Network File System protocol (NFS) is often used to share file systems between servers and clients. Often, if an NFS file system fails, the directories mapped to the NFS file system will be unavailable. Accesses to these directories/files will take a long time and ultimately fail. This could potentially result in application failures and outages. Hence, administrators need the capability to detect when an NFS file system is unavailable or is running out of space. The NfsMountTest provides administrators with this capability.

This test should be executed on a system that is an NFS client - i.e., is mounting directories from remote servers. This test auto-discovers all NFS-mounted directories and in real-time monitors the availability and space usage of each of these directories. This test is supported only on Unix platforms (i.e., not on Windows). Only agent-based monitoring is supported. One set of records for each NFS mounted file system.

Measurement	Description	Measurement Unit	Interpretation
Availability	This measure indicates whether the NFS was able to accessible or not.	Percent	A value 100 indicates a mounted NFS was accessible. A value 0 indicates a mounted NFS was not accessible.
Total_capacity	The total capacity of the mounted system disk partition	MB
Used_space	The amount of space used in a mounted system disk partition	MB
Free_space	The current free space available for a diskpartition of a mounted system	MB
Percent_usage	The percentage of space usage on a mounted system disk partition	Percent	A value close to 100% can indicate a potential problem situation where applications executing on the system may not be able to write data to the disk partition(s) with very high usage.
