Kibana is a powerful data visualization and exploration tool used primarily with Elasticsearch. It allows users to create visualizations and dashboards, enabling them to analyze large volumes of data efficiently. Kibana is widely used for log and time-series analytics, application monitoring, and operational intelligence use cases.
When working with Kibana, you might encounter an error stating that a 'Saved field parameter is now invalid.' This error typically appears when attempting to load a saved visualization or dashboard. The symptom is often a broken visualization or a dashboard that fails to display data correctly.
This issue arises when a field used in a saved object, such as a visualization or dashboard, has been removed or altered in the Elasticsearch index pattern. Changes in the underlying data schema, such as renaming or deleting fields, can lead to this error. As a result, Kibana cannot find the expected field, causing the visualization to break.
To resolve this issue, you need to update the saved object to use valid fields or recreate the visualization with the correct fields. Follow these steps:
First, identify which visualizations or dashboards are affected by this issue. Attempt to load each saved object and note any that display the error.
Navigate to the Index Patterns section in Kibana. Ensure that the index pattern associated with the affected visualization is up-to-date and includes all necessary fields.
To edit a visualization, go to the Visualize section, select the affected visualization, and make the necessary changes.
After making the changes, save the updated visualization. Test it to ensure that it displays data correctly without any errors.
By following these steps, you can resolve the 'Saved field parameter is now invalid' error in Kibana. Regularly reviewing and updating your index patterns and visualizations can help prevent such issues in the future. For more detailed guidance, refer to the Kibana Documentation.
