我们已将Linux上的Azure功能部署到Azure容器实例。
不幸的是，使用默认的cloud_RoleName，应用程序洞察力日志记录根本没有显示我的ILogger。为了按容器查询日志，我需要将cloud_RoleName设置为容器图像的名称。
如何在不必直接使用遥测客户端的情况下设置此遥测属性？
答案 0 :(得分：2)
如kudu中所述，我们通过在ContainerProperties EnvironmentVariable数组的cloud_RoleName部分的Microsoft.ContainerInstance/containerGroups部分中将此环境变量添加到我们的ARM模板中，成功设置了{
"name": "WEBSITE_SITE_NAME",
"value": "[parameters('containerGroups_name')]"
}
属性：< / p>
WEBSITE_SITE_NAME现在AppInsights中的日志包含traces | where cloud_RoleName == "containerName"
变量中设置的值，我们可以轻松地按以下方式查询日志：
cloud_RoleInstance通过设置WEBSITE_INSTANCE_ID环境变量，这对于var data3 = [
{ group: 1, ser1: "2020-01-01", ser2: 3 },
{ group: 1, ser1: "2020-01-02", ser2: 5 },

}
drawFocus();也可能有效。
