AWS Integration - DynamoDB

Mackerel supports obtaining and monitoring Amazon DynamoDB metrics in AWS Integration. When integrating with AWS Integration, billable targets are determined using the conversion 1 Table = 1 Host.

Please refer to the following page for AWS Integration configuration methods and a list of supported AWS services.

Obtaining metrics

The metrics obtainable with AWS Integration’s DynamoDB support are as follows. For Metric explanations, refer to the AWS help page.

Metrics per table

SuccessfulRequestLatency SuccessfulRequestLatency dynamodb.successful_request_latency.#.minimum

ReturnedItemCount ReturnedItemCount dynamodb.returned_item_count.#.minimum
dynamodb.returned_item_count.#.average
dynamodb.returned_item_count.#.maximum
float Minimum

RequestCount RequestCount dynamodb.request_count.requests integer SampleCount
  • Among the metrics displayed in Requests, metrics generated for each operation are aggregated and displayed.
  • Similar to UpdateItem, the DynamoDB operation name is actually included in the # of "Mackerel metrics".
  • SuccessfullRequestLatency provides the following two types of information.
    • The elapsed time of successful request(Minimum, Maximum, or Average)
    • The number of successful requests(SampleCount)

Metrics per stream

In addition to the above, the following metrics can be collected when a DynamoDB Stream is enabled for the target table.

Precautions

Among the graphs/metrics obtainable with AWS Integration, metrics included in the following graphs are obtained in 5 minute intervals.

  • ReadCapacityUnits
    • ProvisionedReadCapacityUnits
  • WriteCapacityUnits
