What is Synthetic Monitoring?

Synthetic monitoring simulates user interactions with your application to proactively detect issues. Unlike real user monitoring (RUM), synthetic monitoring runs automated tests on a schedule, allowing you to:

• Catch issues before users do - Detect problems during off-hours or low-traffic periods
• Test from multiple locations - Verify performance from different geographic regions
• Monitor critical user flows - Ensure login, checkout, and other key paths work correctly
• Track performance trends - Identify degradation before it impacts users

Core Features

Browser Journeys

Record and replay multi-step user flows using Playwright. Test login flows, checkout processes, form submissions, and more.

// Example journey step
await page.goto('https://app.example.com/login');
await page.fill('#email', '[email protected]');
await page.fill('#password', 'password');
await page.click('button[type="submit"]');
await expect(page.locator('.dashboard')).toBeVisible();

Uptime Monitoring

Monitor availability and performance across multiple protocols:

• URL Monitors - HTTP/HTTPS endpoint checks with status and body assertions
• API Monitors - Multi-step API workflows with variable extraction
• TCP Monitors - Port connectivity and TLS certificate monitoring
• DNS Monitors - DNS record validation (A, AAAA, CNAME, MX)
• Heartbeat Monitors - Ping-based monitoring for cron jobs and services

Smart Alerts

Configure intelligent alerts with multiple channels:

• Slack notifications
• Email alerts
• Webhook integrations
• Microsoft Teams

Set up alert rules based on:

• Consecutive failures
• Error rate thresholds
• Latency thresholds
• Visual diff detection
