Monitoring your index (Console)

Use the Amazon Kendra console to monitor the state of indexes and data sources. You can use this information to track the size and storage requirements of your index and to monitor the progress and success of synchronization between your index and data sources.

To view index metrics (Console)

  1. Sign into the AWS Management Console and open the Amazon Kendra console at https://console.aws.amazon.com/kendra/home.

  2. From the list of indexes, choose the index to view.

  3. Scroll the screen to see the index metrics.

You can see the following metrics about your index.

  • Document count – The total number of documents indexed. This includes all documents from all data sources. Use this metric to determine if you need to purchase more or fewer storage units for your index.

Use this information to determine how many documents from this data source are included in the index.

  • Document scans – The total number of documents scanned during the sync run. This includes all documents in the data source, including those added, updated, deleted, or unchanged. Use this information to determine if Amazon Kendra is scanning all of the documents in the data source. The number of documents scanned affects the amount charged for the service.
