  log   [16:03:07.086] [info][plugins-service] Plugin "metricsEntities" is disabled.

  log   [16:03:07.209] [warning][config][deprecation] Starting in 8.0, the Kibana logging format will be changing. This may affect you if you are doing any special handling of your Kibana logs, such as ingesting logs into Elasticsearch for further analysis. If you are using the new logging configuration, you are already receiving logs in both old and new formats, and the old format will simply be going away. If you are not yet using the new logging configuration, the log format will change upon upgrade to 8.0. Beginning in 8.0, the format of JSON logs will be ECS-compatible JSON, and the default pattern log format will be configurable with our new logging system. Please refer to the documentation for more information about the new logging format.

  log   [16:03:07.210] [warning][config][deprecation] The default mechanism for Reporting privileges will work differently in future versions, which will affect the behavior of this cluster. Set "xpack.reporting.roles.enabled" to "false" to adopt the future behavior before upgrading.
