fsstat
Command
The fsstat
utility enables you to monitor file system operations by file system type and by mount point. Various options enable you to customize the output:
-
-i
-
Displays statistics about the I/O operations for mount points
-
-n
-
Displays statistics about the naming operations for mount points
The following example shows output for NFS Version 3, NFS Version 4, and the root
mount point.
% fsstat nfs3 nfs4 /
new name name attr attr lookup rddir read read write write

The following example uses the -i
option to provide statistics about the I/O operations for NFS Version 3, NFS Version 4, and the root
mount point.
% fsstat -i nfs3 nfs4 /

The following example uses the -n
option to provide statistics about the naming operations for NFS Version 3, NFS Version 4, and the root
mount point.
% fsstat -n nfs3 nfs4 /
