Hi,

I don't think this is possible as the elasticsearch input takes the query as an ElasticSearch DSL document.

However, there are a few possibilities that you could try:

  1. If you have a platinum or enterprise license you are allowed to use the ElasticSearch JDBC agent. in this case, you could use the jdbc-input plugin to do the query.
  2. The second option is the Elasticsearch SQL API. You could utilize this API using the http_poller plugin.

Best regards
Wolfram
