What Is HOST-RESOURCES-MIB?

HOST-RESOURCES-MIB is a vendor-neutral IETF standards MIB (RFC 2790) that defines managed objects for the resources and operational characteristics of general-purpose host computer systems, i.e., any internet-connected computer directly used by a person, though it is not strictly precluded from applying to other device types. It exposes broad categories of data including system-level attributes (uptime, date, boot device/parameters, number of logged-in users), running process information, installed software inventory, and storage/memory resources. It is one of the most fundamental hardware/software status MIBs in existence: hrSystemUptime tracks how long the system has been running, hrSystemProcesses/hrSystemMaxProcesses reveal process-table load, hrMemorySize and hrStorageTable expose memory and disk/filesystem capacity and usage, and hrSystemNumUsers shows active user sessions, together giving a full picture of host health and load. It typically works alongside SNMPv2-MIB (for sysUpTime/system group) and is often deployed together with vendor-specific extensions for deeper platform detail. It is deployed extremely broadly, on servers, workstations, and many network appliances that embed a host-like OS, wherever generic cross-platform system monitoring via SNMP is needed. As the canonical host resources mib, it remains the go-to standard whenever vendor-neutral, cross-platform system monitoring is required.

IPNetwork Monitor allows you to monitor SNMP objects defined in HOST-RESOURCES-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

What Can Be Monitored

system uptime
system date/time
number of logged-in users
running process count vs. maximum
installed/running software
storage (disk) utilization per volume
total physical memory size

Supported Devices

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
general-purpose host computers (servers, workstations)
network appliances with an embedded host-like OS

Monitoring Examples

An operator would poll hrSystemUptime and hrSystemNumUsers to check how long a server has been running and how many users are logged in, and watch hrSystemProcesses against hrSystemMaxProcesses to detect an approaching process-table exhaustion. Walking hrStorageTable/hrStorageEntry (indexed by hrStorageIndex) reveals per-volume storage utilization, so a disk partition nearing capacity would show up as a shrinking free-space ratio in that table. hrMemorySize gives total physical memory, useful as a baseline when correlating with process or storage growth trends, while hrSystemInitialLoadDevice/hrSystemInitialLoadParameters record what device and parameters the system last booted from.

OIDs

OID symbolic	OID numeric	Type	Access	Description
host	1.3.6.1.2.1.25
hostResourcesMibModule	1.3.6.1.2.1.25.7.1			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.
hrDevice	1.3.6.1.2.1.25.3
STR hrDeviceDescr	1.3.6.1.2.1.25.3.2.1.3	DisplayString	read-only	A textual description of this device, including the device's manufacturer and revision, and optionally, its serial number.
hrDeviceEntry	1.3.6.1.2.1.25.3.2.1		not-accessible	A (conceptual) entry for one device contained by the host. As an example, an instance of the hrDeviceType object might be named hrDeviceType.3
C32 hrDeviceErrors	1.3.6.1.2.1.25.3.2.1.6	Counter32	read-only	The number of errors detected on this device. 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.
hrDeviceGroup	1.3.6.1.2.1.25.7.3.3			The Host Resources Device Group.
PRO hrDeviceID	1.3.6.1.2.1.25.3.2.1.4	ProductID	read-only	The product ID for this device.

A value unknown(1) indicates that the current state of the device is unknown. running(2) indicates that the device is up and running and that no unusual error conditions are known. The warning(3) state indicates that agent has been informed of an unusual error condition by the operational software (e.g., a disk device driver) but that the device is still 'operational'. An example would be a high number of soft errors on a disk. A value of testing(4), indicates that the device is not available for use because it is in the testing state. The state of down(5) is used only when the agent has been informed that the device is not available for any use.

NUM hrNetworkIfIndex	1.3.6.1.2.1.25.3.4.1.1	InterfaceIndexOrZero	read-only	The value of ifIndex which corresponds to this network device. If this device is not represented in the ifTable, then this value shall be zero.
hrNetworkTable	1.3.6.1.2.1.25.3.4		not-accessible	The (conceptual) table of network devices contained by the host. Note that this table is potentially sparse: a (conceptual) entry exists only if the correspondent value of the hrDeviceType object is `hrDeviceNetwork'.
hrPartitionEntry	1.3.6.1.2.1.25.3.7.1		not-accessible	A (conceptual) entry for one partition. The hrDeviceIndex in the index represents the entry in the hrDeviceTable that corresponds to the hrPartitionEntry.

