azure - 具有服务结构集群自动缩放功能的 VMSS

Question

我想要横向扩展或扩展服务结构应用程序。为此，我在 VM 规模集上添加了带有 CPU 指标的自动缩放设置。在 VM 规模集中，我有带有 wadcfg 部分的扩展部分，以及 CPU 指标计数器。并且数据已成功发送到我指定的存储帐户。但是 VMSS 和服务结构集群无法完成横向扩展或扩展选项。我已经完成了 azure 门户中指定的故障排除步骤。 https://azure.microsoft.com/en-us/documentation/articles/virtual-machine-scale-sets-troubleshoot/

在没有服务结构的情况下，相同的 CPU 指标可以正常工作，并且 VM 规模集正在横向扩展。

还检查了订阅限制。但无法找到问题所在。但是，我们收到一封邮件通知，称当 vmss 和服务结构一起部署时，无法读取自动缩放的诊断数据。

Answer 1

Service Fabric 确实支持 AutoScale，只是没有很好的记录。这是一个基本文档 - https://azure.microsoft.com/en-us/documentation/articles/service-fabric-cluster-scale-up-down/，它使用“XmlCfg”元素来配置计数器。不过，还有一种方法可以通过 JSON 来实现，这种方法更具可读性。这是“IaaSDiagnostics”扩展中的“设置” block 的片段。

请注意“DiagnosticMonitorConfiguration”下包含“PerformanceCounters”和“Metrics”元素。
