> lines:
> {noformat}
> 2019-12-18 16:38:00.171 INFO (main) [ ] o.a.s.c.SolrZkServerProps Reading
> configuration from: /var/solr/data/zoo.cfg

> EMBEDDED STANDALONE ZOOKEEPER SERVER at port 9983
> 2019-12-18 16:38:00.673 INFO (main) [ ] o.a.s.c.ZkContainer Zookeeper
> client=localhost:9983 {noformat}
> In addition we should log a WARN line about not using it in production
> {noformat}
> WARN (main) [ ] o.a.s.c.SolrZkServer Embedded Zookeeper is not supported in
> production environments{noformat}
> This is already stated on the "[Taking Solr to
> production|https://lucene.apache.org/solr/guide/8_3/taking-solr-to-production.html#going-to-production-with-solrcloud]";
> RefGuide page. We should also add a more prominent WARNING box to RefGuide
> about the same.
