opentelemetry-java | OpenTelemetry Java SDK | REST library

I am trying to extend OpenTelemetry java agent and I don't see any indication it is trying to load my jar. I am running the following cmd:

I am trying to integrate opentelemetry in in my spring boot application with jaeger. I am running jaeger on my local machine (started with binary not with docker) and I am starting my spring boot application with following command:

java -javaagent:/Users//temp/opentelemetry-javaagent-all.jar -Dotel.traces.exporter=jaeger -Dotel.exporter.jaeger.endpoint=localhost:14250 -Dotel.resource.attributes=service.name=playground-app -Dotel.javaagent.debug=false -Dotel.metrics.exporter=jaeger -Dotel.exporter.otlp.endpoint=localhost:14250 -Dotel.exporter.otlp.traces.endpoint=localhost:14250 -Dotel.exporter.otlp.metrics.endpoint=localhost:14250 -jar playground-app-0.0.1-SNAPSHOT.jar

when I hit a endpoint I am getting following error on command line:

[opentelemetry.auto.trace 2021-11-15 17:11:29:043 +0530] [grpc-default-executor-0] WARN io.opentelemetry.exporter.otlp.trace.OtlpGrpcSpanExporter - Failed to export spans. Error message: UNIMPLEMENTED: unknown service opentelemetry.proto.collector.trace.v1.TraceService

Here is the dependencies section from build.gradle

I would like to use opentelemetry-java-instrumentation with AWS OTEL collector and X-Ray. Unfortunately, AWS OTEL aws-xray exporter is not able to export generated traces to X-Ray because generated trace ID is invalid X-Ray trace ID:

I am trying to export metrics and traces from my Akka app written in Scala using OpenTelemetry agent with the purpose of consuming the data in OpenSearch.

Technology stack for my application:

• Akka - 2.6.*
• RabbitMQ (amqp client 5.12.*)
• PostgreSQL (jdbc 42.2.*)

I've added OpenTelemetry instrumentation runtime dependency to build.sbt:

I've got a Spring Boot application that'd I'd like to automatically generate traces for using the OpenTelemetry Java agent, and subsequently upload those traces to Google Cloud Trace.

I've added the following code to the entry point of my application for sending traces:

I am very new to using OpenTelemetry and have just tried configuring it to send traces to my Zipkin server. Unfortunately , after configuring the agent by specifying zipkin exporter details , I could see an exception in the console. I used Petclic as sample spring boot and have followed the documentation here https://github.com/open-telemetry/opentelemetry-java-instrumentation

Here is the command that I used to start spring-boot app(I have my zipkin server running at localhost:9411):

java -javaagent:opentelemetry-javaagent-all.jar -Dotel.exporter=zipkin -Dotel.exporter.zipkin.endpoint=localhost:9411 -jar spring-petclinic-2.4.2.jar

Exception in the console (It is trying to connect to gRpc exporter instead of Zipkins):

I have an application which is made up of multiple services built in proprietary language. I want to collect traces and ingest into Jaeger or APM solution. There is no instrumentation library. However, these services produce traces in a proprietary format. I want to convert these traces to OpenTelemetry traces and ingest into Jaeger or APM solution.

I started using OpenTelemetry-Java SDK.

I'm new to the world of Opentelemetry and would like to send the Spring-petclinic instrumentation data to Jaeger which is running on my remote cloud system

Here is the bat file: java -javaagent:opentelemetry-javaagent-all.jar -Dotel.exporter=jaeger -Dotel.exporter.jaeger.endpoint=50.18.XXX.XX:14250 -Dotel.otlp.span.timeout=4000 -Dotel.jaeger.service.name=otel-ui -jar target/spring-petclinic-2.4.0.BUILD-SNAPSHOT.jar

When I run the bat file, I'm abe to open the petclinic app in browser (http://localhost:8080), I get the following error in the console: [opentelemetry.auto.trace 2021-01-06 17:22:21:008 +0530] [grpc-default-executor-1] WARN io.opentelemetry.exporter.otlp.OtlpGrpcSpanExporter - Failed to export spans. Error message: UNAVAILABLE: io exception

How to resolve this issue? Are there any other dependencies to be the added to the petclinic pom.xml or to the code?

I wrote a javaagent as below to capture the execution time of the execute method of the apache org.apache.http.client.HttpClient. It is capturing the time, but it's running three times.
