PREMIUM MONITORS
Go Beyond Uptime Monitoring
An uptime check confirms a service responded. It doesn't tell you if a real visitor had a smooth experience, or if your checkout flow actually completed. RUM and Synthetic Monitoring, two premium monitoring solutions, close that gap: one watches real traffic as it happens, the other rehearses real journeys before customers hit them.
Real User Monitoring (RUM)
Real User Monitoring records how actual visitors experience your site: load speed, layout shifts, and script errors, captured straight from their browsers instead of a lab test.
Real-time monitoring tracks Core Web Vitals from live visitor sessions
Captures client-side JavaScript errors as they happen
Compares load times across regions, networks, and browsers
Flags slow-loading resources and API calls in the browser
- Explore RUM
Synthetic Monitoring
Synthetic Monitoring runs scripted visits to your site on a schedule—a login, a signup, or a checkout—so you catch a broken flow before a customer does.
Tests multi-step journeys before customers encounter failures
Runs scheduled checks from global monitoring locations
Catches broken checkout, login, and signup flows
Validates critical paths with consistent test conditions

FAQ
Quick Answers About the Uptime Monitoring Platform
What is uptime monitoring?
Uptime monitoring is the process of using monitoring software to check whether websites, APIs, servers, ports, SSL certificates, and other services are online and responding. It helps teams detect downtime early, route alerts, and track response times.
What does the Zunoy uptime monitoring hub include?
Zunoy has dedicated pages for HTTPS, keyword, ping, port, SSL, heartbeat, domain, DNS, API, TCP, UDP, IPv4, IPv6, website, response time, page speed, cron job, synthetic, browser script, browser flow, API chain, blacklist and email deliverability, visual ping, and manual monitoring. This provides targeted documentation for each of our monitoring services.
How many monitoring locations does Zunoy support?
Zunoy operates 10 global monitoring regions, checking your services from nodes across Mumbai, Bengaluru, San Francisco, N. California, New York, London, Paris, Frankfurt, Toronto, and Tokyo to ensure broad geographic availability.
When does an alert trigger?
Alerts trigger based on your monitor sensitivity settings. You can configure a check to trigger an alert after 1, 2, or 3 consecutive failures to balance fast detection against unnecessary noise.
Can failed monitors create incidents automatically?
Yes. Failed checks can create incidents automatically based on your alert routing rules, allowing responders to track ownership, status, comments, and SLA impact in a single timeline.
How do I choose the right monitor type?
Choose between different types of uptime monitoring tools based on the failure you want to prevent. Use HTTPS for web endpoints, ping for reachability, SSL for certificate expiration, heartbeat for background processes, API for backend responses, and synthetic checks for user flows.
What check intervals does Zunoy support?
Zunoy supports monitor check intervals from 30 seconds to 60 minutes, including 30s, 1 min, 2 min, 5 min, 10 min, 15 min, 30 min, and 60 min. The available check frequency depends on your chosen plan.
Which alert channels does Zunoy support?
Zunoy supports 10 alert channels, including email, SMS, Slack, webhooks, Microsoft Teams, Discord, phone, Telegram, n8n, and Zapier. The n8n and Zapier integrations allow teams to build custom alert workflows.
What does the free plan include?
Zunoy's free plan includes up to 10 monitors, 3 team members, and 1 workspace. It also includes 5-minute check intervals, a public status page, and incident management.
Can monitor data appear on a status page?
Yes. Uptime percentages, latency charts, incident history, and current status can be synced to public or private status pages automatically.
