Category: Domain: Server/Host Monitoring
Description: Vendor extension to HOST-RESOURCES-MIB (RFC 2790) providing additional host resource monitoring objects for system management.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is HOST-RESOURCES-V2-MIB?
HOST-RESOURCES-V2-MIB is a vendor extension supplementing the IETF standard HOST-RESOURCES-MIB (RFC 2790), adding further objects for host computer management beyond what the base standard defines. As an extension of the Host Resources framework, it is intended to cover general host-level management data applicable across operating systems and hardware architectures, independent of any specific vendor's network stack. Its purpose is squarely hardware/software status monitoring: the base HOST-RESOURCES-MIB family covers system uptime, storage/disk usage, running processes, installed software, and device status, and this V2 extension supplements those categories with additional host attributes. It has an explicit, direct dependency on RFC 2790 HOST-RESOURCES-MIB, whose System and Interface groups it builds upon. Consulting the HOST-RESOURCES-V2-MIB RFC alongside RFC 2790 is useful when deploying it on general-purpose servers, workstations, or any managed host running an SNMP agent that exposes OS-level resource data to a network management system.
IPNetwork Monitor allows you to monitor SNMP objects defined in HOST-RESOURCES-V2-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.
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer
- general-purpose host computers/servers running an SNMP agent
Monitoring Examples
No concrete object names were available in the source sample for this module, so specific polling scenarios cannot be described from the provided data; conceptually, an admin using the parent HOST-RESOURCES-MIB framework would poll analogues of hrSystemUptime, hrStorageTable, and hrSWRunTable, and this V2 extension would supply additional host attributes alongside them. Without sample objects, no invented object names are given here to avoid misrepresenting the module's actual contents.

How to Use in IPNetwork Monitor
Example using hrStorageUsed OID:
Select a host computer or server running an SNMP agent as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type hrStorageUsed into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the amount of this storage entry currently allocated, in the storage's own allocation units. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if usage approaches the storage's total capacity (e.g. above 85-90%), since running low on storage can cause application or logging failures. Click Finish to create the monitor; you can adjust any parameter later.

| BIT hrPrinterDetectedErrorState | 1.3.6.1.2.1.25.3.5.1.2 | Bits | 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 # hrDeviceStatus lowPaper 0 warning(3) or down(5) noPaper 1 warning(3) or down(5) lowToner 2 warning(3) or down(5) noToner 3 warning(3) or down(5) doorOpen 4 warning(3) or down(5) jammed 5 warning(3) or down(5) offline 6 warning(3) or down(5) serviceRequested 7 warning(3) or down(5) inputTrayMissing 8 warning(3) or down(5) outputTrayMissing 9 warning(3) or down(5) markerSupplyMissing 10 warning(3) or down(5) outputNearFull 11 warning(3) or down(5) outputFull 12 warning(3) or down(5) inputTrayEmpty 13 warning(3) or down(5) overduePreventMaint 14 warning(3) or down(5) If multiple conditions are currently detected and 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. This object is useful for alerting an operator to specific warning or error conditions that may occur, especially those requiring human intervention. Because error bits 8 through 14 can indicate a printer that is still functioning, the corresponding (recommended) printer hrDeviceStatus can be either warning(3) or down(5). New bits may be defined by standards-track MIB modules but the maximum size of instances of this variable should be 128 octets. |

| 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. | |

| 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 | 1.3.6.1.2.1.25.7.2.4 | The optional 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. |

| NUM hrSWRunPath | 1.3.6.1.2.1.25.4.2.1.4 | InternationalDisplayString | read-only | A description of the location on long-term storage (e.g. a disk drive) from which this software was loaded. |
| hrSWRunPerf | 1.3.6.1.2.1.25.5 | |||
| I32 hrSWRunPerfCPU | 1.3.6.1.2.1.25.5.1.1.1 | Integer32 | read-only | The number of centi-seconds of the total system's CPU resources consumed by this process. Note that on a multi-processor system, this value may increment by more than one centi-second in one centi-second of real (wall clock) time. |
| hrSWRunPerfEntry | 1.3.6.1.2.1.25.5.1.1 | not-accessible | A (conceptual) entry containing software performance metrics. As an example, an instance of the hrSWRunPerfCPU object might be named hrSWRunPerfCPU.1287 | |

| TIK hrSystemUptimeEx | 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 MIB-II [3] because sysUpTime is the uptime of the network management portion of the system. |
RFC description
Defines a uniform set of managed objects for host computer management — covering system information, storage resources, devices, running software, installed software, and file systems — as specified in the IETF Internet Draft draft-krupczak-hostmibv2-01 (1998/1999), a proposed Version 2 revision that was never published as an RFC; the official update to RFC 1514 was instead published as RFC 2790 (HOST-RESOURCES-MIB).
