How catrapd Formats Traps

If automatic formatting of SNMP traps is enabled, catrapd uses the TRAP and MIB tables in the CAITRPDB database to determine which traps to format. A TRAP record identified by a unique Eid (Enterprise ID), Generic, and Specific key contains information needed to format one trap. A MIB record identified by a unique Name key contains information about one MIB. All TRAP and MIB records have Enable columns that control which traps to translate. A MIB is a collection of related traps generated by one software program or hardware device. One company or organization usually compiles a MIB.

• If an incoming trap matches the Eid (Enterprise ID), Generic, and Specific trap fields, and the corresponding TRAP and MIB records are enabled, CATRAPD translates it to readable form.
• catrapd uses the Format, Args, and AlarmName columns of the matching TRAP record and the Variable Bindings (VarBinds) from the incoming trap to create the final text in the following format:

  %CATD_I_066, AlarmName: unique variable-text ...
  

  Where AlarmName is from the TRAP record and unique variable-text is created by substituting selected VarBinds into the Format column of the corresponding record.

• catrapd sends the formatted traps to the Event Management daemon for further processing.
