Kibana not showing data after images upgraded to 3.4

Solution Unverified - Updated

Environment

  • OpenShift Container Platform 3.3 upgraded to 3.4

Issue

After upgrading OpenShift Container Platform and all the images, data is sent from Fluentd to Elasticsearch but it is not shown in Kibana.
However data coming from new projects created after the upgrade are displayed without problems.

Resolution

Run the logging-deployer-template in mode upgrade so that Kibana index patterns are updated to the new metadata schema

$ oc new-app logging-deployer-template --param MODE=upgrade

Another way to manually achieve this is by accessing Kibana UI -> "Settings" -> "Indices", select one of the affected indices and click the "Refresh field list" button. Once completed, data for this index pattern should be displayed.

Root Cause

After upgrading OpenShift to the latest version the new aggregated logging images might be used. The new images may include some changes that require the existing data to be updated and that is why the upgrade should always be performed after updating to a newer minor version as stated in the documentation:
