amdocs Bath team (in charge of search-data-service, @Colin Burns) is planning to upgrade elasticsearch to 6.1.2 (based on AT&T approved versions) by the end of June.
- Current ELK versions: elasticsearch 2.4, kibana 4.6 (no logstash is being used)
- To create the dashboards with enhanced Kibana features, upgrading to version 5.5 or above for all ELK stack is desired. (note: ONAP Logging project is using 5.5)
- Upgrade from 2.x to 5.x or above requires "Full Cluster-restart Upgrade".
- search-data-service should reflect this upgrade
- deploy/configure the right versions
- potentially update relevant API methods for the elasticsearch data management.
