Setting up appdash in Go, not seeing traces

[sethgrid]

Hi all. Couldn't ask on slack as the link on the README is dead. When I used the in-app example code, I got traces to a local running appdash instance. I'm now trying to connect to a already running appdash instance and not getting traces. I think I'm setting up the tracer wrong. Any help?

// my app.go
tracer := appdashtracer.NewTracer(appdash.NewRemoteCollector("appdash.service.consul:8700"))

edit Saw an example using chunked collector. Tried that, it did not work either. Still not seeing traces (appDashAddr is the same as above, appdash.service.consul:8700).

// my app.go
collector := appdash.NewRemoteCollector(appDashAddr)
chunkedCollector := appdash.NewChunkedCollector(collector)
tracer := appdashtracer.NewTracer(chunkedCollector)

2nd edit updated to the following. Still no traces. No logs either.

logger := log.New(os.Stdout, "appdash", log.Lshortfile|log.Ltime)
collector := appdash.NewRemoteCollector(appDashAddr)
chunkedCollector := appdash.NewChunkedCollector(collector)
tracer := appdashtracer.NewTracerWithOptions(chunkedCollector, appdashtracer.Options{
    Verbose: true,
    Logger:  logger,
})

end edits

I can hit appdash.service.consul:8700 and it comes up. But no traces to be found.

The separately running appdash instance looks like:

// separate server running appdash
func main() {
    var minEvictAge time.Duration
    var port int

    flag.DurationVar(&minEvictAge, "min-evict-age", 5*time.Minute, "set the amount of time the tracer will hold onto traces")
    flag.IntVar(&port, "port", 8700, "the port on which the for app dash tracer will run")
    flag.Parse()

    memStore := appdash.NewMemoryStore()
    store := &appdash.RecentStore{
        MinEvictAge: minEvictAge,
        DeleteStore: memStore,
    }

    appDashURLString := fmt.Sprintf("http://localhost:%d", port)
    appDashURL, err := url.Parse(appDashURLString)
    if err != nil {
        log.Fatal(err)
    }
    tapp, err := traceapp.New(nil, appDashURL)
    if err != nil {
        log.Fatal(err)
    }
    tapp.Store = store
    tapp.Queryer = memStore

    log.Printf("starting on :%d", port)
    log.Fatal(http.ListenAndServe(fmt.Sprintf(":%d", port), tapp))
}
