Kibana 8.17.5

The 8.17.5 release includes the following enhancements and fixes.

Known issues

edit

Observability AI assistant Knowledge Base entries with empty text can lead to Kibana OOM or restarts.

Details
The semantic text migration can cause excessive traffic to a cluster and might eventually cause the Kibana instance to crash due to OOM, together with increase of requests to Elasticsearch & ML nodes.

The problem can occur when there is one or more empty text Knowledge Base documents.

The migration script does not handle this scenario and will indefinitely update the same document.

Because the document update involves semantic_text an ML node is kept warm further increasing the costs.

The issue involves semantic_text field type (and thus the semantic_text migration which is causing this issue), introduced in the knowledge base feature in 8.17.

Workaround

Pause the Kibana instance if possible. If not possible, skip this step.

Run a dry run query to identify if you have empty Knowledge Base documents. If you have at least 1 hit, you can be affected by the problem.

GET .kibana-observability-ai-assistant-kb/_search
{
  "query": {
    "bool": {
      "must": [{ "exists": { "field": "text" }}],
      "must_not": [ { "wildcard": { "text": "*" } }
      ]
    }
  }
}

Execute the deletion. For extra safety, you might want to trigger a snapshot before executing it.

POST .kibana-observability-ai-assistant-kb/_delete_by_query
{
  "query": {
    "bool": {
      "must": [{ "exists": { "field": "text" }}],
      "must_not": [ { "wildcard": { "text": "*" } }
      ]
    }
  }
}
