SYNTAX OBJECT IDENTIFIER
-- unknownProduct will be used for any unknown ProductID
-- unknownProduct OBJECT IDENTIFIER ::= { 0 0 }
InternationalDisplayString ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"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 ASCII. When a size clause is
specified for an object of this type, the size refers
to the length in octets, not the number of symbols."

hrSystemUptime OBJECT-TYPE
SYNTAX TimeTicks
MAX-ACCESS read-only
STATUS current
DESCRIPTION
Waldbusser & Grillo Standards Track [Page 7]
RFC 2790 Host Resources MIB March 2000
"The amount of time since this host was last
initialized. Note that this is different from
sysUpTime in the SNMPv2-MIB [RFC1907] because
sysUpTime is the uptime of the network management
portion of the system."

hrSystemDate OBJECT-TYPE
SYNTAX DateAndTime
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The host's notion of the local date and time of day."
::= { hrSystem 2 }
hrSystemInitialLoadDevice OBJECT-TYPE
SYNTAX Integer32 (1..2147483647)
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The index of the hrDeviceEntry for the device from
which this host is configured to load its initial
operating system configuration (i.e., which operating
system code and/or boot parameters).
Note that writing to this object just changes the
configuration that will be used the next time the
operating system is loaded and does not actually cause
the reload to occur."
::= { hrSystem 3 }
hrSystemInitialLoadParameters OBJECT-TYPE
SYNTAX InternationalDisplayString (SIZE (0..128))
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"This object contains the parameters (e.g. a pathname
and parameter) supplied to the load device when
requesting the initial operating system configuration
from that device.
Note that writing to this object just changes the
configuration that will be used the next time the
operating system is loaded and does not actually cause
the reload to occur."

RFC 2790 Host Resources MIB March 2000
SYNTAX Gauge32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of user sessions for which this host is
storing state information. A session is a collection
of processes requiring a single act of user
authentication and possibly subject to collective job
control."
::= { hrSystem 5 }
hrSystemProcesses OBJECT-TYPE
SYNTAX Gauge32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of process contexts currently loaded or
running on this system."

hrSystemMaxProcesses OBJECT-TYPE
SYNTAX Integer32 (0..2147483647)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The maximum number of process contexts this system
can support. If there is no fixed maximum, the value
should be zero. On systems that have a fixed maximum,
this object can help diagnose failures that occur when
this maximum is reached."

UNITS "KBytes"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The amount of physical read-write main memory,
typically RAM, contained by the host."
::= { hrStorage 2 }
Waldbusser & Grillo Standards Track [Page 9]
RFC 2790 Host Resources MIB March 2000
hrStorageTable OBJECT-TYPE
SYNTAX SEQUENCE OF HrStorageEntry
MAX-ACCESS not-accessible
STATUS current
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."
::= { hrStorage 3 }
hrStorageEntry OBJECT-TYPE
SYNTAX HrStorageEntry
MAX-ACCESS not-accessible

DESCRIPTION
"A (conceptual) entry for one logical storage area on
the host. As an example, an instance of the
hrStorageType object might be named hrStorageType.3"

::= { hrStorageEntry 3 }
hrStorageAllocationUnits OBJECT-TYPE
SYNTAX Integer32 (1..2147483647)
UNITS "Bytes"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The size, in bytes, of the data objects allocated
from this pool. If this entry is monitoring sectors,
blocks, buffers, or packets, for example, this number
will commonly be greater than one. Otherwise this
number will typically be one."
::= { hrStorageEntry 4 }
hrStorageSize OBJECT-TYPE
Waldbusser & Grillo Standards Track [Page 11]
RFC 2790 Host Resources MIB March 2000
SYNTAX Integer32 (0..2147483647)
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The size of the storage represented by this entry, in
units of hrStorageAllocationUnits. This object is
writable to allow remote configuration of the size of
the storage area in those cases where such an
operation makes sense and is possible on the
underlying system. For example, the amount of main
memory allocated to a buffer pool might be modified or
the amount of disk space allocated to virtual memory
might be modified."
::= { hrStorageEntry 5 }
hrStorageUsed OBJECT-TYPE
SYNTAX Integer32 (0..2147483647)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The amount of the storage represented by this entry
that is allocated, in units of
hrStorageAllocationUnits."
::= { hrStorageEntry 6 }
hrStorageAllocationFailures OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of requests for storage represented by
this entry that could not be honored due to not enough
storage. It should be noted that as this object has a
SYNTAX of Counter32, that it does not have a defined
initial value. However, it is recommended that this
object be initialized to zero, even though management
stations must not depend on such an initialization."
