Kibana Server Not Ready

Question

I configured Elastic search, Kibana and log stash cluster. Elastic search is working fine, but Kibana is displaying an error stating Kibana Server Not Ready.

Logs shows

First, try deleting the versioned indices and then restart as suggested above:

curl -XDELETE http://localhost:9200/.kibana_1

systemctl restart Kibana

If it doesn't work then verify you have a versioned index that's been created, e.g. byte counts the same, etc. After that then delete the original .kibana:

curl -XDELETE http://localhost:9200/.kibana

then alias it:

curl -X POST "localhost:9200/_aliases" -H 'Content-Type: application/json' -d' { "actions" : [ { "add" : { "index" : ".kibana_1", "alias" : ".kibana" } } ] }'

Then restart kibana.

I just followed the suggestion that came with the error:

If no other Kibana instance is attempting migrations, you can get past this message by deleting index .kibana_task_manager_1 and restarting Kibana.

curl -XDELETE http://localhost:9200/.kibana_task_manager_1

I then restarted Kibana

This is caused by the version mismatch between the Elastic Search and Kibana, Use the below versions while Setting up Elastic search and Kibana version matrix documented by the Elastic.co

If you dont care about loosing dashboard/vizu:

curl -XDELETE http://localhost:9200/.kibana*

This is the only solution, exactly like elasticsearch, you cant never recover data without a snapshot.

If there is a already .kibana_1 index, check that .kibana alias exists too, or create it:

curl -XPUT https://XXXXX/.kibana_1/_alias/.kibana

(same thing for task manager index).
