MIBGen 1.0 Rust SNMP Agent Builder FAQ

MIBGen is the Rust edition of iReasoning SNMP Agent Builder. It reads SMIv1 and SMIv2 MIB definitions and creates an immediately compilable Rust agent project with typed scalar and table models, provider interfaces, configuration, tests, and build support. Application developers connect the generated providers to their own data.

The Java edition is the established JMX-based toolkit and includes AgentX workflows. MIBGen is a native Rust workflow that produces standalone Cargo projects with typed models, protected provider code, atomic publication, and integrated build-and-run controls. The editions are separate products; choose the one that matches your application language and architecture.

Generated agents support SNMPv1, SNMPv2c, and SNMPv3. SNMPv3 includes authoritative engine handling, USM users, and VACM access control. Available security algorithms include HMAC-MD5, HMAC-SHA, SHA-2 authentication, and DES, 3DES, and AES privacy, subject to the selected agent configuration.

MIBGen is available for 64-bit Windows and Linux and for Apple silicon and Intel macOS. Development requires Rust 1.85 or newer, Cargo from the same toolchain, and the rustfmt component. The Rust edition does not require a JDK, JVM, JNI, or Java installation.

Rust edition access is currently sales-assisted. Contact iReasoning to discuss your agent project, supported platform, license, and delivery package. No unsigned Rust download or public Rust pricing is published on this page.

One license covers one identified commercial or internal SNMP agent product or project for the licensed named user. Maintenance releases, updates, supported platform builds, configurations, and deployed instances of that same agent remain part of the licensed agent. A separate product, customer-specific agent, independent project, replacement agent, or agent serving a different primary business purpose requires a new license.

There are no per-copy, per-device, per-instance, or other runtime royalties for authorized deployments of the licensed agent. You may deploy unlimited authorized copies or instances of that one agent. This does not authorize development of another agent and does not waive purchase, support, upgrade, tax, or separately negotiated fees.

MIBGen can generate a complete conceptual table, an OID group or subtree, or an SMIv2 OBJECT-GROUP limited to the objects in its OBJECTS clause. A project may use multiple targets from one or more independent SMIv1 or SMIv2 entry MIBs.

MIBGen does not offer individual scalars, notifications, compliance statements, inaccessible objects, ambiguous symbols, overlapping selections, or targets with unsupported index syntax. It also stops when required imports cannot be resolved. The Activity section reports the parser or selection diagnostic.

The generated Cargo project includes typed MIB schema, scalar and table models, OID and index encoding, provider skeletons, registration and validation, XML configuration, tests, build support, and integration hooks. It compiles and runs before application collectors are implemented; unfinished data is represented as absent rather than fabricated.

The runtime includes providers for MIB-II system and interfaces, address translation, IP, TCP, and UDP; IF-MIB ifXTable; IP-MIB ipAddressTable; Host Resources system, storage, device, partition, filesystem, software, and performance objects; and SNMPv3 USM and VACM management. MIBGen reuses these providers instead of generating a duplicate provider for the same OIDs.

Add Selected Targets introduces targets that are not already in the project. Synchronize Project regenerates schema-owned files for existing targets after a MIB revision. Check is read-only; Synchronize performs the update only after the revised schema and project pass validation.

No. Engineer-owned providers, application integration, project configuration, and provider tests are created once and preserved. Generator-owned schema files are tracked separately. If one of those generated files was edited manually, MIBGen stops instead of silently overwriting the change; restore the generated file and move custom logic into an engineer-owned file.

Yes. Add one or more independent entry MIBs. Imports are resolved beside each entry file, identical shared modules are deduplicated, and different files declaring the same module name are rejected as a version conflict.

Yes. The result is an independent Cargo project that can be built, tested, and run outside the MIBGen GUI using the compatible Rust agent developer kit. The agent uses its generated XML configuration and does not depend on Java, a JVM, or JNI.

Providers validate and publish complete typed snapshots instead of exposing a table while it is being modified. Publication either succeeds as one consistent update or leaves the previous snapshot active. GET, GET-NEXT, and GET-BULK therefore traverse one globally ordered OID view, and removing a row means publishing a new snapshot without that row.

Generated providers are operationally read-only by default, even when a MIB declares an object read-write or read-create. Safe writable support requires explicit transactional hooks to validate and prepare every assignment, commit atomically, undo partial commits, persist durable changes, and refresh row topology only after a successful transaction.

MIBGen creates config/SnmpAgent.xml. It controls the listener, protocol version, communities, USM users, VACM policy, MIB loading, and trap or INFORM destinations. Numeric IPv4 and IPv6 bind addresses are supported. The Rust runtime also retains many Java-style configuration names to make migration easier; unknown compatibility attributes are generally retained and ignored.

For generation, confirm that every imported module is beside its entry MIB and that selected targets are valid and non-overlapping. For Build or Run, wait for automatic toolchain validation, confirm the project manifest and generated files are valid, and build successfully before running. For SNMP timeouts, check the address, port, SNMP version, community or USM credentials, VACM permissions, process status, and host firewall. For an empty table, inspect Activity and confirm that its collector publishes rows with the expected indexes.
