Website monitoring is the process of testing or tracking (monitoring) how end-users interact with a website or web application. Website monitoring is often used by businesses to ensure that their customers are able to access their online applications and perform actions such as searching, online shopping, checking an account balance, or simply researching.
By monitoring website and web application performance, IT Departments or Network Engineers hope to avoid downtime and keep their applications running. Commonly measured metrics are response time and availability (or uptime), although both consistency and reliability metrics are starting to gain popularity.
Website monitoring can be done from both inside and outside of a corporate firewall. Traditional Network Management solutions focus on inside the firewall monitoring, whereas external performance monitoring will test and monitor performance issues across the Internet backbone and in some cases all the way to the end-user. External performance monitoring is also known as end-user monitoring or end-to-end performance monitoring.
Website monitoring service can check HTTP pages, HTTPS, FTP, SMTP, POP3, IMAP, DNS, Telnet, SSL, TCP and a range of other ports with great variety of check intervals from every 4 hours to every one minute. Typically, most website monitoring services test your server anywhere between once-per hour to once-per-minute.
Website monitoring services usually have a number of servers around the globe - USA, Europe, Asia, Australia and other locations. By having multiple servers in different geographic locations, monitoring service can determine if a Web server is available across different Networks worldwide. The more locations the better picture on your website availability.
