NSRWATCH(8) Legato NetWorker 4.1.1 NSRWATCH(8)
NAME
nsrwatch - character-based display of NetWorker status
SYNOPSIS
nsrwatch [ -s server ] [ -p polltime ]
DESCRIPTION
The nsrwatch program displays a NetWorker server's status. The
server's name is specified by the optional -s server argument. If no
server is specified, it defaults to the same server that would be
used by a command such as recover(8) in the current directory. That
is, if the current directory is mounted from a network file server,
that file server is tried, and then the machine running the command
(if it is a NetWorker server), or the logical host name nsrhost. If
there is no NetWorker service on the selected machine, the command
issues an error message. The polling interval is specified by the
optional -p polltime argument (in seconds). The default is two
seconds.
Users can run nsrwatch from any terminal that has enough termcap(5)
capabilities for cursor positioning; it does not require any
particular window system. The nsrwatch program gets its information
via remote procedure calls to the specified server, so it can be used
from any machine that can access the server through the network.
The nsrwatch display is divided into a header and several panels: the
Server panel, the Device panel, the Sessions panel, the Messages
panel, and the Pending message panel. The panel sizes will be
adjusted depending on the size of the terminal or window being used.
The header contains the name of the server and the current time. The
Server panel provides current status of the server. The first line
of the panel is reserved for error messages. This line is usually
blank. The next line tells how long the server has been up, and the
server's release version (which may not be the same as the client's
release version). The following lines display how many saves and
recovers the current server has performed.
The Device panel displays the devices known to the current server.
For each device, the panel displays its name, the device type, the
name of the mounted volume, or (unmounted) if no volume is mounted,
and device status. The name may be followed by (J) if the device is
configured as part of a jukebox device. The Sessions panel provides
current save set information for each active session (saving,
recovering, or browsing). The Messages panel displays a history of
messages of general interest to the operator. Finally, the Pending
message panel displays messages that require operator intervention.
The nsrwatch program will run continuously until quit, stopped, or
interrupted (Control-Z or Control-C, for example). Typing the q
character will quit the program, the Control-L character will force a
screen clear and redraw, while any other character will force the
status to be updated.

The nsrwatch program checks for new devices at a slower rate than the
polling rate, so it might take up to a minute after a new device is
added before it is noticed. Restarting the program, or typing
Control-L, will notice the new device immediately. Deleted devices
may cause a ``resource does not exist'' message temporarily, but
otherwise they are noticed immediately.
The nsrwatch program will adapt to changes in the screen size, if
supported by the underlying environment. For example, if a window
terminal emulator is resized, the size of each field may change to
match the window. If the window is too small, all the devices,
sessions, messages, etc. might not be displayed. For best results,
use a window of at least 30 lines.
