Kibana 7.12.0edit

For information about the Kibana 7.12.0 release, review the following information.

Breaking changesedit

Breaking changes can prevent your application from optimal operation and performance. Before you upgrade to 7.12.0, review the breaking changes, then mitigate the impact to your application.

Removes geo threshold alert type

Details
Geo containment alerts and the Geo threshold alert type have similar functionality, so the Geo threshold alert type has been removed. For more information, refer to #89632.

Impact
Use Geo containment alerts.

New saved object upgrade migrations algorithm

Details
When you upgrade to 7.12.0, Kibana uses a new algorithm to migrate saved objects to reduce the downtime caused by temporary issues, such as network errors or temporarily overloaded Elasticsearch clusters. With the new algorithm, Kibana now retries the failed migrations without user intervention, which allows the migration to continue after the issues are resolved. For more information, refer to saved object upgrade migrations.

Impact
Before you upgrade to 7.12.0, review the documentation for rolling back to a previous version of Kibana.

Kibana support for CCS

Details
In 7.12.0, Kibana introduces a major incompatibility with cross-cluster search. When one or more remote Elasticsearch clusters use a version prior to 7.12.0, Discover, Maps, Canvas, and Logs are unable to display the cluster data. For information about the cross-cluster search limitations in Kibana, refer to #94965.

Impact
To display the cluster data in Discover, load documents directly from _source.

  1. Open the main menu, then click Stack Management > Advanced Settings.
  2. Go to discover:searchFieldsFromSource, then select On.

Known issuesedit

Saved object migrations

When upgrading to 7.12.0, Kibana retries failed saved object migrations without user intervention.

Impacts include:

  • In 7.12.0, upgrade migrations fail because of a large number of documents in the .kibana index when you use Fleet.
  • Corrupt saved objects caused by manual editing or integrations.
  • User-defined index templates that cause new .kibana* indices to have incompatible settings or mappings.
  • An unhealthy Elasticsearch cluster.
  • Different versions of Kibana connected to the same Elasticsearch index.
  • Incompatible xpack.tasks.index configuration setting.

If your upgrade migration fails repeatedly, refer to preventing migration failures.

Cluster performance degradation

Details:

Kibana fails to update and delete search sessions objects created in non-default spaces.

Impact: Cluster performance degrades due to a flooding of async search API usage. For information on the workaround for 7.12.0, refer to #96124.

For information on the fix in 7.12.1, refer to #96123.

Deprecationsedit

The following functionality is deprecated in 7.12.0, and will be removed in 8.0.0. Deprecated functionality does not have an immediate impact on your application, but we strongly recommend you make the necessary updates after you upgrade to 7.12.0.

Deprecates services.callCluster in alerts and actions executors

Details
Deprecates services.callCluster in the alert and action type executors. For more information, refer to #86474.

Impact
Use services.scopedClusterClient.

Deprecates configuring [kib] with a server.host value of 0

Details
In the new version of joi, 0 is an invalid hostname. When upgraded, the extra validate function can be removed. For more information, refer to #87114.

Impact
To bind to all interfaces, use 0.0.0.0.

Deprecates the use of elasticsearch.logQueries

Details
When logging.verbose: true or logging.root.level: 'debug', Elasticsearch query logs are now always shown. In 7.11.0 and earlier, Elasticsearch query logs were not included in verbose logging unless elasticsearch.logQueries was configured. For more information, refer to #89296.

Impact
To use verbose logging without Elasticsearch query logs, configure the query logs to off in kibana.yml:

logging:
  loggers:
    - name: elasticsearch.query
      level: off

To log the elasticsearch query only:

logging:
  loggers:
    - name: elasticsearch.query
      level: all
      appenders: [console]
