MIBs Provided with TCP/IP Services
This chapter describes how MIBs are implemented on OpenVMS. The MIBs
provided with TCP/IP Services are:
•
The Host Resources MIB, which manages operating system objects
(Section 2.1)
•
MIB II, which manages TCP/IP kernel objects (Section 2.2)
2.1 Overview of the Host Resources MIB
The Host Resources MIB defines a uniform set of objects useful for the
management of host computers. The Host Resources MIB, described by
RFC 1514, defines objects that are common across many computer system
architectures. The TCP/IP Services implementation of SNMP includes many
of these defined objects. In addition, some objects in MIB II provide host
management functionality.
2.1.1 Defining Host Resources MIB Implemented Objects
This section defines each of the implemented eSNMP objects. Table 2–1
provides a general RFC description and a specific OpenVMS description for
each implemented object.

OpenVMS Description
hrSystemUptime

host was last initialized.
Time since system boot (in hundredths of
a second).
hrSystemDate
The host’s notion of the local
date and time of day.
Date and time character string with
Coordinated Universal Time (UTC)
information if available.
hrSystemIntialLoadDevice
Index of the hrDeviceEntry
for configured initial
operating system load.
Index of SYS$SYSDEVICE in the device
table.
hrSystemIntialLoadParameters Parameters supplied to the
load device when requesting
initial operating system
configuration.
A string of boot parameters from the
console (Alpha only).
hrSystemNumUsers
Number of user sessions for
which the host is storing
state information.
Number of processes that are neither
owned by another process nor running
