Amazon CloudWatch Synthetics, an outside-in monitoring capability to continually verify your customers’ experience using snippets of code called canaries, is extending historical data for canary runs that pass or fail from 7-days to 30-days. Canary run troubleshooting artifacts such as screenshots from the canary run, HAR files, and log files for historical runs can be viewed for up to 30 days to easily pin point persistent versus intermittent canary run failure patterns on the CloudWatch console.
