Netcool mib2rules 5.3

Netcool mib2rules is a command-line utility used to convert SNMP MIB definitions into event-processing rules for the Netcool/OMNIbus SNMP Trap Probe (nco_p_mttrapd). It automates the otherwise manual task of mapping trap Object Identifiers (OIDs) and varbinds to Netcool event fields, helping standardize and normalize traps from diverse network and IT devices.

What it does

• Parses SMIv1 and SMIv2 MIBs and discovers traps and their parameters.
• Generates probe rules that map traps to fields such as summary/text, severity, class, and alert group.
• Produces helpful lookup structures and comments to aid further customization.
• Reduces onboarding time for new vendors/devices and minimizes human error in rule creation.

Typical use

• Import vendor MIBs to quickly create a baseline ruleset for the SNMP Trap Probe.
• Review and refine the generated mappings (e.g., adjust severities, summaries, and classifications).
• Deploy the rules to the probe and iterate as needed based on live events.

Benefits

• Faster MIB-to-event onboarding with consistent mapping.
• Easier maintenance compared to writing rules from scratch.
• Clear starting point for tailoring trap handling to operational standards.

In short, mib2rules streamlines turning MIB knowledge into actionable Netcool/OMNIbus probe logic, making SNMP trap ingestion more reliable and easier to maintain.
