This is a simple example that demonstrates tracing http request from client to server. The example shows key aspects of tracing such as
- Root Span (on Client)
- Child Span (on Client)
- Child Span from a Remote Parent (on Server)
- SpanContext Propagation (from Client to Server)
- Span Events
- Span Attributes
Example uses
- open-telemetry SDK as trace instrumentation provider,
- httptrace plugin to facilitate tracing http request on client and server
- http trace_context propagation to propagate SpanContext on the wire.
- jaeger exporter to export spans to visualize and store them.
- go 1.12 installed
- GOPATH is configured.
GO111MODULE="" go get -d go.opentelemetry.io
cd $GOPATH/src/go.opentelemetry.io/example/http/
go run ./server/server.go
cd $GOPATH/src/go.opentelemetry.io/example/http/
go run ./client/client.go
The spans should be visible in stdout in the order that they were exported.
