Monitoring web servers: FAQ
What is a web server?
A web server is a software or hardware system that serves content to users over the web. Its primary role is to deliver web pages and other web resources to clients (like web browsers) when requested, typically through the Hypertext Transfer Protocol (HTTP).
Examples of web server software:
- Apache HTTP server: Popular, open-source web server known for flexibility.
- Nginx: Lightweight, high-performance server often used for reverse proxy and load balancing.
- Microsoft IIS (Internet Information Services): Used with Windows Server.
What is web server monitoring?
Web server monitoring is the backstage pass to your website. Websites, applications, and services running on your server stay online, fast, and secure. Monitor server metrics like memory usage, uptime, disk space, network traffic, CPU, and even SSL certificate health in real time, and catch performance issues before anyone notices them. With PRTG's monitoring solution, you get a heads-up if response time drags, ensuring a great user experience, top-notch server performance, and minimal downtime.
Why should I care about web server monitoring?
Web server monitoring ensures your server is online, fast, and secure. Without it, you’re flying blind – only finding out about problems when your users do. With a tool like PRTG, you get 24/7 visibility, instant alerts, and the power to keep your server healthy, fast, and running smoothly.
If you want to avoid surprise outages, prevent slowdowns, and keep your users happy, web server monitoring is a must. Don’t wait for users to tell you something’s broken – know it before they do.
Which web servers can PRTG monitor?
PRTG comes with out-of-the-box monitoring for Apache web servers and Microsoft IIS. With its custom sensors and API requests, however, you can practically monitor every web server you can think of. For NGINX web server monitoring, for example, you can find a how-to guide in our Knowledge Base.
What is a sensor in PRTG?
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.
On average, you need about 5-10 sensors per device or one sensor per switch port.
