Brief Explanation
This error occurs when Kibana dashboards fail to display data, resulting in empty or incomplete visualizations. Users may see blank panels or "No results found" messages instead of the expected data representations.
Common Causes
- Index pattern mismatch
- Incorrect time range selection
- Elasticsearch connectivity issues
- Insufficient permissions
- Data ingestion problems
- Incompatible Kibana and Elasticsearch versions
Troubleshooting and Resolution Steps
Verify index pattern:
- Go to Stack Management > Index Patterns
- Ensure the correct index pattern is selected for your dashboard
- Check if the index pattern matches your Elasticsearch indices
Check time range:
- Confirm that the selected time range in Kibana includes the period when data was ingested
- Try expanding the time range to see if data appears
Test Elasticsearch connectivity:
- Verify Elasticsearch is running and accessible
- Check Kibana server logs for connection errors
- Ensure correct Elasticsearch URL in kibana.yml configuration
Review permissions:
- Confirm the user has necessary permissions to view index data
- Check role-based access control (RBAC) settings if enabled
Investigate data ingestion:
- Verify data is being successfully ingested into Elasticsearch
- Use Elasticsearch API or Kibana Dev Tools to query the indices directly
Check version compatibility:
- Ensure Kibana and Elasticsearch versions are compatible
- Upgrade or downgrade components if necessary
Clear browser cache:
- Clear your browser's cache and cookies
- Try accessing the dashboard in an incognito/private browsing window
Rebuild index pattern:
- Delete and recreate the index pattern in Kibana
- Refresh field list to ensure all fields are recognized
Best Practices
- Regularly monitor Elasticsearch and Kibana logs for potential issues
- Implement alerting for data ingestion failures or dashboard errors
- Keep Elasticsearch and Kibana versions in sync and up to date
- Use Kibana's Monitoring feature to track cluster and index health
Frequently Asked Questions
Q: Why is my Kibana dashboard showing "No results found" for all visualizations?
A: This could be due to an incorrect time range selection, index pattern mismatch, or data ingestion issues. Verify your time range settings, check that your index pattern correctly matches your data, and ensure that data is being successfully ingested into Elasticsearch.
Q: How can I check if data is actually present in Elasticsearch?
A: You can use Kibana's Dev Tools console or the Elasticsearch API to query your indices directly. A simple GET request to your index (e.g., GET /your-index-name/_search) will return results if data is present.
Q: What should I do if Kibana can't connect to Elasticsearch?
A: First, ensure Elasticsearch is running and accessible. Check the Elasticsearch URL in your kibana.yml configuration file. Verify network connectivity and any firewall rules that might be blocking the connection. Review Kibana server logs for specific connection errors.
Q: Can version mismatches between Kibana and Elasticsearch cause data display issues?
A: Yes, version incompatibility can lead to various issues, including data not displaying correctly. Always ensure that your Kibana and Elasticsearch versions are compatible. Refer to the official Elastic documentation for version compatibility matrices.
Q: How do I refresh my Kibana index pattern if the data structure has changed?
A: Go to Stack Management > Index Patterns, select your index pattern, and click on the refresh fields button. This will update the field list based on the current index mapping. If issues persist, you may need to delete and recreate the index pattern.
