Changelog

Sourced from sensu-plugin's changelog.

[3.0.1] - 2018-01-07

Fixed

• locked mixlib-cli dep to ~> 1.5 as 2.0 removes ruby support for < 2.5 (@​majormoses)

[3.0.0] - 2018-12-04

Breaking Changes

• renamed event mapping utility function map_v2_event_into_v1 to match naming change to Sensu Go map_go_event_into_ruby (@​jspaleta)
• renamed mutator and handler mixin arguments from --map-v2-event-into-v1 to match naming change to Sensu Go --map-go-event-into-ruby (@​jspaleta)
• renamed envar option from SENSU_MAP_V2_EVENT_INTO_V1 to SENSU_MAP_GO_EVENT_INTO_RUBY (@​jspaleta)
• updated map_go_event_into_ruby logic to account for entity attribute refactor (@​jspaleta)

Added

• map_go_event_info_ruby now takes optional map_annotation argument to indicate annotation key
  holding json string to be mapped into ruby entity attributes
  default value is "sensu.io.json_attributes"
  optional envvar SENSU_MAP_ANNOTATION to use as environment override (@​jspaleta)
• add mutator-go-into-ruby.rb binary. This mutator command can be used to mutate Sensu Go events into Sensu Core 1.x events (@​jspaleta)

[2.7.0] - 2018-09-12

Added

• Added map_v2_event_into_v1 method to Utils for all plugin classes to use. (@​jspaleta)
• Added --map-v2-event-into-v1 runtime commandline option to base Handler and Mutator classes. (@​jspaleta)
• Alternatively set envvar SENSU_MAP_V2_EVENT_INTO_V1=1 and handlers/mutators will automatically attempt to map 2.x event data. (@​jspaleta)
• New cli option/envvar makes it possible to use sensu-plugin based handlers/mutators
  with Sensu 2.0 events until they provide native 2.0 event support internally. (@​jspaleta)
• Mapping function sets and checks for boolean event attribute 'v2_event_mapped_into_v1',
  to prevent mapping from running multiple times in same pipeline. (@​jspaleta)

[2.6.0] - 2018-08-28

Fixed

• Fix paginated_get for backward compatibility with Sensu API < 1.4 (@​cwjohnston).

[2.6.0] - 2018-08-28

Added

[2.5.0] - 2018-04-03
