NAME

SYNOPSIS

9       ndmpstat  [tapes] [interval [count]]
10
11

DESCRIPTION

13       The  ndmpstat  utility  reports Network Data Management Protocol (NDMP)
14       statistics, among which are  NDMP worker threads,  disk  IO,  tape  IO,
15       files operation, performance, and backup activity.
16
17
18       ndmpstat  reports  the aggregate statistics for all tapes and disks. In
19       order to obtain statistics for specific tape devices, the  tape  device
20       name should be passed as argument to the utility.
21
22
23       When  invoked,  ndmpstat  begins its display with a one-line summary of
24       the NDMP daemon activity since the NDMP service was invoked.
25

OPERANDS

159       The following operands are supported:
160
161       count       Specifies the number of times that the  statistics  display
162                   is repeated.
163
164
165       tape        Specifies  which tapes are to be given priority in the out‐
166                   put. A command line is limited to a maximum  of  four  tape
167                   devices.  A  common  tape name is /dev/rmt/n, where n is an
168                   integer.
169
170
171       interval    Specifies the number of seconds over which ndmpstat  summa‐
172                   rizes  activity.  The  specified interval remains in effect
173                   till the command is terminated.
