部署环境与操作 #

基于2台Vagrant虚拟机和两个基础SpringBoot应用搭建演示项目，通过Terraform创建Application Insights资源。

在每台虚拟机上执行以下Docker命令部署Collector：

sudo docker run -d -v /etc/otel_config.yaml:/etc/otel/config.yaml -e OTEL_EXPORTER_OTLP_ENDPOINT=0.0.0.0:4317 -p 4317:4317 otel/opentelemetry-collector-contrib --config /etc/otel/config.yaml

问题现象 #

从Collector的Docker日志可以看到，已成功接收指标和日志数据：

debug   azuremonitorexporter@v0.77.0/metric_to_envelopes.go:77  Metric is packed        {"kind": "exporter", "data_type": "metrics", "name": "azuremonitor", "name": "otlp.exporter.seen", "value": 16020}
debug   azuremonitorexporter@v0.77.0/factory.go:128     --------- Transmitting 59 items ---------       {"kind": "exporter", "data_type": "logs", "name": "azuremonitor"}

但这些指标和日志并未转发至Application Insights，只有追踪（trace）信息能成功推送。