OCT hrPrinterDetectedErrorState	1.3.6.1.2.1.25.3.5.1.2	OCTET STRING	read-only	This object represents any error conditions detected by the printer. The error conditions are encoded as bits in an octet string, with the following definitions: Condition Bit # lowPaper 0 noPaper 1 lowToner 2 noToner 3 doorOpen 4 jammed 5 offline 6 serviceRequested 7 inputTrayMissing 8 outputTrayMissing 9 markerSupplyMissing 10 outputNearFull 11 outputFull 12 inputTrayEmpty 13 overduePreventMaint 14 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. This object is useful for alerting an operator to specific warning or error conditions that may occur, especially those requiring human intervention.
hrPrinterEntry	1.3.6.1.2.1.25.3.5.1		not-accessible	A (conceptual) entry for one printer local to the host. The hrDeviceIndex in the index represents the entry in the hrDeviceTable that corresponds to the hrPrinterEntry.

hrPrinterTable	1.3.6.1.2.1.25.3.5		not-accessible	The (conceptual) table of printers local to the host. Note that this table is potentially sparse: a (conceptual) entry exists only if the correspondent value of the hrDeviceType object is `hrDevicePrinter'.
hrProcessorEntry	1.3.6.1.2.1.25.3.3.1		not-accessible	A (conceptual) entry for one processor contained by the host. The hrDeviceIndex in the index represents the entry in the hrDeviceTable that corresponds to the hrProcessorEntry. As an example of how objects in this table are named, an instance of the hrProcessorFrwID object might be named hrProcessorFrwID.3
PRO hrProcessorFrwID	1.3.6.1.2.1.25.3.3.1.1	ProductID	read-only	The product ID of the firmware associated with the processor.
I32 hrProcessorLoad	1.3.6.1.2.1.25.3.3.1.2	Integer32	read-only	The average, over the last minute, of the percentage of time that this processor was not idle. Implementations may approximate this one minute smoothing period if necessary.
hrProcessorTable	1.3.6.1.2.1.25.3.3		not-accessible	The (conceptual) table of processors contained by the host. Note that this table is potentially sparse: a (conceptual) entry exists only if the correspondent value of the hrDeviceType object is `hrDeviceProcessor'.
hrStorage	1.3.6.1.2.1.25.2
C32 hrStorageAllocationFailures	1.3.6.1.2.1.25.2.3.1.7	Counter32	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 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.
I32 hrStorageAllocationUnits	1.3.6.1.2.1.25.2.3.1.4	Integer32	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.
STR hrStorageDescr	1.3.6.1.2.1.25.2.3.1.3	DisplayString	read-only	A description of the type and instance of the storage described by this entry.
hrStorageEntry	1.3.6.1.2.1.25.2.3.1		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
hrStorageGroup	1.3.6.1.2.1.25.7.3.2			The Host Resources Storage Group.
I32 hrStorageIndex	1.3.6.1.2.1.25.2.3.1.1	Integer32	read-only	A unique value for each logical storage area contained by the host.
I32 hrStorageSize	1.3.6.1.2.1.25.2.3.1.5	Integer32	read-write	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.
hrStorageTable	1.3.6.1.2.1.25.2.3		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.
OID hrStorageType	1.3.6.1.2.1.25.2.3.1.2	AutonomousType	read-only	The type of storage represented by this entry.
hrStorageTypes	1.3.6.1.2.1.25.2.1

DAT hrSWInstalledDate	1.3.6.1.2.1.25.6.3.1.5	DateAndTime	read-only	The last-modification date of this application as it would appear in a directory listing. If this information is not known, then this variable shall have the value corresponding to January 1, year 0000, 00:00:00.0, which is encoded as (hex)'00 00 01 01 00 00 00 00'.
hrSWInstalledEntry	1.3.6.1.2.1.25.6.3.1		not-accessible	A (conceptual) entry for a piece of software installed on this host. As an example of how objects in this table are named, an instance of the hrSWInstalledName object might be named hrSWInstalledName.96

