APM .NET 服务器端监视配置

Microsoft.SystemCenter.Apm.Infrastructure.Monitoring.ApmAgent.APMConfigurationConflict.Monitor (UnitMonitor)

此监视器验证 APM 代理是否已正确处理 APM .NET 服务器端监视配置。检测到无效的配置或配置冲突时，监视器将变为警告状态。

摘要

当 APM .NET 配置无效或冲突时，实例状态将变为不正常。

原因

APM 配置基础结构基于 .NET 应用程序性能监视模板、管理包和多个文件（包含随代理一起预装的默认配置指令）中指定的设置为 APM .NET 监视代理生成配置。在此过程中，视代理问题或冲突设置而定可能会出现错误，将导致无法成功加载和使用配置。

此问题的原因可能包括：在配置过程中指定了错误的设置、在不同模板中为同一应用程序指定了冲突的设置，或者甚至是代理安装损坏且需要修复。

此类错误最常见的原因是配置冲突。例如，多个模板为相同应用程序或应用程序池指定了冲突的设置。

APM 监视应用于进程，并且只有一个配置可应用于任何特定进程。如果你在为同一进程中承载的不同应用程序配置监视，则对于进程中所有监视的应用程序，全局配置设置（例如命名空间、异常跟踪和异常处理程序）必须相同。对于 IIS，在同一应用程序池（w3wp.exe 进程）中运行的所有 Web 应用程序必须具有相同的命名空间、异常处理程序和异常跟踪配置。

除非纠正了配置冲突，否则下次应用程序池回收时将在此服务器上禁用应用程序性能监视。

解决方法

检查警报上下文和此代理上的 Operations Manager 事件日志，获取有关冲突原因的其他详细信息，以便能够解决该冲突。事件日志对于单一冲突或错误可能包含多条消息，并且将帮助你隔离在代理上导致配置冲突的应用程序组。

使用错误中提供的信息确保命名空间、异常处理程序和异常跟踪在每个指定的应用程序组之间具有相同的配置。更新应用程序组配置：

打开操作控制台。
转至创作空间。
展开管理包模板。
选择 .NET 应用程序性能监视。
选择第一个冲突的模板实例，并在“任务”窗格中单击属性。

使用属性向导，你可以调整应用程序组中冲突的设置。

APM .NET 服务器端监视配置错误或冲突

APM 代理在处理 APM .NET 服务器端监视配置时遇到错误。这可能是由代理问题导致的，或是由同一应用程序的多个模板中指定的不正确或冲突的配置或阈值导致的。
