Host Resources MIB
Status of this Memo
This RFCspecifies 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" for the standardization state and status
of this protocol. Distribution of this memo is unlimited.
Abstract
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 Network Management Framework
The Internet-standard Network Management Framework consists of three
components. They are:
STD 16, RFC1155 [1] which defines the SMI, the mechanisms used
for describing and naming objects for the purpose of management.
STD 16, RFC1212 [2] defines a more concise description mechanism,
which is wholly consistent with the SMI.
STD 17, RFC1213 [3] which defines MIB-II, the core set of managed
objects for the Internet suite of protocols.
STD 15, RFC1157 [4] which defines the SNMP, the protocol used for
network Access to managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Within a given MIB module,
objects are defined using STD 16, RFC1212"s OBJECT-TYPE macro. At a
minimum, each object has a name, a syntax, an access-level, and an
implementation-status.
The name is an object identifier, an administratively assigned name,
which specifies an object type. The object type together with an
object instance serves to uniquely identify a specific instantiation
of the object. For human convenience, we often use a textual string,
termed the object descriptor, to also refer to the object type.
The syntax of an object type defines the abstract data structure
corresponding to that object type. The ASN.1[5] language is used for
this purpose. However, RFC1155 purposely restricts the ASN.1
constructs which may be used. These restrictions are explicitly made
for simplicity.
The access-level of an object type defines whether it makes "protocol
sense" to read and/or write the value of an instance of the object
type. (This access-level is independent of any administrative
authorization policy.)
The implementation-status of an object type indicates whether the
object is mandatory, optional, obsolete, or deprecated.
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 MIB-II [3] which also provide host
management functionality. Implementation of the System and Interfaces
groups is mandatory for implementors of the Host Resources MIB.

-- textual conventions
-- a truth value
Boolean ::= INTEGER { true(1), false(2) }
-- memory size, expressed in units of 1024bytes
KBytes ::= INTEGER (0..2147483647)
-- 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.
ProductID ::= OBJECT IDENTIFIER
-- unknownProduct will be used for any unknown ProductID
-- unknownProduct OBJECT IDENTIFIER ::= { 0 0 }
-- 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)

-- Note that if only local time is known, then
-- timezone information (fields 8-10) is not present.
InternationalDisplayString ::= OCTET STRING
-- This data type is used to model textual information in some
-- character set. A network management station 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

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."

the hrDeviceStatus would not otherwise be
unknown(1) or testing(4), the hrDeviceStatus shall
correspond to the worst state of those indicated,
where down(5) is worse than warning(3) which is
worse than running(2).
Bits are numbered starting with the most
significant bit of the first byte being bit 0, the
least significant bit of the first byte being bit
7, the most significant bit of the second byte
being bit 8, and so on. A one bit encodes that
the condition was detected, while a zero bit
encodes that the condition was not detected.
