[HttpInstrumentation] Various http attributes are missing when doing auto-instrumentation ?

[gargut-deshaw]

Hi,

I am using NodeSDK and getNodeAutoInstrumentations for generating metrics in node. I am able to get metrics by seems like lot of attributes are missing like http_route, etc.. I could only see:

http_scheme="http"
http_method="GET"
net_host_name="url"
http_flavor="1.1"
http_status_code="200"
net_host_port=""
le="0"

My code snippet:

// ...


    const sdk = new NodeSDK({
        serviceName: 'my-service',
        resource: new Resource({
            [SEMRESATTRS_SERVICE_NAMESPACE]: 'application',
            [SEMRESATTRS_SERVICE_VERSION]: '0.1',
        }),
        //   traceExporter: new ConsoleSpanExporter(),
        spanProcessors: [new BatchSpanProcessor(traceExporter)],
        metricReader: prometheusMetricExporter,
        instrumentations: [
            getNodeAutoInstrumentations({
                // only instrument fs if it is part of another trace
                '@opentelemetry/instrumentation-fs': {
                    enabled: false,
                },
                '@opentelemetry/instrumentation-redis': {
                    enabled: false,
                },
                '@opentelemetry/instrumentation-net': {
                    enabled: false,
                },
                '@opentelemetry/instrumentation-socket.io': {
                    enabled: false,
                },
                '@opentelemetry/instrumentation-http': {
                    requestHook: (span: Span, request: IncomingMessage) => {
                        span.setAttribute(SEMATTRS_HTTP_ROUTE, 'hello')
                    }
                }
            })
        ],
        resourceDetectors: [envDetector, hostDetector, osDetector, processDetector],
    });

    sdk.start();

Is there a way to add http_route by default ? I am not sure what's missing here. Can someone help here ?

This is fixed. I had an import which was causing express to be loaded before express instrumentation library. Changing import order worked.
