Introduction

Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability.

DynamoDB features include:

  • Administrative offloading, which reduces the burden of operating and scaling a distributed database as well as hardware provisioning, setup, and configuration, replication, software patching, or cluster scaling.
  • Encryption at rest, which eliminates the operational burden and complexity involved in protecting sensitive data.

Setup

To set up the OpsRamp AWS integration and discover the AWS service, go to AWS Integration Discovery Profile and select DynamoDB.

aws_dynamodb_ThrottledRequestsThrottledRequestsCountSUMNumber of user requests that exceeded the preset provisioned throughput limits in the specified time period.
aws_dynamodb_ReadThrottleEventsReadThrottleEventsCountSUMNumber of read events that exceeded the preset provisioned throughput limits in the specified time period.
aws_dynamodb_WriteThrottleEventsWriteThrottleEventsCountSUMNumber of write events that exceeded the preset provisioned throughput limits in the specified time period.
aws_dynamodb_ProvisionedReadCapacityUnitsProvisionedReadCapacityUnitsCountAVERAGENumber of provisioned read capacity units for a table or a global secondary index.
aws_dynamodb_ProvisionedWriteCapacityUnitsProvisionedWriteCapacityUnitsCountAVERAGENumber of provisioned write capacity units for a table or a global secondary index.
aws_dynamodb_ConsumedReadCapacityUnitsConsumedReadCapacityUnitsCountAVERAGENumber of read capacity units consumed over the specified time period. Use this metric to track how much of provisioned throughput is used. Also, use this metric to retrieve the total consumed read capacity for either a table and all of its global secondary indexes or a particular global secondary index.
aws_dynamodb_ConsumedWriteCapacityUnitsConsumedWriteCapacityUnitsCountAVERAGENumber of write capacity units consumed over the specified time period. Use this metric to track how much of provisioned throughput is used. Also, use this metric to retrieve the total consumed write capacity for either a table and all of its global secondary indexes or a particular global secondary index.
aws_dynamodb_ReturnedItemCountReturnedItemCountCountAVERAGENumber of items returned by a Scan or Query operation.
aws_dynamodb_SuccessfulRequestLatencySuccessfulRequestLatencymsAVERAGENumber of successful requests in the specified time period.
