我是OpenTelemetry的新手。我试图做安装使用yaml文件appraoch，但面临'连接拒绝'问题，同时连接apm到elasticsearch。
到目前为止我所取得的成就：a）能够在OtelCollector中接收数据。B）能够在Prometheus中接收数据。
面临的问题：a）无法将APM与Elasticsearch连接。enter image description here

Stack：Otel Collector Elastic APM Elasticsearch Prometheus

我附上所有的yml文件作为参考。请帮助我解决问题，并指出我现在正在做的其他错误。

我尝试使用yaml文件配置OpenTelemetry。期望：数据应该从Otel-Collector转发到elasticsearch。
