System Administration Commands                         ndmpstat(1M)

NAME
     ndmpstat - show NDMP backup progress statistics

SYNOPSIS
     ndmpstat [interval [count]]

DESCRIPTION
     ndmpstat reports NDMP statistics  regarding  NDMP worker
     threads, disk IO, tape IO, files operation, performance
     and backup activity.

     ndmpstat reports the aggregate numbers for all tapes and disks.

OPERANDS
     The following operands are supported:

     count     Specifies the number of times that the  statistics
               are  repeated.

     interval  Specifies the last number of  seconds  over  which
               ndmpstat summarizes activity. This number of seconds
               repeats forever.

EXAMPLES
     Example 1 Using ndmpstat

     The following command displays a summary of what NDMP daemon
     is doing every five seconds.

     The fields of ndmpstat's display are

     wthr    Report the number of worker threads in each  of  the
             four following states:

             r  the number of worker threads running

             w  the number of blocked  worker  threads  that  are
                waiting for resources I/O, paging, and so forth


     ops     Report the number of backup/restore operations currently
             running:

             bk the number of backups operations currently running

             rs the number of restores operations currently running


     file    Report on usage of filesystem 

             rd  the number of file read operations

             wr  the number of file write operations


     disk    Report the number of  disk  operations  per  interval.

             rd  the number of disk blocks being read

             wr  the number of disk blocks being written


     tape    Report the number of  tape  operations  per  interval.

             rd  the number of tape blocks being read

             wr  the number of tape blocks being written


     bytes   the number of bytes transfered in general. This is the
             aggregate value of both tapes and disk. The number is
             in kilobytes.

             rd  the number of kilobytes being read

             wr  the number of kilobytes being written

 
     perf    This is a rough estimate of performance of the backup/restore
             operation in megabytes per second.

             bk  backup performance

             rs  restore performance

     prcnt   Give the breakdown of percentage usage of worker time.
 
             dsk  disk IO time
 
             tpe  tape IO time
 
             idl  idle time
