![]() ![]() NGINXĭespite only being released in 2004, NGINX is one of the top competitors to Apache. Newer versions are much more effective at handling heavy traffic but may need additional tuning. This allowed it to respond quickly to incoming requests but made it impossible to handle a large number of requests at once. Originally, Apache spawned a new thread for each new connection. Apache’s biggest challenge is its scalability. This model-along with an active development community and extensive list of supported modules-makes Apache extremely versatile. Its architecture has a base core with additional features added through modules. As of October 2018, it’s used to host over 45% of all websites.Īs an open-source project, Apache is both freely available and widely customizable. It was created in 1995 and quickly grew in popularity. The Apache HTTP Server (also called httpd or Apache) is the world’s most popular web server. There are dozens of web servers, but the two most popular are Apache and NGINX. This data can help you develop plans for scaling your website, optimizing your application, or deploying other services to support the increased demand. This data is particularly valuable in a world where more users are using ad blockers, preventing tracking through JavaScript. Traffic and connection metrics offer direct insight into site activity, including the number of active users and the duration of each session. Lastly, monitoring helps track the popularity and growth of websites and web applications. To do this, the load balancer must be aware of each web server’s current load and its availability to handle new requests. A separate load balancing service receives incoming requests, checks the availability of the web servers located behind it, and proxies the request to an available server. High-availability environments often optimize throughput with load balancing, where requests are delegated across multiple web servers rather than to a single one. Monitoring has a second benefit for IT environments: automation. Additionally, monitoring will alert you to any errors or failures that could result in downtime. This applies to large sites as well the BBC found that for every one-second increase in page load time, 10% of their users left. If your web servers are slow, users will abandon your service for a competitor’s. Since web servers handle user requests for content, their performance has an immediate and noticeable impact on the user experience. Availability of other web servers for proxying requests.Traffic being transferred to and from the server at any given time.Requests for host resources such as CPU, RAM, and disk access.Connections to clients and other servers on the network.This means there’s much to keep track of, including: Web servers provide a number of important functions. At the core of each of these transactions is the Hypertext Transfer Protocol (or HTTP), a nearly 30-year-old protocol that defines how web traffic is structured and handled. Proxies are used to redirect requests from one web server to another based on a set of rules. Dynamic content is used in websites where the content changes based on the request. Web servers also perform other services, such as serving dynamically generated content to activating as a forward or reverse proxy. This basic interaction defines every connection made between your computer and the websites you visit. Devices that are networked to the server (clients) request these resources, and the server delivers them. ![]() These resources can be anything from HTML documents to music files to JavaScript files. Web servers are software services that serve resources over the World Wide Web. And with the cloud computing craze moving more services online, web servers, and web server monitoring as a result, are only becoming more important. Social networking, media streaming, software as a service (SaaS), and other activities wouldn’t be possible without the use of web servers. They host the websites, web services, and web applications that we use on a daily basis. In addition even basic/trivial web site monitoring services allow you to define additional URL's to check.Ĭonsider setting up a (password protected) monitoring area on your website where you can deploy trivial web services for such custom monitoring.Web servers are among the most important components in modern IT infrastructures. Install the agent and you should get many useful metrics.Many monitoring services support and provide agents to monitor all kinds of properties on your servers as well as custom checks for things/metrics they don't support natively already. ![]()
