Synthetic Monitoring Maintenance overview

Maintains and evolves the suite of synthetic monitors (canary tests, uptime checks, transaction monitors) — reviewing which critical user journeys are covered, updating selectors and API contracts broken by recent deploys, tuning alert thresholds to reduce false-positive noise, rotating test credentials, validating multi-region probe distribution, and retiring monitors for deprecated features. Produces a synthetic-monitor inventory with coverage and health status. Excludes production incident response.
