不支持用于Azure Web应用程序自动缩放的AppInsights自定义指标

Question

我一直在按照本教程按自定义指标（https://docs.microsoft.com/en-us/azure/azure-monitor/platform/autoscale-custom-metric）自动缩放Web应用程序，不幸的是，Azure一直告诉我，已部署的Web应用程序不支持我的自定义指标。谁能帮助我，并指出为什么我的Web应用程序无法按自定义指标进行缩放。如果需要，我位于奥地利，正在将Web应用程序部署到西欧。

谢谢！

修改 我正在将这样的自定义指标从应用程序发送到Application Insights： Code for sending custom metrics。在Azure Web App中，我尝试像下面这样配置自动缩放： Configuring autoscaling by custom metric。从图像上可以看出，我的目标是指标名称空间“ azure.applicationinsights”，该名称空间确实包含我的自定义指标，但是保存后Azure告诉我不可能：enter image description here

Answer 1

我遵循了document，并且能够根据我的自定义指标启用自动缩放功能：

请确保在添加规则时选择正确的选项：

希望这会有所帮助！
