无法将otlp资源属性映射到loki标签

Question

我使用的是一个spring引导应用程序，它使用opentelem遥测代理将包括日志在内的遥测数据发送给Opentelem遥测收集器。

日志成功地传输到opentelem遥测收集器并在grafana loki接收，但是Loki标签没有用OTLP资源和日志属性进行更新。

当前配置-> Loki标签-> host_name: host.name (如otlp资源标签中所述)：Loki标签-> host_name: 06605506424f或任何其他属性名(例如: service.name )

操作系统收集器配置文件：

我认为这是已知臭虫在洛基出口商为OpenTelemetry。解决方法是在logRecord属性部分中定义资源标签，直到问题得到解决为止。
