Drop errors based on their Exception

[orafaaraujo]

Hi,

I'm trying to drop some errors, but they continue to appear in the Dashboards.

I'm using a custom TracedRequestListener on DatadogInterceptor and TracingInterceptor.

DatadogInterceptor(
    firstPartyHosts = tracedHosts,
    tracedRequestListener = customTracedRequestListener,
)

TracingInterceptor(
    tracedHosts = tracedHosts,
    tracedRequestListener = customTracedRequestListener,
)

private val customTracedRequestListener = object : TracedRequestListener {
    override fun onRequestIntercepted(
        request: Request,
        span: Span,
        response: Response?,
        throwable: Throwable?,
    ) {
        if (throwable is IOException) {
            (span as? DDSpan?)?.drop()
        }
    }
}

I aim to remove all java.io.IOException: Canceled generated from Coroutines when the user leaves the screen in a middle of a request. Those exceptions are expected, so we do not want to send them to Datadog.

Am I missing something? What's the correct approach in this situation?

Thank you

Hello @orafaaraujo!

Can you please tell us which dashboard are you checking? Is it RUM or Traces (APM)?

Please also share the SDK version used.

Hey @0xnm

It's on the RUM dashboard.

I'm using the SDK version 1.19.3, plugin version 1.10.0.

TracedRequestListener works with spans, which are used for distributed tracing (APM) in case of OkHttp instrumentation.

For your use-case, since it is RUM, you may use setRumErrorEventMapper and return null in the implementation for the events which you want to drop based on your criteria.

Hey @0xnm

Now it's working like a charm. Thank you for your help on that. Have a nice weekend!
