telemetry
Telemetry is a collection of performance monitoring collectors and sinks. It is inspired by https://github.com/gocraft/health but written to take advantage of datadogs tagging.
Sinks
The only supported sink currently is datadog:
t := telemetry.New("app:myapp")
t.AddSink(sink.Datadog("mydatadog.local", 1234))Collectors
Runtime collector fetches stats from the golang runtime environment, eg memory usage and active goroutines.
runtime
collector.Runtime(t)gorilla
// Middleware to collect timing for named routes from gorilla mux
router := mux.NewRouter()
router.Handle("/", handler).Name("test.route")
handler := gorilla.Handler(t, router, func(w http.ResponseWriter, r *http.Request) {
// You can log your own metrics from any handler after this.
gorilla.ContextForRequest(r).Gauge("test_metric", 2)
})
