\% Available Memory (Red Hat Enterprise Linux Server 5)

Microsoft.Linux.RHEL.5.OperatingSystem.PercentAvailableMemory.Collection (Rule)

Memory\\% Available Memory 性能计数器收集规则

Knowledge Base article:

摘要

此规则收集 Memory\% Available 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。

此指标显示可用总内存量在系统总内存中所占的百分比。

可用内存的百分比值是通过比较操作系统报告的可用内存（MemFree、Buffers 和 Cached）和总物理内存值计算出来的。
