4.0.0

  • Initial Release of SNMP Integration Plugin, incorporating logstash-input-snmp and logstash-input-snmptrap. Independent changelogs for previous versions can be found:
  • Migrated the SNMP4J clients to Java and unified the MIB file reader and field mapper to be used by all plugins.
  • Changed the read approach for smilib .dic MIBs files.
  • Changed to use the MultiThreadedMessageDispatcher by default.
  • Instead of using one client instance per host, it now uses a single multi-version client for all hosts.
  • Migrated logstash-input-snmptrap client from ruby-snmp to SNMP4J
    • The event message content was changed from the ruby SNMP::SNMPv1_Trap object inspect representation to a hash dump based on the RFC definition. It also adds the fields as [@metadata][input][snmptrap][pdu][<name>] metadata.
    • Added supported_transports and supported_versions options.
  • Standardized the logstash-input-snmp and logstash-input-snmptrap settings, supported MIB formats and features.
    • Both plugins now support .dic (libsmi) and .yaml (ruby-snmp) MIB formats.
    • Added the oid_mapping_format option to configure how the OID field is mapped in the Logstash event.
    • Added the oid_map_field_values option to enable/disable OID field values mapping.
    • The logstash-input-snmptrap now supports the logstash-input-snmp features: mib_paths, use_provided_mibs, oid_root_skip, oid_path_length.
  • The logstash-input-snmptrap yamlmibdir was deprecated in favor of mib_paths.
  • Updated the logstash-input-snmptrap docs to include the same logstash-input-snmp instructions on how importing MIB files.
  • Added SNMPv3 support to logstash-input-snmptrap.
  • Added multi-thread support to logstash-input-snmp and logstash-input-snmptrap plugins.
    • Upgraded SNMP4J version to 3.8.0, it has a better multi-threading support and has fixed several issues.
