Application Signals now supports burn rate for application performance goals

Amazon CloudWatch Application Signals, an application performance monitoring (APM) feature in CloudWatch, makes it easy to automatically instrument and track application performance against their most important business or service level objectives (SLOs). Customers can now receive alerts when these SLOs reach a critical burn rate. This new feature allows you to calculate how quickly your service is consuming its error budget relative to the SLO's attainment goal. Burn rate metrics provide a clear indication of whether you're meeting, exceeding, or at risk of failing your SLO goals.

Today, with burn rate metrics, you can configure CloudWatch alarms to notify you automatically when your error budget consumption exceeds specified thresholds. This allows for proactive management of service reliability, empowering your teams to take prompt action to achieve long-term performance targets. By setting multiple alarms with varying look-back windows, you can identify sudden error rate spikes and gradual shifts that could affect your error budget.

Burn rates are available in all regions where Application Signals is generally available - 28 commercial AWS Regions except CA West (Calgary) and Asia Pacific (Malaysia) regions.
