A server checker (often referred to as a Server Status Checker or Uptime Monitor) is a tool used to verify whether a server, website, or network service is active, responsive, and functioning correctly. These tools can range from simple web-based utilities to comprehensive, automated enterprise monitoring platforms. Primary Functions of a Server Checker
Availability Checks (Uptime): Verifies if a server is online (“Up”) or offline (“Down”).
Latency Measurement: Tracks the time it takes (in milliseconds) for a server to respond to a request.
Protocol Testing: Evaluates specific connection protocols like HTTP/HTTPS for websites, TCP/UDP for open network ports, or DNS for domain routing.
Global Probing: Tests server responsiveness from multiple geographic locations to pinpoint regional outages or CDN latency issues. Common Types of Server Checkers Check server : Check host – online website monitoring
