Datadog-AWS DynamoDB Integration

DynamoDB default dashboard

Overview

Amazon DynamoDB is a fully managed NoSQL database cloud service, part of the AWS portfolio. Fast and easily scalable, it is meant to serve applications which require very low latency, even when dealing with large amounts of data. It supports both document and key-value store models, and has properties of both a database and a distributed hash table.

Learn more about how to monitor DynamoDB performance metrics thanks to our series of posts. We detail the key performance metrics, how to collect them, and how Medium monitors DynamoDB using Datadog.

Setup

Installation

This integration requires the permissions dynamodb:list* and dynamodb:describe* to be fully enabled.
