We are excited to announce that you can now add horizontal annotations to your graphs and dashboards in CloudWatch.
Horizontal annotations can serve as quick visual checks of metrics crossing pre-defined values, such as SLA limits, or provide contextual information for interpreting metric values. You can add lines at key values on the Y-axis, and optionally shade areas between the lines, so that you can analyze your graphed metrics at a glance.
To get started, you can add horizontal annotations via the AWS Management Console or programmatically add them using Dashboards APIs via the AWS Command Line Interface (CLI) and AWS SDKs.
