Logstash has a rich collection of input, filter, codec, and output plugins.Check out theElastic Support Matrix to see which plugins are supported at various levels.

The plugins make up your Logstash pipeline.

• Integration plugins combine related plugins—inputs, outputs, and sometimes filters and codecs—into one package.

• Input plugins enable a specific source of events to be read by Logstash.

• Filter plugins perform intermediary processing on an event. Filters are often applied conditionally depending on the characteristics of the event.

• Codec plugins change the data representation of an event.Codecs are essentially stream filters that can operate as part of an input or output.

• Output plugins send event data to a particular destination.Outputs are the final stage in the Logstash event pipeline.
