What Is in This Section This section introduces the Distributed Systems Network Management (DSNM)
product and its command set. Commands in the DSNM command set can be issued
from the following management applications:
NetCommand
NetStatus
NonStop NET/MASTER Management Services (MS)
See Section 6, “NetCommand Interface,” for special considerations when issuing the
commands from NetCommand; Section 7, “NonStop NET/MASTER MS Interface,”
when issuing the commands from NonStop NET/MASTER MS; and the NetStatus
User’s Guide, when issuing the commands from NetStatus.
Details on the syntax of individual DSNM commands are given in Section 2, “DSNM
Commands.”
Basic Information
About DSNM
DSNM is one of three products that make up the Distributed Systems Management
Solutions (DSMS) product package. DSNM is a management service layer between
management applications—for example, NetCommand and NetStatus, or NonStop
NET/MASTER MS—and the individual management facilities for Tandem
subsystems and user applications.
DSNM processes and passes information between management applications and the
subsystem resources that the applications manage. It provides services in three
functional areas:
Control services that allow programmed or human operators to exercise control
over objects.
Information retrieval services that return status, statistical, and configuration
information about objects on request.
Monitoring services that continuously and automatically report state changes of
objects throughout the network. DSNM maintains an object database where
definitions of monitored subsystems and their objects reside.
Within each functional area, DSNM provides:
A common set of commands with the same syntax and semantics across all
supported subsystems. The DSNM command set provides transparent access to a
variety of subsystems, shielding the operator from disparate command
interpreters and syntaxes. The DSNM command set is universal in the sense that
a single command can apply to all the subsystems DSNM manages.
Standard responses to operator commands from different subsystems. This
feature complements the concept of a universal command set. As the DSNM
command set insulates operators from disparate command sets, the response
translation function aims at translating functionally equivalent command
responses into a response common to all subsystems.
