What is Synthetic Monitoring?
Synthetic Monitoring—sometimes called active monitoring—is a technique used by IT teams and digital businesses to proactively test website, application, and API performance. Unlike passive monitoring (which relies on real user activity), synthetic monitoring simulates user interactions with your digital assets from various locations and at scheduled intervals. It acts like a robot visiting your website or app, running scripted transactions such as loading pages, clicking buttons, filling forms, and making API calls—even when no real users are online.
Synthetic monitoring helps businesses identify problems before real users are impacted. It answers questions such as:
- Are all critical flows on our website working 24/7?
- Is our service available globally?
- How fast are pages loading from different cities or countries?
- Are our third-party dependencies (like payment gateways) up and running?
Key takeaway: Synthetic monitoring is your 24/7 digital watchdog, always on the lookout for potential issues, so you can deliver a seamless user experience.
Major Advantages of Using Synthetic Monitoring Tools
Synthetic monitoring tools offer unique and powerful advantages over relying solely on real-user data. Here are the top reasons why organizations depend on them:
| Advantage | Description |
|---|---|
| Proactive Issue Detection | Identify outages, slowdowns, and transaction failures before users are affected. |
| Global Reach | Test from multiple global locations, ensuring performance for users everywhere. |
| Continuous Uptime Monitoring | Monitor 24/7, even during periods of low or no user traffic. |
| End-to-End User Journey Testing | Validate complex workflows (e.g., checkout, login, search) across your apps. |
| Benchmarking & SLA Validation | Measure your service levels and compliance against SLAs, and benchmark versus competitors. |
| Third-Party Dependency Testing | Test APIs and third-party services, alerting you if integrations break or degrade. |
| Faster Troubleshooting | Receive detailed error data and screenshots for rapid root-cause analysis. |
| Performance Baselines | Establish performance benchmarks and track changes after code deployments or infrastructure changes. |

| Geographic Coverage | Ability to test from multiple countries, continents, or cities, to reveal region-specific issues. |
| API Monitoring | Test REST, SOAP, and GraphQL endpoints, including chained requests and assertions. |
| Mobile & Browser Testing | Emulate real browsers (Chrome, Firefox, etc.) and mobile devices to catch rendering or compatibility problems. |
| Custom Scripting | Support for advanced scripting (e.g., Selenium, JavaScript) to mimic real user behavior and handle edge cases. |
| Alerting & Notifications | Customizable alerts via email, SMS, Slack, webhooks, and integrations with incident management tools. |
| Detailed Reporting & Dashboards | Interactive dashboards, trend charts, and historical performance data for analysis and reporting. |
| Root Cause Diagnostics | Capture of error messages, screenshots, HAR files, and network traces for faster troubleshooting. |
| Maintenance Windows | Suppress alerts during planned downtime to avoid noise. |
| Integration with Other Tools | Connect with APM, incident management, DevOps pipelines, and CI/CD tools for complete visibility. |
