Springwinter reads CloudWatch metrics directly from your AWS account and displays CPU utilization, memory utilization, request rate, and error counts for each running service. The metrics dashboard gives you a real-time view of service health without requiring you to open the AWS Console or configure any additional monitoring tools.

​
Available Metrics by Resource Type

Different resource types expose different CloudWatch metric dimensions. Here is what Springwinter surfaces for each.

Web Servers

ECS + ALB metrics
  • CPU utilization (%)
  • Memory utilization (%)
  • Request count
  • Error rate (4xx and 5xx responses)

Workers

ECS metrics
  • CPU utilization (%)
  • Memory utilization (%)
  • Running task count

Caches

ElastiCache metrics
  • Cache hits and misses
  • Memory used (bytes)
  • Active connections

Static Websites

CloudFront + S3 metrics
  • Request count
  • Bytes transferred
  • Error rate

Storage

S3 metrics
  • Number of objects
  • Bucket size (bytes)
  • Request count

​
Viewing Metrics in the Dashboard

1

Open the resource

Navigate to your project and click on the resource you want to monitor — a web server, worker, cache, static website, or storage bucket.
2

Select the Metrics tab

Click the Metrics tab on the resource detail page. Charts for all available dimensions load automatically.
3

Adjust the time range

Use the time range selector to zoom in on a specific window, such as the last hour, last 24 hours, or last 7 days.

​
Metrics API

Fetch raw metric data programmatically for dashboards, alerting integrations, or automated runbooks.

Metrics are read live from CloudWatch and appear only once a resource is running and CloudWatch has begun collecting data. A newly deployed service may show no data for the first few minutes while the first metric points accumulate.
