\% Free Inodes (SUSE Linux Enterprise Server 9)

Microsoft.Linux.SLES.9.LogicalDisk.PercentFreeInodes.Collection (Rule)

Logical Disk\\% Free Inodes 性能计数器收集规则

Knowledge Base article:

摘要

此规则收集 Logical Disk\% Free Inodes 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。

此指标显示所选文件系统上可用的总 Inode 所占的百分比。

如果文件系统不使用 Inode，则返回的 Percent Free Inodes 值为 100%。文件系统 Inode 使用率是使用当前的可用值和总值计算的，这可能未准确表示动态分配 Inode 的文件系统（例如 JFS）的真实使用率。
