收集 .NET Apps/Avg.Request Time (sec)

Microsoft.SystemCenter.Apm.ApplicationInstance.CollectAvgDurationTimeSeconds (Rule)

.NET Apps/Avg.Request Time (sec) 计数器提供应用程序响应请求所花费的平均时间

摘要

此规则为应用程序收集 .NET Apps Avg.Request Time 性能计数器。

此计数器记录应用程序处理请求花费的平均时间（以秒为单位）。每个请求的计时从请求到达应用程序时开始，并在请求成功完成或在代码中的某处失败时停止。这些时间的和由受监视的请求的总数加以平均。如果此时间始终超过 10000 毫秒，则表示存在着应加以调查的瓶颈。

仅在启用应用程序性能监视时，此计数器才可用。

服务器问题或查询结构和复杂性的问题可能会导致数据库调用时间过长。文件服务器问题可能会导致文件 I/O 时间很长。Web 服务或它驻留的服务器关闭，或者 Web 服务代码中出现问题，都可能会导致 Web 服务的性能问题。复杂或低效的代码可能会导致应用程序的内部执行时间很长。
