echo Instrumentation Example

This is an example of producing distributed traces using the SignalFx Tracing Library for Go. This example provides an instrumented API server that serves a simple in-memory store exposing a CRUD API.

Start Server

To run this example locally and send traces to your available Smart Agent or Gateway, please clone this repository and from this directory do the following:

$ cd server
$ go get
$ go run server.go

By default the service name is simple-crud-api and the tracing endpoint is http://localhost:9080/v1/trace. These values can be overridden by setting ECHO_SERVICE_NAME and ECHO_TRACING_ENDPOINT environment variables

Generate Traces

The following operations can be performed to generate traces.

curl -X POST \

  -d '{"record":{"name":"Joe Doe", "age" : 29}}' \
  localhost:1323/records
