How PRTG will help you with HTTP monitoring
How PRTG defines sensors
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
Quickly find the root cause of HTTP errors
Are your customers or employees complaining that a website or service feels slow? This can be caused by a number of factors, like a connectivity issue on their end, an unusually high server load, or not enough bandwidth resources, for example.
Before you can determine the root cause of the issue, you first need to assess the symptoms. Is the web page really that slow? How much time does it need to load? To get the answers you need, use the HTTP v2 sensor in Paessler PRTG to precisely measure the load time of a web page, and analyze dependencies to see if the problem stems from your web server or perhaps your hosting provider
See your web server status at a glance
It is not enough to know if your web server is up or down. To ensure performance and availability, you need more information like the CPU load on the web server, how many resources are available to handle incoming requests, the number of requests per second, and more.
If you run an Apache web server, for example, you can get all these metrics with the HTTP Apache ModStatus PerfStats sensor. Combine it with the HTTP Apache ModStatus Totals sensor to get additional data like the total number of accesses or the amount of data transferred in a given time period.
Get global HTTP monitoring without effort
Due to the complex routing nature of the internet, a website that is reachable from your physical location may be unavailable from somewhere else in the world, which can result in service outages and revenue loss from customers in the affected region.
To ensure worldwide availability of your websites and get timely alerts in case of interruptions, you can use the Cloud HTTP v2 sensor. This sensor monitors the loading times and availability of a web page from four continents around the globe. You set the URL that you want to monitor, provide the source locations, and PRTG does the rest for you.
Custom monitoring of IoT devices & more
You can use HTTP to push data from IoT devices to PRTG and use our various push sensors to process and display this information. In fact, we used Sigfox-enabled hardware sensors and the HTTP IoT Push Data Advanced sensor of PRTG to build a custom environmental monitoring solution for our Paessler headquarters in Nuremberg.
To monitor the source code of a web page, you can use the HTTP Advanced sensor. This flexible sensor supports authentication and content checks. You can set it to trigger a notification if the content of a HTML file changes, for example, or to alert you if a specific keyword is present or missing.

3 reasons why to choose PRTG as your HTTP monitoring tool
High flexibility & versatility
PRTG comes with more than 250 preconfigured sensors for a variety of use cases, services, and devices from the most popular manufacturers and providers. With our PRTG web server (HTTP) sensors, for example, you can monitor HTTP response codes, load times, HTTP server performance statistics, and more.
Great observability & visualization
PRTG provides you with one central monitoring solution for all your needs, be it your HTTP content, your web servers – or your entire network. Enjoy a quick overview of your whole IT infrastructure via our different user interfaces for web, desktop, or smartphone, and create custom dashboards with our easy-to-use drag-and-drop editor.
All-in-one web monitoring
With our PRTG HTTP monitor, you can do all kinds of HTTP monitoring: availability monitoring (Is my web server up and running?), HTTP content monitoring (Are there unwanted HTML content changes?), web server performance monitoring (How are response and load times of my web pages?) and even HTTP/S security monitoring (Are my SSL certificates still valid?).
Professional HTTP monitoring enhances user satisfaction & saves money
The Hypertext Transfer Protocol, or HTTP, is one of the basic internet technologies. Every time a customer visits your website to browse the product catalog, place an order, or interact with customer service, this is done via a web browser that speaks HTTP(S) with your web server. Ensuring that your servers are available, perform well, and that content is delivered in the shortest time possible, is crucial for the success of your business.
PRTG helps you to…
- Get early notifications about errors with customizable alerts
- Gain insights into web server performance and website availability
- Simplify web management with one monitoring tool that covers all your needs
What’s more:
There is no need to invest in different monitoring tools from multiple vendors when you can do it all with our HTTP monitor PRTG – and thus save effort and costs.

HTTP monitoring: FAQ
1. What is an HTTP monitor?
The term HTTP Monitor can have various meanings. You can use it for a software that can monitor and analyze the performance and behavior of HTTP connections, like those between web servers and clients (web browsers) that communicate through the Hypertext Transfer Protocol (HTTP). It can also be applied to tools that are used to monitor the parameters of an HTTP server, for example, uptime, system load, or available resources, on an Apache HTTP Server instance.
In both of these contexts, HTTP monitoring tools can be used to assess server availability and content delivery performance, ensuring that the users who visit your websites have the best experience possible. However, the term can also be loosely applied to tools that use HTTP to monitor something else. For example, a tool that uses HTTP to fetch content from a server and acts on that information.
In the end, it doesn't matter how you define HTTP monitoring: PRTG has a sensor for every HTTP monitoring task.
2. Why is HTTP monitoring important?
There are different reasons why it is a good thing to invest in an HTTP monitoring software, for example:
- Better availability: an automated monitoring tool can quickly alert your staff about server outages or other issues, which gives them crucial time to remediate the problem before your customers notice.
- More security: HTTP monitoring can detect repeated, suspicious, or unusual requests that may be symptoms of an attempt of a data breach or of unauthorized access.
- Performance optimization: an HTTP monitor can help you detect issues such as slow response and load times, identify the cause, and develop and validate a solution.
- Capacity planning: constant monitoring enables you to set up a baseline of the performance of your servers and content, and predict future capacity needs as your network grows.
- User experience: by monitoring server response codes, you can detect and address issues that could impact user satisfaction, such as unavailable content or broken links.
3. What do I look for when choosing an HTTP monitoring tool?
There are 5 main features you need to look out for when you choose an HTTP monitoring tool. With PRTG, you get all of them:
- The capability to monitor many aspects of your HTTP infrastructure in one tool
- A centralized display of information from many sensors for better observability
