AWS App Runner now adds service level metrics for CPU utilization, Compute Memory utilization, and the total number of concurrent requests served by the App Runner service in the App Runner console and Amazon CloudWatch. App Runner makes it easier for developers to quickly deploy containerized web applications and APIs to the cloud, at scale, and without managing infrastructure. Earlier, you could only view the CPU and memory utilization at application instance level. Now, you can view all these metrics at your App Runner service level. You can use these metrics to optimize your App Runner service’s auto-scaling configuration by analyzing the CPU and Memory utilization for the concurrent requests served by your service.
