Amazon CloudWatch Synthetics now supports prebuilt canary monitoring dashboard
When using CloudWatch Synthetics, you can now get a snapshot of the canary health with a prebuilt monitoring dashboard. The new monitoring dashboard provides canary data trends over time for latency, availability, and error counts. The dashboard also provides expected latency based on historical data of the previous canary runs. This helps you spot anomalies sooner which in turn allows you to respond faster to ensure a better end user experience.
