Remediation via AWS Console

1. Log in to the AWS Management Console and open the Amazon DynamoDB console.

   
2. In the left navigation panel, click Tables and select the affected DynamoDB table.
3. Open the Monitor tab.

Monitoring via AWS CLI

1. Log in to the AWS Management Console and click the CloudShell icon (>_) in the top-right corner.

   

2. Describe DynamoDB tables in the region:

   

   aws dynamodb list-tables
   

3. Monitor read capacity using CloudWatch metrics:

   

   aws cloudwatch get-metric-statistics \
    --namespace AWS/DynamoDB \
    --metric-name ConsumedReadCapacityUnits \
    --dimensions Name=TableName,Value=<table-name> \
    --statistics Sum \
    --period 300 \
    --start-time $(date -u -d '15 minutes ago' +%Y-%m-%dT%H:%M:%SZ) \
    --end-time $(date -u +%Y-%m-%dT%H:%M:%SZ)
   

Regularly review read capacity metrics and configure CloudWatch alarms to proactively detect throttling or abnormal usage patterns.
