如何在 Grafana 的 Hawkular 指标中监控应用程序的线程数？

【中文标题】如何在 Grafana 的 Hawkular 指标中监控应用程序的线程数？【英文标题】：How to monitor thread count for apps in Hawkular metrics in Grafana? 【发布时间】：2019-07-18 18:52:08 【问题描述】：我正在创建一个仪表板，我可以在其中监控来自 openshift 的 hawkular-metrics 中存在的应用程序的线程数。 （数据源已配置）。
我确实有一个 json 文件，用于为我们的 openshift 项目中的所有 pod 创建用于内存使用的仪表板。但是如何修改它以在 hawkular 指标中显示 pod 的线程数。目前它正在为 openshift 项目中的所有应用程序显示平均、最小和最大内存等。
json文件内标签中用于内存使用的描述符名称为memory/usage。 线程计数的描述符名称是什么？有什么我应该做的修改。 Hawkular 真的会导出线程数相关的指标吗？
这是用于内存使用的 json 文件：

请提供任何有用的建议。 是否有任何文档可以查看 hawkular 提供的指标列表？
【问题讨论】：
【参考方案1】：我不知道 openshift w/hawkular 中的任何线程计数指标。
它在后台使用 heapster，请在此处查看指标：https://github.com/kubernetes-retired/heapster/blob/master/docs/storage-schema.md#metrics。
但我不能 100% 确定它们是否都被报告给 hawkular。
