通过 REST API 创建 Azure 流量管理器 - 意外行为答案

【问题标题】：Creating Azure Traffic Manager through REST API - unexpected behaviour通过 REST API 创建 Azure 流量管理器 - 意外行为
【发布时间】：2013-12-31 22:49:36
【问题描述】：

我使用 2011-10-01 MS 版本通过其 REST API 创建了流量管理器。

我关注的资源 -

创建配置文件 - http://msdn.microsoft.com/en-us/library/windowsazure/hh758254.aspx
创建定义 - http://msdn.microsoft.com/en-us/library/windowsazure/hh758257.aspx

流量管理器已成功创建。万事如意。

但在 30 分钟后，流量管理器将进入 INACTIVE 状态，并且其所有端点都已消失。它显示没有与之关联的端点。

我不确定周围发生了什么。是 Azure 的问题吗？还是 REST API 问题？还是我创建流量管理器问题的方式。

PS - 我按照这个示例进行 REST API 调用 - http://msdn.microsoft.com/en-us/library/windowsazure/gg651127.aspx

任何帮助将不胜感激。

更新1

参数

SubscriptionID - 来自 publishsettings 的有效 GUID
证书 - 我交叉检查了本地证书存储中存在的有效证书
endpoint1 域名 - JASH13.CLOUDAPP.NET
endpoint2 域名 - JASH23.CLOUDAPP.NET

在 REST API 调用级别没有错误。一切顺利。

个人资料创建 -

更新2 TM 进入非活动状态后，我使用 REST API 检查了配置文件定义。在那里我找不到任何端点。他们不见了。

        <Definitions xmlns="http://schemas.microsoft.com/windowsazure" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    <Definition>

更新3 这种零星的行为只发生在特定的云服务和 TM 配置文件/定义中。当我创建一组新的云服务和 TM 配置文件时，一切似乎都运行良好。我对此进行了多次测试。所以唯一的问题是以下参数。

endpoint1 域名 - JASH13.CLOUDAPP.NET
endpoint2域名-JASH23.CLOUDAPP.NET
TM 域 - ramitm.trafficmanager.net
TM 配置文件名称 - ramitm

【问题讨论】：

请分享一些代码。
@GauravMantri，在上面添加了代码。
@ramiramilu 您可以分享有关您创建的 WATM 配置文件的任何信息吗？ WATM URL 或您的 cloudapp.net URL 之一会很有帮助。我可以在我们的内部日志中查找这些信息，看看发生了什么。
@kwill 当然。这些是详细信息 - WATM - ramitm.trafficmanager.net endpoint1 - jash13.cloudapp.net endpoint2 - jash23.cloudapp.net
@kwill - 一旦 TM 进入非活动状态，我查看了配置文件定义。我无法在定义中找到端点。

【解决方案1】：

这似乎是一些用于非常快速的 REST API 操作的 DNS 问题。我没能找到问题的症结所在，但我就是这样解决的。

以前我遇到过这个问题 - 创建 -> 删除 -> 重新创建

现在我这样做了 - 创建 -> 删除 -> 延迟 -> 重新创建

我认为通过引入延迟组件，我给了 Azure 足够的时间来解决所有 DNS 和基础架构并在那里更新它们。因此，在引入延迟之后，我没有遇到问题。延迟可能是 5 - 10 分钟。
