如何在 Grafana 的 Hawkular 指标中监控应用程序的线程数？
How to monitor thread count for apps in Hawkular metrics in Grafana?
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 pods 创建内存使用仪表板。但是我如何修改它以显示 hawkular 指标中 pods 的线程数。目前它正在显示 openshift 项目中所有应用程序的平均、最小和最大内存等。
json 文件中用于标记内存使用的描述符名称是 memory/usage。
线程数的描述符名称是什么？有没有我应该做的修改。 Hawkular 是否真的导出与线程计数相关的指标？

是否有任何文档可供我查看 hawkular 提供的指标列表？
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。
但我不是 100% 确定是否所有这些都被报告为 hawkular。
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 pods 创建内存使用仪表板。但是我如何修改它以显示 hawkular 指标中 pods 的线程数。目前它正在显示 openshift 项目中所有应用程序的平均、最小和最大内存等。

请提供任何有用的建议。 是否有任何文档可供我查看 hawkular 提供的指标列表？
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。
但我不是 100% 确定是否所有这些都被报告为 hawkular。
