Host-Tracker
Host Tracker is a website and server monitoring service that checks the availability and performance of web resources around the clock from a global network of monitoring agents. Regular checks help detect and resolve problems such as downtime, slow page loads, broken links, and server errors before they affect users.
Availability checks use protocols including HTTP(S), ICMP (ping), SMTP, SNMP, and TCP. Content monitoring confirms that specific page elements are present and working correctly. Transaction monitoring reproduces multi-step scenarios such as form submissions and site navigation to catch functional failures. Blacklist monitoring warns when a domain or IP appears on DNS-based blacklists that can hurt email deliverability and search rankings.
When an issue is detected, Host Tracker notifies the responsible people through multiple channels: email, SMS, voice call, Telegram, Viber, Slack, and web push. The service also compiles uptime statistics and performance reports in PDF, CSV, and XML formats.
Additional tools include domain and SSL certificate expiration monitoring, page speed analysis, database performance checks, and server resource monitoring (CPU, RAM, disk load), giving a complete view of a site's health and performance.
