4 ways PRTG makes HTTP monitoring easy
Quickly find the root cause of HTTP errors
Are your customers or employees complaining about a slow website or service? This can be caused by a connectivity issue on their end, an unusually high server load, or not enough bandwidth resources.
To determine the root cause of the issue, you must assess the symptoms. Is the web page really that slow? How much time does it need to load? It’s easy to get the answers with the HTTP v2 sensor included with PRTG.
It helps you precisely measure the load time of a web page and analyze dependencies to see if the problem stems from your web server or 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 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.
Easily get global HTTP monitoring
The complex routing nature of the internet means a website that is reachable from your physical location may be unavailable elsewhere in the world, which can result in service outages and revenue loss from customers in the affected region.
Avoid costly downtime, ensure worldwide availability of your websites, and get timely alerts of interruptions by using 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 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.
What HTTP website monitoring looks like in PRTG
Diagnose network issues by continuously tracking your web services, web servers, web applications, websites, and other endpoints via HTTP. Show web performance and availability, response times, HTTP status codes, DNS resolution, SSL certificate expiration dates, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot HTTP issues.

HTTP monitoring: FAQ
What is HTTP?
HTTP stands for Hypertext Transfer Protocol. It is the foundational communication protocol used on the World Wide Web to transfer data between a client (such as a web browser) and a server. HTTP enables the fetching of resources, such as HTML documents, images, videos, and other files, from a server to display on a user's device.
How it works
-
Client request: A client sends an HTTP request to the server, typically by entering a URL in a browser or clicking a link.
-
Server response: The server processes the request and sends back an HTTP response containing the requested resource or an error message.
HTTP methods
Each HTTP transaction consists of:
-
Request: Includes methods like GET, (fetch data), POST (send data), PUT (update data), or DELETE (delete data).
-
Response: Contains a status code (for example, 200 OK, 404 Not Found), headers, and the requested response body content.
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.
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.
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

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.
