如何在AWS CloudWatch中找到DynamoDB表的Throttled Reads图表？

Hey Alex, I’ve dealt with this exact confusion before—let’s break down how to find that Throttled Reads chart you’re looking for:

• Start in the right DynamoDB table view

  1. Open the DynamoDB console, go to the Tables section, and select the table you want to monitor.
  2. Switch to the Monitor tab—this is where all table-specific metrics live by default.

• Add the missing metric to your dashboard
  The default view only shows core capacity metrics, so you’ll need to manually add the throttling metric:

  1. Click the Add metric button in the top-right corner of the Monitor page.
  2. In the metric picker, confirm your target table is selected, then scroll through the metric list to find ThrottledReadRequests (this is the official name for the Throttled Reads metric referenced in the blog).
  3. Check the box next to this metric and click Add to graph—it will immediately appear alongside your existing capacity charts.

• Troubleshoot if the metric still doesn’t show up

  • Verify IAM permissions: Make sure your user/role has the cloudwatch:GetMetricData and cloudwatch:ListMetrics permissions—these are required to pull CloudWatch metrics for DynamoDB.
  • Confirm throttling has occurred: If your table hasn’t experienced any read throttling, the metric might not appear in the list. You can test this by sending a burst of read requests exceeding your table’s provisioned capacity or on-demand throughput limits.

• Alternative: Access directly via CloudWatch
  If you prefer, you can navigate straight to the CloudWatch console:

  1. Go to Metrics > All metrics > DynamoDB > Table metrics.
  2. Locate your table and select the ThrottledReadRequests metric to generate the chart.
