The test environment deployed for ELK consisted of three Elasticsearch servers to provide quorum, a Logstash server, and a Kibana server. The ECS environment consisted of two federated ECS appliances.
Data was ingested into the ELK environment from ECS by the ECS syslog forwarder. ECS data access logs (which capture transactional data from client to ECS) were used for validating the frozen tier and for the searchable snapshot functions of Elastic. It also provides customers an overview of how you can ingest the ECS access log data and easily search and visualize the transactional activities of ECS.
