I got below error, I am using go v1.10.4 linux/amd64.
I am not behind any firewall or whatsoever. New Relic in java server (same network segment) that we have runs fine.
We have tried:
{"exception":{"message":"Server Error","error_type":"RuntimeError"}}
Below is our code:
config := newrelic.NewConfig(os.Getenv("NEW_RELIC_APP_NAME"), os.Getenv("NEW_RELIC_KEY"))
config.Logger = newrelic.NewDebugLogger(os.Stdout)
app, err := newrelic.NewApplication(config)
if err != nil {
fmt.Println("Failed to create newrelic application", err)
os.Exit(1)
}
.................
httpListener, err := net.Listen("tcp", *httpAddr)
if err != nil {
oldlog.Print("Error: ", err)
logger.Log("transport", "HTTP", "during", "Listen", "err", err)
os.Exit(1)
}
g.Add(func() error {
logger.Log("transport", "HTTP", "addr", *httpAddr)
return http.Serve(httpListener, nrgorilla.InstrumentRoutes(httpHandler, app))
}, func(error) {
httpListener.Close()
})
}
However this what we got,note some_key was removed:
(28422) 2019/07/29 18:08:50.058559 {"level":"warn","msg":"application connect failure","context":{"error":"Post https://collector-001.eu01.nr-data.net/agent_listener/invoke_raw_method?license_key=some_key\u0026marshal_format=json\u0026method=connect\u0026protocol_version=17: net/http: request canceled (Client.Timeout exceeded while awaiting headers)"}}
I think it is due to DNS network timeout.
You can easily test this out by using the following steps (in Ubuntu)
Disable the “Automatic” toggle switch and enter the DNS resolvers' IP addresses, separated by a comma. We’ll use the Google DNS nameservers:
8.8.8.8,8.8.4.4
If it works, then you may be able to reset the DNS to "Automatic"
