Module tracing 

Distributed Tracing

OpenTelemetry-compatible distributed tracing for kernel execution.

Features

• Span creation for kernel execution
• Trace context propagation in K2K messages
• OTLP export to Jaeger, Zipkin, etc.

Example

use rustkernel_core::observability::tracing::{KernelSpan, TracingConfig};

let config = TracingConfig::otlp("http://jaeger:4317");
config.init().await?;

let span = KernelSpan::start("graph/pagerank", "execute");
// ... kernel execution ...
span.end();
