Overview ¶
Example ¶
This example shows how to instrument an HTTP server that uses github.com/labstack/echo with Instana
sensor := instana.NewSensor("my-web-server")
// Use instaecho.New() to create a new instance of Echo. The returned instance is instrumented
// with Instana and will create an entry HTTP span for each incoming request.
engine := instaecho.New(sensor)
// Use the instrumented instance as usual
engine.GET("/myendpoint", func(c echo.Context) error {
return c.JSON(200, map[string]string{
"message": "pong",
})
})
log.Fatalln(engine.Start(":0"))
