Overview of website monitoring

What is website monitoring?

Website monitoring is a practice to ensure the availability, performance, and security of a website or web application. Website monitoring measures the end-user experience that a webpage provides and offers visibility into various metrics that can affect performance and availability.

Is website monitoring important for customer retention?

Yes, a glitch-free and trusted online experience is what every customer is looking forward to. It is said that the performance of a website is directly proportional to the rate of customer conversion, revenue, and end-user satisfaction. A slow loading page can lead to creating a bunch of dissatisfied customers who might leave your page in search of a fast loading, better performing web page. With web performance monitoring, fine-tune the performance of your page elements, ensure a better load time, and retain your customer base.

What types of website monitoring does Site24x7 support?

Site24x7 supports multiple types of website monitoring, including:

  • Uptime monitoring at regular frequencies to track site availability.
  • Webpage speed monitoring to track page performance, load times , web vitals, CDN performance, and more.
  • Synthetic monitoring that simulates user interactions in multi-step workflows and critical business processes for proactive issue detection.
  • Real user monitoring (RUM) to analyze the actual user experience.
  • Website security monitoring for tracking SSL certificate expiries, domain expiry, blocklist monitoring, and more to prevent service disruptions.
How does Site24x7 verify an outage and avoid false positives?

Site24x7 verifies outages and avoids false positives by performing multi-location checks by applying the majority rule, automatically rechecking failures from secondary locations before alerting, allowing configurable thresholds for consecutive failures, and using location failover and dependency mapping to suppress alerts caused by upstream or related issues, ensuring reliable and precise outage detection.

Which geographies and locations can I run checks from?

With Site24x7, you can run website checks from over 130 global monitoring locations across regions, including the Americas, Europe, Asia, Africa, and Australia. You can select locations that match your user base and set a primary location for SLA calculations while checking availability from multiple other locations to validate regional performance and uptime. Additionally, Site24x7 supports private monitoring via On-Premise Pollers, allowing you to monitor internal networks or private clouds behind firewalls. This comprehensive global coverage ensures precise, region-specific insights and robust uptime verification for your digital services.

What intervals and timeouts can I configure?

You can configure monitoring intervals based on your requirements, and they commonly range from 1 minute to 15 minutes or longer, say one, three, five, 10, 15, 20, or 30 minutes; one hour; or one day. Request timeouts are typically configurable per monitor, allowing you to tailor how long Site24x7 waits for a response before considering the check failed. Polling options such as 10 or 30 seconds are available to track issues more proactively. These customizable intervals and timeouts help balance monitoring accuracy, resource utilization, and alert responsiveness to fit your organization’s monitoring strategy.

Can Site24x7 monitor sites behind a firewall or on private networks?

Site24x7 can monitor websites or services behind the firewall or within private networks using an On-Premise Poller. The On-Premise Poller initiates secure outbound connections to the Site24x7 cloud platform, so typically, you only need to allow outbound traffic from your network, simplifying firewall configurations while maintaining strong security. This solution ensures comprehensive monitoring coverage of internal systems alongside your public-facing assets, helping you maintain visibility and uptime across your entire IT environment.

Which HTTP features and methods are supported?

Site24x7 supports multiple HTTP features and methods. It supports HTTP/HTTPS protocols, including handling redirects and custom ports. To simulate various requests, you can configure HTTP methods like GET, POST, PUT, and DELETE. Site24x7 also adds custom headers and cookies, enabling accurate emulation of real client requests. This rich feature set enables thorough monitoring and validation of web endpoints' availability, functionality, and security.

Can I monitor SSL/TLS certificates and get expiry alerts?

Site24x7 allows you to monitor SSL/TLS certificates by validating the hostname, expiry date, and certificate chain from multiple global locations.

It performs various checks, including certificate validity, certificate revocation, and SHA-1 fingerprint to identify tampering, and verifies whether the certifying authority is blocklisted. This helps ensure your website maintains a secure and trustworthy environment for visitors.

You can configure proactive alerts in Site24x7 to notify you well before your SSL/TLS certificates expire, and also get alerts for validation issues such as hostname mismatches or invalid chains.

How are alerts delivered and routed?

You can stay up to date on status updates from Site24x7 through various notification modes, including email, SMS, voice calls, mobile push notifications, and popular chat tools like Slack and Microsoft Teams. Integration with incident management platforms such as PagerDuty and Opsgenie, IT service management tools like ServiceNow and Jira, and custom webhooks are also supported. This flexibility ensures that alerts reach the right people quickly and through the most effective means.

Alerts can be routed and escalated based on configured policies, including severity levels, tags, and monitor groups.
