A small convenience layer that sits on top of newrelic-go-agent, to make it easy to create transactions for NewRelic in Go.
This is alpha software. It has not been tested in a production environment, or any environment for that matter.
You'll need to install the nr_agent_sdk first.
This package will only work on linux platforms. It is also disabled by default. To enable it, use the build flag newrelic_enabled:
go build -tags newrelic_enabled ./...
See ./example/main.go for a more complete example.
import "github.com/remind101/newrelic"
func main() {
newrelic.Init("newrelic app name", "newrelic license key")
tx := newrelic.NewTx("/my/transaction/name")
tx.Start()
defer tx.End()
// Add a segment
tx.StartGeneric("middleware")
// Do some middleware stuff...
tx.EndSegment()
}This packages works well as an httpx middleware.
Here is an example using httpx, a context aware http handler.
r := httpx.NewRouter()
r.Handle("/articles", &ArticlesHandler{}).Methods("GET")
r.Handle("/articles/{id}", &ArticleHandler{}).Methods("GET")
var h httpx.Handler
// Add NewRelic tracing.
h = middleware.NewRelicTracing(r, r, &newrelic.NRTxTracer{})
// Wrap the route in middleware to add a context.Context.
h = middleware.BackgroundContext(h)
http.ListenAndServe(":8080", h)The above example will create web transactions named GET "/articles" and GET "/articles/{id}".
