\% Used Memory (SUSE Linux Enterprise Server 9)

Microsoft.Linux.SLES.9.OperatingSystem.PercentUsedMemory.Collection (Rule)

Memory\\% Used Memory 性能计数器收集规则

Knowledge Base article:

摘要

此规则收集 Memory\% Used Memory 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。

此指标显示系统当前所用总内存量在系统总内存中所占的百分比。

已用内存百分比值是用总物理内存减去可用内存（MemFree、Buffers 和 Cached），然后将结果与总物理内存值进行比较计算出来的。
