内部速度链接未填充以获取 Loki 中的痕迹

Question

我已将 Grafana Loki 和 Tempo 集成到 EKS 集群中。我可以从 Loki 查询服务，但 Tempo 的内部跟踪 URL 未填充到 Loki 中。我部署了 Flunetbit，它将日志推送到 Loki。

我正在使用 Ingress 控制器访问 Grafana。已部署 otel-collector 以从集群获取跟踪信息。有人可以就此提出建议吗，自从我陷入这个问题以来已经好几天了。！

我认为您的 Loki 数据源中缺少某些内容：

    derivedFields:
      - datasourceUid: tempo
        matcherRegex: 'traceID=(\\w+)'
        name: TraceID
        url: $${__value.raw}
        urlDisplayLabel: Find this trace in Tempo
