Development Guide
Overview of DSNM
•
Display operational statistics about network objects (STATISTICS).
•
Define how the DSNM services layer monitors subsystem objects (UPDATE).
Use of NetCommand is discussed in the User’s Guide to DSNM Commands.
NetStatus
The NetStatus management application is a Pathway-environment application that uses
the monitoring facility of DSNM to provide a full-screen status display, which is
continuously updated. You can view the status of objects, a system, or an entire network
of systems from any point in the network. From the status display, you can use function
keys to perform a variety of operations: navigate, execute DSNM commands, query, and
control components. Frequently, you can correct an identified problem with a single
keystroke. NetStatus also allows access to the NetCommand conversational interface
directly from the block-mode Pathway screen.
The NetStatus operations environment is described in the NetStatus User’s Guide.
The Network-Management Architecture
A network-management architecture is generally divided into three layers:
•
Operations layer
•
Management services layer
•
Subsystem layer
Each layer is a set of related or parallel services having a well-defined interface with the
other layers.
The Operations Layer
The operations layer provides the interface for human operators. It may consist of
command-line and full-screen user interfaces. NonStop NET/MASTER MS,
NetCommand, and NetStatus are examples of user interfaces to DSNM.
NonStop NET/MASTER MS
NonStop NET/MASTER MS is network and system management product. It is
composed of the following major services:
•
Operator Control Services (OCS), which provides the central point of operational
control of your local Tandem system, your local NonStop NET/MASTER MS
system, and remote systems. OCS provides a command input line to enter NonStop
NET/MASTER MS commands.
•
Edit Services, which provides access to the Tandem text editor, PS Text Edit
(TEDIT). Edit Services allows NCL programmers to create and check NCL
procedures and panel description files.
