Logging and monitoring in Amazon Cost Management
Monitoring is an important part of maintaining the reliability, availability, and performance of your Amazon account. There are several tools available to monitor your Billing and Cost Management usage.
Amazon Cost and Usage Reports
Amazon Cost and Usage Reports tracks your Amazon usage and provides estimated charges associated with your account. Each report contains line items for each unique combination of Amazon products, usage type, and operation that you use in your Amazon account. You can customize the Amazon Cost and Usage Reports to aggregate the information either by the hour or by the day.
For more information about Amazon Cost and Usage Reports, see the Cost and Usage Report Guide.
Amazon Cost Explorer
Cost Explorer enables you to view and analyze your costs and usage. You can monitor data for up to the last 13 months, forecast how much you're likely to spend for the next three months, and get recommendations for what Reserved Instances to purchase. You can use Cost Explorer to identify areas that need further inquiry and see trends that you can use to understand your costs.
For more information about Cost Explorer, see the Analyzing your costs with Amazon Cost Explorer.
Amazon Budgets
Budgets enables you to track your Amazon cost and usage by using the cost visualization provided by Cost Explorer. Budgets shows the status of your budgets, provides forecasts of your estimated costs, and tracks your Amazon usage, including Free Tier. You can also receive notifications when your estimated costs exceed your budgets.
For more information about Budgets, see the Managing your costs with Amazon Budgets.
