Trying to setup java-agent with JBOSS: Error message: INTERNAL: http2 exception

[faisal-yusufzai]

Hello everyone,

I am currently trying to set up my java-agent for metric gathering with my jboss standalone.conf file where the flags needed for otel are added to it. These are the current flags I am using to start up my JBOSS application and it is not crashing it, however, I am not able to see the metrics sent to my otel-collector ( I only care about metrics but set up the logs and traces to not see anymore errors).
-javaagent:opentelemetry-javaagent-all.jar \ -Dotel.exporter=otlp \ -Dotel.traces.exporter=otlp \ -Dotel.metrics.exporter=otlp \ -Dotel.logs.exporter=otlp \ -Dotel.exporter.otlp.protocol=http/protobuf \ -Dotel.exporter.otlp.traces.protocol=http/protobuf \ -Dotel.exporter.otlp.metrics.protocol=http/protobuf \ -Dotel.exporter.otlp.logs.protocol=http/protobuf \ -Dotel.exporter.otlp.endpoint=http://172.17.x.xxxx:4318 \ -Dotel.exporter.otlp.metrics.endpoint=http://172.17.x.xxx:4318/v1/metrics \ -Dotel.exporter.otlp.traces.endpoint=http://172.17.x.xxxx:4318/v1/traces \ -Dotel.exporter.otlp.logs.endpoint=http://172.17.x.xxxx:4318/v1/logs \ -Dotel.logs.export.interval=1 \ -Dotel.traces.export.interval=1 \ -Dotel.jmx.config=config_file.yaml \ -Dotel.jmx.discovery.delay=0 \ -Dotel.metric.export.interval=1

The config file is just the example one below:
`---
rules:

• bean: java.lang:type=Threading
  mapping:
  ThreadCount:
  metric: my.own.jvm.thread.count
  type: updowncounter
  desc: The current number of threads
  unit: "1"
  `

The error I am getting is:
2025-02-04 14:04:02,887 ERROR [stderr] [opentelemetry.auto.trace 2025-02-04 14:04:02:887 +0000] [grpc-default-executor-0] WARN io.opentelemetry.exporter.otlp.trace.OtlpGrpcSpanExporter - Failed to export spans. Error message: INTERNAL: http2 exception
But I am also getting it for the metrics and logs as well. Please let me know if you see something wrong as I just started using otel-collector and java-agent. Thank you!
