CloudWatch Synthetics Canaries are automated scripts that you create to monitor the availability, performance, and functionality of your web applications, APIs, and other internet-facing resources. These scripts simulate real user interactions, allowing you to proactively identify and address issues before they impact your customers.
Key Concepts:
- Canaries: These are the automated scripts that perform the monitoring tasks. They can be written in JavaScript or Python.
- Endpoints: The URLs or APIs that your Canaries interact with.
- Schedules: You define how often the Canaries should run, such as every minute, hour, or day.
- Alerts: You can configure alerts to be triggered when a Canary fails or encounters performance issues.
- Visual Monitoring: Canaries can capture screenshots of web pages and compare them to baselines to detect visual changes.
How Canaries Work:
- Creation: You create a Canary script, specifying the endpoint to monitor and the actions to perform.
- Scheduling: You define a schedule for the Canary to run.
- Execution: The Canary runs according to the schedule, simulating user interactions with the endpoint.
- Monitoring: The Canary monitors various aspects, such as response times, error rates, and visual changes.
- Alerting: If the Canary detects any issues, it triggers an alert, notifying you of the problem.
