如何在Grafana的Hawkular指标中监控应用程序的线程数?

标签: openshift grafana metrics grafana-api hawkular

我正在创建一个仪表板,可以在其中监视openshift的hawkular指标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,如何修改它以以小节度量显示豆荚的线程数。目前,它在openshift项目中显示所有应用程序的平均,最小和最大内存等。

用于json文件内部标签中的内存使用的描述符名称为内存/使用情况。 线程计数的描述符名称是什么?还有我应该做的任何修改。 Hawkular实际导出线程计数相关指标吗?

这是用于内存使用的json文件:

请提供任何有用的建议。 我可以查看hawkular提供的指标列表的任何文档吗?

我不知道openshift w / hawkular中的任何线程计数指标。

它在后台使用堆纸器,请参见此处的指标:https://github.com/kubernetes-retired/heapster/blob/master/docs/storage-schema.md#metrics

但是我不确定100%是否全部都报告为鹰派。
