Elastic Agent to Logstash to Elasticsearch clusters and/or additional destinations
Use when
Data collected by Elastic Agent needs to be routed to different Elasticsearch clusters or non-Elasticsearch destinations depending on the content
Example

Let’s take an example of a Windows workstation, for which we are collecting different types of logs using the System and Windows integrations. These logs need to be sent to different Elasticsearch clusters and to S3 for backup and a mechanism to send it to other destinations such as different SIEM solutions. In addition, the Elasticsearch destination is derived based on the type of datastream and an organization identifier.

In such use cases, agents send the data to Logstash as a routing mechanism to different destinations. Note that the System and Windows integrations must be installed on all Elasticsearch clusters to which the data is routed.

Sample config
input {
  elastic_agent {
    port => 5044
  }
}
filter {
  translate {
    source => "[http][host]"
    target => "[@metadata][tenant]"
    dictionary_path => "/etc/conf.d/logstash/tenants.yml"
  }
}
output {
  if [@metadata][tenant] == "tenant01" {
    elasticsearch {
      cloud_id => "<cloud id>"
      api_key => "<api key>"
    }
  } else if [@metadata][tenant] == "tenant02" {
    elasticsearch {
      cloud_id => "<cloud id>"
      api_key => "<api key>"
    }
  }
}
