Overview ¶
Package fasthttp provides functions to trace the valyala/fasthttp package (https://github.com/valyala/fasthttp)
Example ¶
package main
import (
"fmt"
fasthttptrace "gopkg.in/DataDog/dd-trace-go.v1/contrib/valyala/fasthttp.v1"
"gopkg.in/DataDog/dd-trace-go.v1/ddtrace/tracer"
"github.com/valyala/fasthttp"
)
func fastHTTPHandler(ctx *fasthttp.RequestCtx) {
fmt.Fprintf(ctx, "Hello World!")
}
func main() {
// Start the tracer
tracer.Start()
defer tracer.Stop()
// Start fasthttp server
fasthttp.ListenAndServe(":8081", fasthttptrace.WrapHandler(fastHTTPHandler))
}
Output:
