  1. You can simulate this by shutting down either of the clusters. Let’s shut down cluster A in this tutorial.

  2. Start Logstash with the same configuration file. (This step is not required in real use cases where Logstash ingests continuously.)

    Shell 
    ### On Logstash server ###
bin/logstash -f multiple_hosts.conf

  3. Observe all Logstash traffic will be redirected to cluster B automatically.

    Tip

    You should also redirect all search traffic to the clusterB cluster during this time.

  4. The two data streams on cluster B now contain a different number of documents.

    • data streams on cluster A (down)

      • 50 documents in logs-generic-default-replicated_from_clusterb
      • 50 documents in logs-generic-default

    • data streams On cluster B (up)

      • 50 documents in logs-generic-default-replicated_from_clustera
      • 150 documents in logs-generic-default
