What is Kibana Kibana 'Discover' tab not showing data

Understanding Kibana

Kibana is a powerful visualization tool that is part of the Elastic Stack, used primarily for exploring, visualizing, and analyzing data stored in Elasticsearch. It provides a user-friendly interface to create dashboards, perform searches, and gain insights from your data.

Symptom: 'Discover' Tab Not Showing Data

One common issue users encounter is the 'Discover' tab in Kibana not displaying any data. This can be frustrating, especially when you know data exists in your Elasticsearch indices.

Details About the Issue

The 'Discover' tab is designed to allow users to explore their data by querying Elasticsearch indices. When no data is displayed, it often points to a configuration issue rather than a problem with the data itself. The most frequent causes are incorrect index patterns or misconfigured time filters.

Index Pattern Issues

An index pattern in Kibana defines which indices to query in Elasticsearch. If the pattern does not match any existing indices, no data will be displayed. For more information on setting up index patterns, visit the Kibana Index Patterns Documentation.

Time Filter Settings

The time filter in Kibana allows users to specify the time range for the data they want to view. If the time filter is set outside the range of your data, the 'Discover' tab will not show any results. Learn more about time filters in the Kibana Time Filter Guide.

Steps to Fix the Issue

Step 1: Verify the Index Pattern

Go to the 'Management' section in Kibana and select 'Index Patterns'. Ensure that the index pattern matches the indices in your Elasticsearch cluster. If necessary, create a new index pattern that correctly matches your data.

Step 2: Adjust the Time Filter

In the 'Discover' tab, check the time filter settings in the top-right corner. Adjust the time range to ensure it encompasses the data you expect to see. You can select a predefined range or set a custom time frame.

Step 3: Refresh the Index Pattern

If changes have been made to the indices, such as adding new fields, refresh the index pattern. Go to 'Management' > 'Index Patterns', select the relevant pattern, and click 'Refresh'.

Step 4: Check for Data in Elasticsearch

Use the Elasticsearch Dev Tools in Kibana to run a query and verify that data exists in the indices. For example, use the following query to check for data:

GET /your-index-name/_search{ "query": { "match_all": {} }}

If the query returns results, the issue is likely with the Kibana configuration.

Conclusion

By verifying the index pattern and adjusting the time filter, you can resolve the issue of the 'Discover' tab not showing data in Kibana. For further assistance, consider visiting the Kibana Discuss Forum for community support.
