Elasticsearch audit logs can be effectively indexed and analyzed using Filebeat, especially after the deprecation of the index output type in version 6.7.0 and its complete removal in version 7.0.0. Filebeat, a separate process from Elasticsearch, takes on the task of indexing audit logs, relieving the Elasticsearch nodes from this load and allowing them to focus solely on storing events. By configuring Filebeat alongside Elasticsearch, administrators can manage audit logs more efficiently and take advantage of features such as event filtering and sending logs to external systems like Logstash or Kafka for further processing. This setup not only prevents data loss during high load scenarios but also enhances analysis capabilities in Kibana by allowing the correlation of various types of logs. Additionally, Filebeat's configuration flexibility and ability to handle multiple Elasticsearch clusters provide robust options for managing logs across distributed environments.
