**To get information about an Amazon Kendra data source connector**

The following ``describe-data-source`` gets information about an Amazon Kendra data source connector. You can view the configuration of a data source connector, and read any error messages if the status shows a data source connector "FAILED" to completely create. ::

    aws kendra describe-data-source \
        --id exampledatasource1 \
        --index-id exampleindex1
