xii 119728—SNMP Subagent Programmer’s Guide
About This Manual
•
Write Management Information Base (MIB) definitions describing resources to be
managed.
•
Compile MIB definitions using GDMOC, the MIB compiler provided with the
Toolkit, to create a subagent header file containing run-time access logic.
•
Write C program modules that use Toolkit header files and run-time library
functions for handling SNMP operations.
•
Compile header files and subagent logic, then bind the compiler output with the
Toolkit’s run-time library to create executable subagents.
Organization
This manual is organized into five sections:
•
Section 1, “Introduction to Subagent Programming,” describes how the Toolkit
components fit into the subagent development and usage cycles.
•
Section 2, “Programming Tutorials,” describes the eight sample subagents provided
with the Toolkit.
•
Section 3, “Writing and Compiling MIBs,” presents the syntax conventions for
encoding MIBs and running GDMOC, the MIB compiler.
•
Section 4, “Writing Subagent Logic,” describes the elements to encode in C program
logic to implement SNMP instrumentation.
•
Section 5, “Creating Executable Subagents,” provides instructions for compiling,
binding, and accelerating subagents.
Related Reading
This manual has two companion manuals:
•
SNMP Configuration and Management Manual, which describes how to install and
configure the NonStop agent and interpret information generated by subagents
Tandem provides. This manual also contains a glossary that provides definitions to
orient those new to either SNMP or NonStop systems.
•
SCF Reference Manual for the SNMP Agent, which describes how to use the
Subsystem Control Facility (SCF) to configure the NonStop agent
The following additional Tandem manuals may be useful while you are writing and
building subagents from C language modules:
•
C Programmer’s Guide and Guardian C Library Calls Reference Manual, which
document the NonStop C language, compiler, and run-time library
•
Binder Manual, which documents the Binder utility, used to link object files into
executable files
•
Accelerator Manual, which documents the Accelerator utility available for
optimizing applications that run on TNS/R systems
