Free INodes Percentage

Summary

This performance rule collects performance data for the Logical Disk 'Free INodes Percentage' performance counter. The collected values are accessible in performance views and reports. Information is based on the 'df -k' and 'df -i' utility.

This metric exposes the percentage of the total inodes on the selected file system that are free.

If the percentage of free inodes on the logical disk (file system) is low, system performance may be adversely affected, and the ability to add files on the file system may be at risk until additional inodes are made available.

If the file system does not use inodes, the Percent Free Inodes value is returned as 100 percent. File system inode usage is calculated with current free and total values, which may not accurately represent true usage for file systems that dynamically allocate inodes, such as JFS.
