使用开放遥测代理运行的Java 8应用程序导出新遗留数据时出现464错误

Question

当我运行Java 11时，它运行得很好：

java -javaagent:./otel/opentelemetry-javaagent.jar \
-DOTEL_EXPORTER_OTLP_COMPRESSION=gzip \
-DOTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT=4095 \
-DOTEL_JAVA_DISABLED_RESOURCE_PROVIDERS=io.opentelemetry.sdk.extension.resources.ProcessResourceProvider \
-DOTEL_EXPERIMENTAL_EXPORTER_OTLP_RETRY_ENABLED=true \
-DOTEL_EXPORTER_OTLP_METRICS_TEMPORALITY_PREFERENCE=DELTA \
-Dotel.traces.exporter=otlp \
-Dotel.metrics.exporter=otlp \
-Dotel.logs.exporter=otlp \
-Dotel.exporter.otlp.endpoint=https://otlp.nr-data.net:4317 \
-Dotel.resource.attributes=service.name=app-service \
-Dotel.exporter.otlp.headers=api-key=<api-key> \
-Dotel.javaagent.debug=false -jar ./target/app-service-0.0.1-SNAPSHOT.jar

但是当我在Java 8中运行时，它失败了：

ENTRYPOINT ["java", \
  "-Dotel.traces.exporter=otlp", \
  "-Dotel.metrics.exporter=otlp", \
  "-Dotel.logs.exporter=otlp", \
  "-Dotel.exporter.otlp.endpoint=https://otlp.nr-data.net:4317", \
  "-DOTEL_EXPORTER_OTLP_COMPRESSION=gzip", \
  "-DOTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT=4095", \
  "-DOTEL_JAVA_DISABLED_RESOURCE_PROVIDERS=io.opentelemetry.sdk.extension.resources.ProcessResourceProvider", \
  "-DOTEL_EXPERIMENTAL_EXPORTER_OTLP_RETRY_ENABLED=true", \
  "-DOTEL_EXPORTER_OTLP_METRICS_TEMPORALITY_PREFERENCE=DELTA", \
  "-Dotel.exporter.otlp.headers=api-key=<api-key>", \
  "-Dotel.resource.attributes=service.name=app-service", \
  "-Dotel.javaagent.debug=false", \
  "-javaagent:opentelemetry-javaagent.jar", "-jar", "app-service.jar"]

获取以下错误：

[otel.javaagent] [OkHttp https://otlp.nr-data.net:4317/...] WARN io.opentelemetry.exporter.internal.grpc.OkHttpGrpcExporter - Failed to export logs. Server responded with HTTP status code 464.

Dockerfile：

FROM maven:3.8.1-jdk-8-slim AS build
WORKDIR /opt/app
COPY src src
COPY pom.xml .
RUN mvn -f pom.xml clean install

FROM openjdk:8-jdk-alpine
COPY --from=build /opt/app/target/app-service-*.jar app-service.jar
COPY ./otel/opentelemetry-javaagent.jar opentelemetry-javaagent.jar
EXPOSE 8080
ENTRYPOINT ["java", "-javaagent:opentelemetry-javaagent.jar", "-jar", "app-service.jar"]

我正在使用opentelemetry版本: 1.12.0。

知道哪个版本的新文物开放遥测代理为Java 8工作吗？

以下是报告问题的解决方案：https://discuss.newrelic.com/t/java-464-error-with-new-relic-data-export-from-the-java-8-application-running-with-opentelemetry-agent/187361/3?u=valsaraj

Answer 2

464表示协议混合- HTTP与GRPC之间存在问题。显式使用HTTP，因为grpc导出程序存在此问题：

otel.exporter.otlp.protocol=http/protobuf

也许你有什么东西(代理，防火墙，WAF，.)是什么导致来自容器的GRPC连接出现问题。
