Total Processor \% DPC Time (SUSE Linux Enterprise Server 12)

Microsoft.Linux.SLES.12.OperatingSystem.TotalPercentDPCTime.Collection (Rule)

收集 Processor\\% DPC Time 性能计数器

Knowledge Base article:

摘要

此规则收集 Processor\% DPC Time (_Total) 性能计数器的性能数据。在性能视图和报表中可以访问收集的值。

此指标显示所有处理器在接收和服务延缓过程调用 (DPC) 上花费的时间的百分比。DPC 是运行优先级低于标准中断的中断。DPC 时间百分比是特权时间百分比的组成部分,因为 DPC 在特权模式下执行。如果 DPC 时间百分比 (%) 持续较高,则可能存在处理器瓶颈或者与应用程序或硬件相关的问题,该问题可能导致总体系统性能显著降低。

代理返回的值是按 1 分钟间隔查询的最近 5 个值的移动平均值。
