VMware MIB files contain information provided by ESXi hosts and vCenter Server to SNMP management software.
Management Information Base (MIB) files define the information that can be provided by managed devices. The MIB files define managed objects, described by object identifiers (OIDs) and variables arranged in a hierarchy. SMI structure of management information (RFC 2578) is the syntax used to write MIB files for specific product and function. These MIB files are versioned independently of product and can be used to identify event types and event data related information.
You can download these MIB files from https://kb.vmware.com/s/article/1013445.
Table 1. VMware MIB Files lists the MIB files provided by VMware and describes the information provided by each file.
| MIB File | Description |
|---|---|
| VMWARE-ROOT-MIB.mib | Contains VMware’s enterprise OID and top-level OID assignments. |
| VMWARE-ESX-AGENTCAP-MIB.mib | Defines the capabilities of the VMware agents by product versions. This file is optional and might not be supported by all management systems. |
| VMWARE-CIMOM-MIB.mib | Defines variables and trap types used to report on the state of the CIM Object Management subsystem. |
| VMWARE-ENV-MIB.mib | Defines variables and trap types used to report on the state of physical hardware components of the host computer. Enables conversion of CIM indications to SNMP traps. |
| VMWARE-OBSOLETE-MIB.mib | For use with versions of ESX/ESXi prior to 4.0. Defines OIDs that have been made obsolete to maintain backward compatibility with earlier versions of ESX/ESXi. Includes variables formerly defined in the files VMWARE-TRAPS-MIB.mib and VMWARE-VMKERNEL-MIB.mib. |
| VMWARE-PRODUCTS-MIB.mib | Defines OIDs to uniquely identify each SNMP agent on each VMware platform by name, version, and build platform. |
| VMWARE-RESOURCES-MIB.mib | Defines variables used to report information on resource usage of the VMkernel, including physical memory, CPU, and disk utilization. |
| VMWARE-SYSTEM-MIB.mib | The VMWARE-SYSTEM-MIB.mib file is obsolete. Use the SNMPv2-MIB to obtain information from sysDescr.0 and sysObjec ID.0. |
| VMWARE-TC-MIB.mib | Defines common textual conventions used by VMware MIB files. |
| VMWARE-VC-EVENT-MIB.mib | Defines traps sent by vCenter Server. Load this file if you use vCenter Server to send traps. |
| VMWARE-VMINFO-MIB.mib | Defines variables for reporting information about virtual machines, including virtual machine traps. |
Table 2. Other MIB Files lists MIB files included in the VMware MIB files package that are not created by VMware. These can be used with the VMware MIB files to provide additional information.
| MIB File | Description |
|---|---|
| ENTITY-MIB.mib | Allows the description of relationships between physical entities and logical entities managed by the same SNMP agent. See RFC 4133 for more information. |
| HOST-RESOURCES-MIB.mib | Defines objects that are useful for managing host computers. |
| HOST-RESOURCES-TYPES.mib | Defines storage, device, and filesystem types for use with HOST-RESOURCES-MIB.mib. |
| IEEE8021-BRIDGE-MIB | Defines objects for managing devices that support IEEE 802.1D. |
| IEEE8023-LAG-MIB | Defines objects for managing devices that support IEEE 802.3ad link aggregation. |
| IEEE8021-Q-BRIDGE-MIB | Defines objects for managing Virtual Bridged Local Area Networks. |
| IF-MIB.mib | Defines attributes related to physical NICs on the host system. |
| IP-MIB.mib | Defines objects for managing implementations of the Internet Protocol (IP) in an IP version-independent manner. |
| IP-FORWARD-MIB.mib | Defines objects for managing IP forwarding. |
| LLDP-V2-MIB.mib | Defines objects for managing devices using Linked Layer Discovery Protocol (LLDP). |
| SNMPv2-CONF.mib | Defines conformance groups for MIBs. |
| SNMPv2-MIB.mib | Defines the SNMP version 2 MIB objects. |
| SNMPv2-SMI.mib | Defines the Structure of Management Information for SNMP version 2. |
| SNMPv2-TC.mib | Defines textual conventions for SNMP version 2. |
| TCP-MIB.mib | Defines objects for managing devices using the TCP protocol. |
| UDP-MIB.mib | Defines objects for managing devices using the UDP protocol. |
