Displays statistics for the local client. Note that the sanfs_ctl
stats command is the equivalent command on the Solaris operating system.
Parameters
Clients for AIX and Linux
- –all
- Displays all client statistics, except per-object
statistics. This parameter is the same as specifying –tm, –mc, –ls, –le, –svfs, –gio, –pager,
and –cl parameters.
- –cl
- Displays cleaner statistics.
- –cm [–host host_name –p port] –i interval
- Continuously monitors the specified statistics. The statistics are sent
as a string to the specified host_name on the specified UDP port at
every specified interval (in seconds). The minimum interval is 20 seconds.
If no host or port is specified, the statistics are sent to stdout.
- –gio
- Displays I/O statistics per global disk (GDISK), including : blocks read
and written, and the average number of bytes read and written.
- –help
- Displays a detailed description for this command.
- –ho
- Lists the states of all objects in the mcObject hash table, including
object ID, flags, and attributes
- –hos
- Displays a short list of object hash table.
- –le
- Lists mutex and latch state of all objects in the mcObject hash table,
including current holder, hold state, and waiters.
- –lo
- Lists the states of all objects in the mcObject LRU list, including object
ID, flags, and attributes.
- –los
- Displays a short list of object LRU.
- –ls
- Lists mutex and latch statistics of metadata cache objects such as mcInstance
and mcObject. Statistics include the number of attempts, wait time, and hold
time.
- –mc
- Displays metadata-cache statistics.
- –net
- Displays network statistics per metadata server with which this client
has a lease.
- –pager
- Displays pager statistics per client, including information about the
page-in and page-out activity.
- –reset
- Resets all statistics to zero. Some statistics, such as object and latch
state, cannot be reset because no counters are incremented, but data structures
are shown.
- –svfs
- Displays file-system statistics. These metrics are mount-specific and
distinguish between the different mount points. Statistics include the number
of file, inode, address space, and super operations performed.
- –tm
- Displays Transaction Manager (TM) statistics per client related to TM
data structures, including the number of messages sent and received (per
message type), the maximum lengths and average lengths of the transaction
queue, and the number of transactions, messages, and leases lost. The
statistics also include the number of transactions within certain time ranges,
or buckets, for each transaction type.
- –mountpoint mount_point
- Identifies the mount point for the file-system image for
which you want to display statistics.
- –vfsnumber vfs_number
- Identifies the virtual-file-system (VFS) number associated with the global
namespace image for which you want to display statistics. In AIX, every global
namespace image has a unique VFS number.
The stfsmount command
displays this number when it creates the global namespace image.
Clients for Windows
- –?
- Displays a detailed description for this command.
- –c
- Continuously monitors the specified statistics.
- –e
- Displays the latch state.
- –h
- Displays the object hashlist statistics.
- –i
- Displays the interval for sending statistics. This option must be used
with the –c parameter.
- –l
- Lists mutex and latch statistics of metadata cache objects.
- –m
- Displays metadata-cache statistics.
- –n
- Displays the engine statistics.
- –p
- Displays the port for sending statistics. This option must be used with
the –c parameter.
- –r
- Resets the CSM statistics
- –s
- Displays the object LRU statistics.
- –t
- Displays Transaction Manager (TM) statistics. This is the default option.
- –u
- Displays statistics in the short-output format.
- –v
- Displays file-system statistics
- drive_letter
- The drive letter mapped to SAN File System. The default letter is T.
Prerequisites
This
task must be performed only by trained service technicians.
Description
On Windows machines
running the client, the statistics parameters (?, e, h, l, m, n, r, s, t, u,
and v) are appended together. For example, to choose to display the
latch state and statistics, you would specify –el.
Note
that the sanfs_ctl stats command is the equivalent
command on the Solaris operating system.
Example
Displays statistics from a client for AIX The
following example displays transaction-manager statistics and metadata-cache
statistics for
the AIX client that is mounted on /mnt/sanfs:
stfsstat -tm -mc /mnt/sanfs
Displays statistics from a client for Windows The
following example displays statistics for the object-hash list and latch state
for
the Windows client that is mapped to
drive S:
stfsstat -he s
