elasticsearch – kibana timelion reads the wrong index (two index names are similar)

It appears you are trying to use Timelion to visualize data from an Elasticsearch index pattern. The index parameter in the es() function specifies the index pattern to retrieve data from.

Based on the information provided, it seems that the index pattern “b-” is being matched and returned, while the index pattern “a-b-” is not. This could be due to a variety of reasons, including incorrect syntax in the index pattern, a lack of indices matching the pattern in the Elasticsearch cluster, or a configuration issue with Timelion or Elasticsearch.

To retrieve data from the “a-b-*” index pattern, try using the following syntax in Timelion:

scss
Copy code
es(index=a-b-*).label(“Events”)
Make sure to check the Elasticsearch cluster and Timelion configuration to ensure that the desired indices are available and accessible.
