I do not see any HTTP server request/response metrics

[Prateek-Wayne]

I do not see any HTTP server request/response metrics, such as:

http.server.request.duration

Otel is sending only jvm related metrics
example

jvm_memory_committed_total
{instance="f3eb0e4f-c802-43ee-ae17-0d5d857bf1d3",
job="local-inventory-management-service",
jvm_memory_pool_name="G1 Eden Space",
jvm_memory_type="heap"}

jvm_class_unloaded_total
{instance="f3eb0e4f-c802-43ee-ae17-0d5d857bf1d3",
job="local-inventory-management-service"
}

I am using the spring boot starter

dependencyManagement {
	imports {
		mavenBom("io.opentelemetry.instrumentation:opentelemetry-instrumentation-bom:2.20.0")
		mavenBom "io.netty:netty-bom:4.2.4.Final"
	}
}


dependencies{
	implementation 'io.opentelemetry.instrumentation:opentelemetry-spring-boot-starter'
	implementation 'io.opentelemetry:opentelemetry-sdk-extension-autoconfigure'
	implementation 'org.springframework.boot:spring-boot-starter-actuator' // not sure this is needed
	implementation 'io.micrometer:micrometer-registry-prometheus' //not sure this is needed
	runtimeOnly 'io.opentelemetry:opentelemetry-exporter-otlp:1.43.0'
	runtimeOnly 'io.opentelemetry:opentelemetry-sdk-metrics'
}

My application .property file

application.properties

otel.service.name= my-service-name
otel.exporter.otlp.endpoint= https://myurl-where-otel-is-deployed
otel.exporter.otlp.headers=Authorization=Basic user:pass
otel.metrics.exporter=otlp
otel.traces.exporter=otlp
otel.logs.exporter=none
otel.instrumentation.spring-web.enabled=true
otel.instrumentation.spring-web.metrics.enabled=true
otel.instrumentation.http-server.metrics.enabled=true
otel.instrumentation.spring-webclient.enabled=true
otel.instrumentation.spring-webclient.metrics.enabled=true
otel.java.global-autoconfigure.enabled=true

Hi @laurit
Thanks for the quick reply! :)
I’ve created a minimal reproducible example to demonstrate the issue. You can find it here:
https://github.com/Prateek-Wayne/springboot-otel-http-repro

also sharing the metrics I am seeing.

processedSpans_total{dropped="0",instance="ff25f3ef-453c-492f-921f-1557ad553721",job="sample-app",processorType="BatchSpanProcessor"}

Please let me know am I missing anything important while configuring otel
I am following this documentation
https://opentelemetry.io/docs/zero-code/java/spring-boot-starter/getting-started/

@Prateek-Wayne I spun up your project, and when I hit the /ping endpoint a few times, i see http.server.request.duration show up as expected

@laurit @jaydeluca
Sorry for the late response 🙏.
I was investigating this issue from our end and wanted to reply once I was sure.

Thanks a lot for the quick support and clarification 🙏.
I’ve verified that the issue is with our OTel deployment, not the instrumentation. Closing this now.
