What is Logstash?
Logstash is a tool that is used to collect, filter/parse, and emit the data for future use. Collect, parse, and emit are divided into three sections, which are called input, filter, and output:
- The input section is used to read the data from external sources. The common input sources are File, TCP port, Kafka, and so on.
- The filter section is used to parse the data.
- The output section is used to emit the data to some external source. The common external sources are Kafka, Elasticsearch, TCP, and so on.
