Used Space Percentage

Summary

This rule collects performance data for the Logical Disk\% Used Space performance counter. The collected values are accessible in performance views and reports.

This metric exposes the percentage of the total usable space on the selected logical disk (file system) that is currently allocated.

The file system space reserved for the root user is included in the calculated used space. File system space usage is calculated with current free and total values, which may not accurately represent true usage for file systems that dynamically allocate space, such as ZFS.
