Synthetic Monitoring
Synthetic monitoring proactively simulates user interactions against a service from controlled locations, rather than waiting for real users to hit a problem.
Where real user monitoring observes actual visitors, synthetic monitoring runs scripted checks — from a simple HTTP request to a full browser flow (login, search, checkout) executed by a headless browser. It catches problems before customers do, even on low-traffic pages.
Because synthetic checks run on a fixed schedule from known locations, they give clean, comparable data over time and are ideal for SLAs, performance baselines, and critical-path testing.
