Measures reported by InodeTest An Inode is a data structure holding information about files in a Unix
file system.
There is an inode for each file and a file is uniquely identified by
the
file system on which it resides and its inode number on that system.
Each inode contains the following information: the device where the
inode resides,
locking information, mode and type of file, the number of links to the
file,
the owner's user and group ids, the number of bytes in the file, access
and modification times,
the time the inode itself was last modified and the addresses of the
file's blocks on disk.
A Unix directory is an association between file names and inode
numbers. The operating system is configured to hold a maximum number of inode objects for each disk partition. When there
are no free inodes, then
new files cannot be created in the system.
The purpose of this test is to provide the statistics of the Inodes for
each disk partition of a system. This test works on the Unix platforms only.
The measures
made by this test are as
follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Inodes_used
|
The number of inodes that are currently in use for a disk parition
|
Number
|
|
| Inodes_free
| The number of inodes that are free for a disk partition
|
Number
|
|
| Inodes_total
| The total number of
inodes that are available for a disk partition
|
Number
|
|
| Percent_used
| The percentage of the inodes that are currently in use for a disk partition
|
Percent
|
High percentage of inode usage may lead to a problem in creating new
files/directories.
