New Relic now offers an integration with AWS Trusted Advisor. AWS establishes limits for each service in each account and region. Some examples are: number of Auto Scaling groups, number of EBS active volumes, and number of EC2 elastic IP addresses. AWS recommends watching these limits, and even allows you to enable automated actions and custom notifications. That data is now also available in New Relic.
New Relic now offers a cloud integration with the Azure Cost Management service. It provides the accumulated costs in the billing period, grouped by cloud service, resource group, region and (if configured) custom tags.
