hrStorage objects

hrMemorySize

Type

Access

Description

KBytes

read-only

The amount of physical main memory contained by the host.

hrStorageTable

Type

Access

Description

N/A

not-accessible

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.

hrStorageEntry

Type

Access

Description

N/A

not-accessible

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

Each entry contains data for the following objects:

hrStorageIndex

hrStorageType

hrStorageDescr

hrStorageAllocationUnits

hrStorageSize

hrStorageUsed

hrStorageAllocationFailures

hrStorageIndex

Type

Access

Description

Integer

read-only

A unique value for each logical storage area contained by the host.

hrStorageType

Type

Access

Description

Object Identifier

read-only

The type of storage represented by this entry.

hrStorageDescr

Type

Access

Description

DisplayString

read-only

A description of the type and instance of the storage described by this entry.

hrStorageAllocationUnits

Type

Access

Description

Integer

read-only

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.

hrStorageSize

Type

Access

Description

Integer

read-write

The size of the storage represented by this entry, in units of hrStorageAllocationUnits.

hrStorageUsed

Type

Access

Description

Integer

read-only

The amount of the storage represented by this entry that is allocated, in units of hrStorageAllocationUnits.

hrStorageAllocationFailures

Type

Access

Description

Counter

read-only

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 Counter, that it does not have a defined initial value. However, it is recommended that this object be initialized to zero.
