HOST-RESOURCES-MIB device MIB details by RFC

HOST-RESOURCES-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

   DESCRIPTION
       "This MIB is for use in 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."

   REVISION "200003060000Z"        -- 6 March 2000
   DESCRIPTION
       "Clarifications and bug fixes based on implementation
       experience.  This revision was also reformatted in the SMIv2
       format. The revisions made were:

       New RFC document standards:
          Added Copyright notice, updated introduction to SNMP
          Framework, updated references section, added reference to
          RFC 2119, and added a meaningful Security Considerations
          section.

       New IANA considerations section for registration of new types

       Conversion to new SMIv2 syntax for the following types and
       macros:
           Counter32, Integer32, Gauge32, MODULE-IDENTITY,
           OBJECT-TYPE, TEXTUAL-CONVENTION, OBJECT-IDENTITY,
           MODULE-COMPLIANCE, OBJECT-GROUP

       Used new Textual Conventions:
           TruthValue, DateAndTime, AutonomousType,
           InterfaceIndexOrZero

       Fixed typo in hrPrinterStatus.

       Added missing error bits to hrPrinterDetectedErrorState and
       clarified confusion resulting from suggested mappings to
       hrPrinterStatus.


       Clarified that size of objects of type
       InternationalDisplayString is number of octets, not number
       of encoded symbols.

       Clarified the use of the following objects based on
       implementation experience:
           hrSystemInitialLoadDevice, hrSystemInitialLoadParameters,
           hrMemorySize, hrStorageSize, hrStorageAllocationFailures,
           hrDeviceErrors, hrProcessorLoad, hrNetworkIfIndex,
           hrDiskStorageCapacity, hrSWRunStatus, hrSWRunPerfCPU,
           and hrSWInstalledDate.

       Clarified implementation technique for hrSWInstalledTable.

       Used new AUGMENTS clause for hrSWRunPerfTable.

       Added Internationalization Considerations section.

This revision published as RFC2790."

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

        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
        specified for an object of this type, the size refers

    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
