Host Resources MIB
Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements.; Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol.; Distribution of this memo is unlimited.

Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
This memo obsoletes RFC1514, the "Host Resources MIB". This memo
extends that specification by clarifying changes based on
implementation and deployment eXPerience and documenting the Host
Resources MIB in SMIv2 format while remaining semantically identical
to the existing SMIv1-based MIB.
This memo defines a MIB for use with managing host systems.; The term
"host" is construed to mean any computer that communicates with other
similar computers attached to the internet and that is directly used
by one or more human beings. Although this MIB does not necessarily
apply to devices whose primary function is communications services
(e.g., terminal servers, routers, bridges, monitoring equipment),
such relevance is not explicitly precluded.; This MIB instruments
attributes common to all internet hosts including, for example, both
personal computers and systems that run variants of Unix.

1.; The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
oAn overall architecture, described in RFC2571 [RFC2571].
oMechanisms for describing and naming objects and events for the
;;;;purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in STD
16, RFC1155 [RFC1155], STD 16, RFC1212 [RFC1212] and RFC1215
[RFC1215]. The second version, called SMIv2, is described in STD
58, RFC2578 [RFC2578], RFC2579 [RFC2579] and RFC2580
[RFC2580].
oMessage protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in STD 15, RFC1157 [RFC1157]. A second version of the
SNMP message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in RFC1901 [RFC1901]
and RFC1906 [RFC1906]. The third version of the message protocol
is called SNMPv3 and described in RFC1906 [RFC1906], RFC2572
[RFC2572] and RFC2574 [RFC2574].
oProtocol operations for Accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC1157 [RFC1157]. A second set of protocol
operations and associated PDU formats is described in RFC1905
[RFC1905].
oA set of fundamental applications described in RFC2573 [RFC2573]
and the view-based access control mechanism described in RFC2575
[RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC2570 [RFC2570].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB.; Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process.; However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
2.; Host Resources MIB
The Host Resources MIB defines a uniform set of objects useful for
the management of host computers.; Host computers are independent of
the operating system, network services, or any software application.
The Host Resources MIB defines objects which are common across many
computer system architectures.
In addition, there are objects in the SNMPv2-MIB [RFC1907] and IF-MIB
[RFC2233] which also provide host management functionality.
Implementation of the System and Interfaces groups is mandatory for
implementors of the Host Resources MIB.
The key Words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED","MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
3.; IANA Considerations
This MIB contains type definitions for storage types, device types,
and file system types for use as values for the hrStorageType,
hrDeviceType, and hrFSType objects, respectively. As new computing
technologies are developed, new types need to be registered for these
technologies. The IANA (Internet Assigned Numbers Authority) is
designated as the registration authority for new registrations beyond
those published in this document. The IANA will maintain the HOST-
RESOURCES-TYPES module as new registrations are added and publish new
versions of this module.
Given the large number of such technologies and potential confusion
in naming of these technologies (such as a technology known by two
names or a name and an acronym), there is a real danger that more
than one registration might be created for what is essentially the
same technology. In order to ensure that future type registrations
are performed correctly, applications for new types will be reviewed
by a Designated Expert appointed by the IESG.

ProductID ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This textual convention is intended to identify the
manufacturer, model, and version of a specific
hardware or software product.; It is suggested that
these OBJECT IDENTIFIERs are allocated such that all
products from a particular manufacturer are registered
under a suBTree distinct to that manufacturer.; In
addition, all versions of a product should be
registered under a subtree distinct to that product.
With this strategy, a management station may uniquely
determine the manufacturer and/or model of a product
whose productID is unknown to the management station.
Objects of this type may be useful for inventory
purposes or for automatically detecting
incompatibilities or version mismatches between
various hardware and software components on a system.
For example, the product ID for the ACME 4860 66MHz
clock doubled processor might be:
enterprises.acme.acmeProcessors.a4860DX2.MHz66
A software product might be registered as:
enterprises.acme.acmeOperatingSystems.acmeDOS.six(6).one(1)

DESCRIPTION
"This data type is used to model textual information

should use a local algorithm to determine which
character set is in use and how it should be
displayed.; Note that this character set may be
encoded with more than one octet per symbol, but will
most often be NVT ASCII. When a size clause is

to the length in octets, not the number of symbols."

DESCRIPTION
"The (conceptual) table of logical storage areas on
the host.
An entry shall be placed in the storage table for each
logical area of storage that is allocated and has
fixed resource limits.; The amount of storage
represented in an entity is the amount actually usable
by the requesting entity, and excludes loss due to
formatting or file system reference information.
These entries are associated with logical storage
areas, as might be seen by an application, rather than
physical storage entities which are typically seen by
an operating system.; Storage such as tapes and
floppies without file systems on them are typically
not allocated in chunks by the operating system to
requesting applications, and therefore shouldn't
appear in this table.; Examples of valid storage for
this table include disk partitions, file systems, ram
(for some architectures this is further segmented into
regular memory, extended memory, and so on), backing
store for virtual memory (`swap space').
This table is intended to be a useful diagnostic for
`out of memory' and `out of buffers' types of
failures.; In addition, it can be a useful performance
monitoring tool for tracking memory, disk, or buffer
usage."
