accept and forward W3C traceparent headers, and Trace Rules allow targeted sampling. Pricing moves to ingestion and retention volume starting December 1.
What changes for platform teams
Platform teams that use Cloudflare in front of services can get proxy-layer spans in their existing OpenTelemetry backends, with sampling controls to limit volume. Teams should estimate ingestion and retention costs before December 1, since billing changes from the current model to volume-based.
