How to use Filebeat?
Filebeat is great for solving a specific problem: you log to files, and you want to either: 1 ship directly to Elasticsearch. This works if you want to just “grep” them or if you log in JSON (Filebeat can parse JSON). Or, if you want to use Elasticsearch’s Ingest for parsing and enriching (assuming the performance and functionality of Ingest fits your needs) 2 put them in Kafka/Redis, so another shipper (e.g. Logstash, or a custom Kafka consumer) can do the enriching and shipping. This assumes that the chosen shipper fits your functionality and performance needs 3 ship to Logstash. Like the above, except you’re relying on Logstash to buffer instead of Kafka/Redis. Simpler, but less flexible and fault tolerant
