NAME
vxfsstat - display VxFS file system statistics
SYNOPSIS
vxfsstat [-aCgsvxz][-e
columns][-c sample_count][-t seconds] mount_point
vxfsstat [-abi][-c
sample_count][-t seconds] mount_point
vxfsstat [-w outfile][
-c sample_count][-t seconds] mount_point
vxfsstat -r infile [-aCgsvxz
][-e columns]
DESCRIPTION
vxfsstat is a statistical reporter to aid in performance tuning and determining performance anomalies.
vxfsstat gathers buffer cache, inode cache, DNLC (directory name lookup cache), per-CPU statistics,
per-file system statistics for local and cluster mounted file system, and global cluster file system counters.
The mount_point specifies any VxFS file system mount point. mount_point is used as an ioctl entry point to
access the statistics maintained by the VxFS kernel.
Options
vxfsstat recognizes the following options:
-a Displays absolute values.
-b Displays buffer cache statistics.
-c sample_count
Specifies the number of samples to take.
-C Displays per-CPU statistics.
-e columns Selects the number of column entries to display per line of output. The default is two
columns. -e does not affect all output formats.
-g Displays cluster file system global statistics. Not valid on non-cluster (local) mounted file sys-
tems.
-i Displays inode cache and DNLC statistics. -i is the default output format.
-r infile Replays output from the specified file infile. You can create output files using the
-w option.
-s Displays per-file system statistics for cluster file systems. Not valid on non-cluster (local)
mounted file systems.
-t seconds Specifies the duration of the sampling interval in seconds.
-v Displays VxFS shared counters and statistics.
-w outfile Appends output to the specified file outfile. vxfsstat
can be invoked multiple times with
the same file to collect multiple samples. The
-w option can only be used with the
-c, and
-t options.
-x Displays per-file system VxFS statistics.
-z Displays only non-zero values.
Operands
vxfsstat recognizes the following operand:
mount_point Name of any VxFS file system mount point. mount_point is used as an ioctl entry point to
access the statistics maintained by the VxFS kernel.
Notes
The vxfsstat command was introduced to provide a diagnostic and tuning tool for knowledgeable VxFS
file system users. The command is still under development and may undergo significant additions and
changes. There is a strong possibility that functionality introduced and modified in future versions will not
be completely backward compatible. Take this into account when you begin using this command and incor-
porating it into scripts.