I32 hrSWInstalledIndex	1.3.6.1.2.1.25.6.3.1.1	Integer32	read-only	A unique value for each piece of software installed on the host. This value shall be in the range from 1 to the number of pieces of software installed on the host.
TIK hrSWInstalledLastChange	1.3.6.1.2.1.25.6.1	TimeTicks	read-only	The value of sysUpTime when an entry in the hrSWInstalledTable was last added, renamed, or deleted. Because this table is likely to contain many entries, polling of this object allows a management station to determine when re-downloading of the table might be useful.
TIK hrSWInstalledLastUpdateTime	1.3.6.1.2.1.25.6.2	TimeTicks	read-only	The value of sysUpTime when the hrSWInstalledTable was last completely updated. Because caching of this data will be a popular implementation strategy, retrieval of this object allows a management station to obtain a guarantee that no data in this table is older than the indicated time.
NUM hrSWInstalledName	1.3.6.1.2.1.25.6.3.1.2	InternationalDisplayString	read-only	A textual description of this installed piece of software, including the manufacturer, revision, the name by which it is commonly known, and optionally, its serial number.

hrSWRunEntry	1.3.6.1.2.1.25.4.2.1		not-accessible	A (conceptual) entry for one piece of software running on the host Note that because the installed software table only contains information for software stored locally on this host, not every piece of running software will be found in the installed software table. This is true of software that was loaded and run from a non-local source, such as a network-mounted file system. As an example of how objects in this table are named, an instance of the hrSWRunName object might be named hrSWRunName.1287
hrSWRunGroup	1.3.6.1.2.1.25.7.3.4			The Host Resources Running Software Group.
PRO hrSWRunID	1.3.6.1.2.1.25.4.2.1.3	ProductID	read-only	The product ID of this running piece of software.
I32 hrSWRunIndex	1.3.6.1.2.1.25.4.2.1.1	Integer32	read-only	A unique value for each piece of software running on the host. Wherever possible, this should be the system's native, unique identification number.
NUM hrSWRunName	1.3.6.1.2.1.25.4.2.1.2	InternationalDisplayString	read-only	A textual description of this running piece of software, including the manufacturer, revision, and the name by which it is commonly known. If this software was installed locally, this should be the same string as used in the corresponding hrSWInstalledName.

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.
NUM hrSystemInitialLoadParameters	1.3.6.1.2.1.25.1.4	InternationalDisplayString	read-write	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.
I32 hrSystemMaxProcesses	1.3.6.1.2.1.25.1.7	Integer32	read-only	The maximum number of process contexts this system can support. If there is no fixed maximum, the value should be zero.

hrStorageTable	1.3.6.1.2.1.25.2.3		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.

I32 hrStorageSize	1.3.6.1.2.1.25.2.3.1.5	Integer32	read-write	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.

A value unknown(1) indicates that the current state of the device is unknown. running(2) indicates that the device is up and running and that no unusual error conditions are known. The warning(3) state indicates that agent has been informed of an unusual error condition by the operational software (e.g., a disk device driver) but that the device is still 'operational'. An example would be a high number of soft errors on a disk. A value of testing(4), indicates that the device is not available for use because it is in the testing state. The state of down(5) is used only when the agent has been informed that the device is not available for any use.
C32 hrDeviceErrors	1.3.6.1.2.1.25.3.2.1.6	Counter32	read-only	The number of errors detected on this device. 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.

TIK hrSWInstalledLastChange	1.3.6.1.2.1.25.6.1	TimeTicks	read-only	The value of sysUpTime when an entry in the hrSWInstalledTable was last added, renamed, or deleted. Because this table is likely to contain many entries, polling of this object allows a management station to determine when re-downloading of the table might be useful.
TIK hrSWInstalledLastUpdateTime	1.3.6.1.2.1.25.6.2	TimeTicks	read-only	The value of sysUpTime when the hrSWInstalledTable was last completely updated. Because caching of this data will be a popular implementation strategy, retrieval of this object allows a management station to obtain a guarantee that no data in this table is older than the indicated time.
TIK hrSystemUptime	1.3.6.1.2.1.25.1.1	TimeTicks	read-only	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.

hostResourcesMibModule	1.3.6.1.2.1.25.7.1			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.

hrStorageTable	1.3.6.1.2.1.25.2.3		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.
