CloudWatch Logs integration – You can query and filter for logs through the CloudWatch Synthetics console. Each log message contains unique
canaryRunId, making it easy to search for logs for a particular canary run. -
Metrics and canary artifacts – You can monitor canary run pass rate through CloudWatch metrics, and configure alarms to alert you when canaries detect issues.
-
Screenshots and steps association – You can capture screenshots using native Playwright functionality to visualize the stages of a canary script on each run. Screenshots are automatically associated with canary steps, and are uploaded to Amazon S3 buckets.
-
Multiple tabs– You can create canaries that open multiple browser tabs, and access screenshots from each tab. You can create multi-tab and multi-step user workflows in Synthetics.
