为什么InsightsMetrics不显示任何Cassandra指标？

Question

将Cassandra作为状态集部署在AKS中，为其提供导出器并按照建议的here启用基于Prometheus的指标之后，我想可视化一些Cassandra特定指标，以便可以开始理解我期间的Cassandra行为具体测试。

因为OMS代理没有打印日志，所以我尝试使用不同的配置选项进行实验，以指定Prometheus抓取端点。实际上，我尝试使用内部K8s服务和外部Azure内部负载均衡器。

例如：

prometheus-data-collection-settings: |-
    # Custom Prometheus metrics data collection settings
    [prometheus_data_collection_settings.cluster]
        # Cluster level scrape endpoint(s). These metrics will be scraped from agent's Replicaset (singleton)

        #Interval specifying how often to scrape for metrics. This is duration of time and can be specified for supporting settings by combining an integer value and time unit as a string value. Valid time units are ns, us (or µs), ms, s, m, h.
        interval = "1m"

        ## Uncomment the following settings with valid string arrays for prometheus scraping
        fieldpass = ["*"]

        #fielddrop = ["metric_to_drop"]

        # An array of urls to scrape metrics from.
        urls = ["http:/ 10.192.85.7:8080/metrics"]

        # An array of Kubernetes services to scrape metrics from.
        kubernetes_services = ["http://cassandra-http-metrics.cassandra.svc.cluster.local:8080/metrics"]

使用这些配置，我希望看到指标显示在Azure Monitor中；但不幸的是，Documentation并不能解决这种类型的集成问题，因为带有Prometheus的容器的Azure Monitor仍处于预览状态。
