Nuget Packages - MIB Extractor

This package provides a comprehensive SNMP MIB (Management Information Base) parser library specifically designed for .NET applications that need to extract, analyze, and navigate Object Identifier (OID) definitions from standard MIB files used in network management and monitoring systems.

​One of the most challenging aspects of building SNMP-based network monitoring tools is working with MIB files—complex text documents that define the structure and semantics of management information for network devices. MIB files contain hundreds or thousands of OID definitions organized in hierarchical trees, with intricate parent-child relationships, metadata about data types, access levels, and detailed descriptions. Manually parsing these files or building custom parsers for each project is time-consuming, error-prone, and requires deep knowledge of the MIB syntax specifications (SMIv1, SMIv2).

​Instead of implementing complex regex patterns, handling multi-pass parsing logic, and manually resolving OID hierarchies, this library handles the entire process automatically. Simply provide the path to any standard MIB file, and the parser automatically extracts all OBJECT IDENTIFIER assignments, OBJECT-TYPE definitions, NOTIFICATION-TYPE definitions (traps and informs), MODULE-IDENTITY metadata, and TEXTUAL-CONVENTION custom type definitions. The library intelligently resolves parent-child relationships, builds the complete OID tree structure with full path resolution (e.g., "1.3.6.1.2.1.1.1.0"), and provides rich metadata access including syntax types, access levels (read-only, read-write, etc.), status indicators (current, deprecated, obsolete), descriptions, units, index definitions, and reference information.

​This automation ensures your SNMP applications can dynamically work with any MIB file without manual intervention, eliminating the need to hardcode OID mappings or maintain separate lookup tables. The parser handles complex scenarios like unresolved dependencies, circular references, and missing parent nodes, providing clear warning messages for troubleshooting. Whether building network monitoring dashboards, SNMP query tools, device discovery applications, or MIB documentation generators, developers can leverage this library to quickly integrate MIB parsing capabilities.

​The integration is straightforward—instantiate the MIBParser with a file path, and immediately access parsed data through intuitive methods. Retrieve all nodes as a dictionary for fast lookups, get flat lists of resolved OIDs sorted hierarchically, look up specific nodes by OID string, export tree structures to text for visualization, or filter by node types (scalars, tables, notifications) for targeted processing. The library also provides automatic detection of SNMP structure patterns, identifying scalar objects, SNMP tables, table entries, and table columns based on standard conventions.

​Key Features:

​
• Pre-initialized standard SNMP roots (iso, internet, mgmt, private, enterprises)
• Parse standard SNMP MIB files (SMIv1/SMIv2 format)
• Extract OBJECT-TYPE, NOTIFICATION-TYPE, and TEXTUAL-CONVENTION definitions
• Automatic OID hierarchy resolution with parent-child navigation
• Rich metadata extraction (syntax, access, status, descriptions, units)
• Export flat OID lists or hierarchical tree views
• Support for table structures, index definitions, and augmentation
• Comprehensive warning system for parsing issues

​ Note: This library is designed for .NET Core and .NET Framework applications requiring SNMP MIB parsing capabilities.
