Hi, I have a need to route different message types to different elasticsearch clusters. I realise I could do this by having different "elasticsearch" output blocks separated by "if" conditionals. However, that is wasteful and long winded... What I'd like to do is set a variable containing the list of hosts for the cluster corresponding to that message type. Is this possible? If so, how would you recommend I do this? Regards, David ---

The correct way to do this is using conditionals. A single Elasticsearch output can only send data to a single cluster. ---

You could try to use: [https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-hosts](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-hosts) With a value from your message. `hosts => ["my-cluster-%{cluster}:9200"]` PS: I didn't try it ---

In addition to what other folks have suggested, you can use the translate filter to look up a message type in a table and obtain a hostname. That way you don't have to reload the Logstash configuration when you want to update the mapping table. ---

Is the translate yaml dictionary file read once or each time the filter is applied? ---

The YAML file is periodically read. See [the documentation](https://www.elastic.co/guide/en/logstash/current/plugins-filters-translate.html#plugins-filters-translate-refresh_interval). ---
