I'm using the spring boot autoconfigure with the following dependencies:

    <dependencyManagement>
         <dependency>

SpringBoot autoconfiguration for opentelemetry

The problem is that I can't disable the message:
i.o.e.internal.grpc.OkHttpGrpcExporter : Failed to export metrics. Server responded with UNIMPLEMENTED. This usually means that your collector is not configured with an otlp receiver in the "pipelines" section of the configuration. If export is not desired and you are using OpenTelemetry autoconfiguration or the javaagent, disable export by setting OTEL_METRICS_EXPORTER=none. Full error message: unknown service opentelemetry.proto.collector.metrics.v1.MetricsService.

I already tried setting up the environment variable OTEL_METRICS_EXPORTER=none, but this variable isn't interpreted by opentelemetry-spring-boot-start, because the error continue being showed at the console log.

When I execute a curl to the jaeger container a received the error message Received HTTP/0.9 when not allowed.

The question are:
Is there a way to connect and send the metrics successfully to the jaeger ?
What library should I use to fix this problem?
Is there some example to resolve this message using opentelemetry-spring-boot-starter and jaeger?

I'm waiting for your help.
Thank you

hi @wesleyzup! it looks like this is configurable using otel.exporter.otlp.metrics.enabled=false:

opentelemetry-java-instrumentation/instrumentation/spring/spring-boot-autoconfigure/src/main/java/io/opentelemetry/instrumentation/spring/autoconfigure/exporters/otlp/OtlpExporterProperties.java

Line 29 in 53353ac

private final SignalProperties metrics = new SignalProperties();

Hi @trask, thank you for you response.
What would I have to do to send the metrics to jaeger using OTLP and avoid the mentioned error above?
Because the default metrics endpoint is localhost:4317, but unfortunately the jaeger metrics connection isn't realized.
Is there some tips to help me ?

In your place I'd firstly try to figure out whether Jaeger supports metrics at all. If the answer is no then just disable sending metrics.
