Operating System Available MegaBytes Swap Space

Microsoft.Linux.RHEL.5.OperatingSystem.AvailableMBytesSwap.Monitor (UnitMonitor)

Red Hat Enterprise Linux Server 5 Operating System Available MegaBytes Swap Space 监视器

Knowledge Base article:

摘要

该监视器检查可用交换空间的数量。如果收到监视器发出的警报，则必须采取措施以将系统恢复到操作状态。

原因

不正常状态表示可用交换空间使用率当前为高。环境可能引起此情况：

解决方法

您可查看在“状态”视图下运行“内存信息”后的可用内存。

VMStat 提供上次重新启动后平均的详细内存分析。您可在“状态”视图下运行 VMStat 任务。
