Profit from Reliable Website Monitoring as a Company

Companies and organizations are highly dependent on their web presence, with which they provide information, advertise and sell products. Today, a high-performance, dependable website is a critical success factor. It is important for network administrators to know the status of their web presence in order to guarantee availability. PRTG Network Monitor continuously monitors website status and availability, delivers long-term analyses to optimize performance and executes alarms to notify administrators of failures or poor website availability.

A comprehensive monitoring solution can be used in various ways:

  • Profit maximization by avoiding losses due to undetected web presence failures
  • Improved customer satisfaction by guaranteeing 100% uptime as well as fast, reliable access to the website
  • Increased staff productivity through high performance and failure-free intranet

The website monitoring solution PRTG is optimized for simple installation and usage. Additional functions, including web browser or organizer access and alarms for failures or website access problems via email, ICQ, pager or text message simplify web presence monitoring. PRTG is optimized for websites of companies and to monitor Startups likewise.

Detailed Website Monitoring

PRTG Network Monitor is the high performance solution for monitoring networks and websites created by Paessler AG in Nuremberg. With this comprehensive website monitoring services, you can monitor your LAN, the availability of network components and websites, and measure data streams and bandwidth usage. PRTG reduces costs by helping to avoid failures, which it achieves by optimizing websites, saving time and checking SLAs (Service Level Agreements).

Website monitoring with PRTG can be set up in a matter of minutes. Special sensors like the HTTP sensor, HTTP content sensor, HTTP advanced sensor, HTTP transaction sensor and many others enable simple HTTP queries as well as simulating website visitors with various actions, such as user logins or filling out forms.

High loads due to a high number of simultaneous visitors can slow down a web server significantly. Load tests can determine the performance reserves of a website. Paessler’s Webserver Stress Tool can be used to execute various web server performance tests.

Established Website Monitoring Using the HTTP Transaction Sensor

PRTG’s HTTP sensors enable you to quickly and easily set up monitoring for your website to ensure that you are always informed of the current status of your web presence. Just create a new sensor and enter the URL of the website that should be monitored. You can find further details on how to configure HTTP sensors in our online manual.

PRTG Network Monitor’s HTTP Transaction sensor can monitor several URLs on a web server. This is especially beneficial if you are interested in monitoring the functionality of your entire website, for example the shopping cart and confirmation pages as well as the shop landing page.

Another important sensor for website monitoring is the HTTP Content sensor. This sensor queries an HTTP URL and returns the result as a value in brackets—"[Value]". This sensor is usually used to monitor values on a website for their validity. If running a script or CGI on a web server that simply publishes free disk storage or current processor capacity, for example, these values and many others can be monitored with this sensor.

DNS and FTP Sensors for Comprehensive Monitoring

Statistics (availability, bandwidth/traffic, CPU usage, alarms) provide the fastest overview of the current status of an entire network.

PRTG’s DNS and FTP sensors are very useful in the context of website monitoring.

The DNS sensor sends a query to a domain name or IP address which is used to check whether the webserver is available externally or a DNS server is available in a local network. The FTP sensor checks whether data traffic via FTP is executed successfully and whether the FTP server is available.

You can find more tips for setting up and configuring web server monitoring via HTTP transaction sensor in our Knowledge Base.

IIS Monitoring

PRTG also allows you to monitor the number of current IIS users and sessions. For more information, please go to our blog article on how to monitor IIS.

  3. Add your first HTTP Sensor
  4. Refine the monitored aspects

This additional step helps you to make your website monitoring even more productive: Create notifications.

Setting Up Your Website Monitoring in 5 Easy Steps

Whether you are in the process of launching a new startup, or want to ensure access to your well-established website,
just follow these 5 easy steps in order to setup your website monitoring:

1. Download and installation

Download PRTG Network Monitor Freeware on and install it in just about two minutes by following the installation wizard. After successful installation, you can log in to the PRTG web interface by selecting the Default Login button. For a new installation, PRTG will open the Configuration Guru automatically after every login. You can either run through it completely or skip it. It will help you in configuring your installation by asking you 10 simple questions about your network. You can also adjust these settings later.

2. Add your web server to PRTG

Add a “Device” to PRTG that represents your web server. Each device in your PRTG installation represents a real hardware device (or a virtual one), you just have to provide its IP address or DNS name. To do so select Devices | Add Device from the PRTG main menu bar and choose a group for your web server (or create a new group) where you want to add it to. Enter a name for your web server and provide its IP address or DNS name.

3. Add your first HTTP sensor

Add your first HTTP sensor to the device that represents your web server. Just select Add Sensor from the context menu of the device in PRTG and follow the assistant. A good start is to create the standard HTTP Sensor. Using this sensor is the easiest way to monitor if your website is reachable. In the settings of this sensor, provide the address of the page (or page element) you want to monitor. Now you are able to see always at a glance if your website is available and if its loading time is accurate.

4. Refine the monitored aspects

To get an overview of all aspects of your web server, add more HTTP sensors for critical URLs. Using PRTG’s Smart URL Replacement functionality, you do not need to provide the domain part of the address but only the path of the subpages you want to monitor. Additionally, use other HTTP sensor types for different use cases. For example, you can check the content of the delivered web site or monitor the user experience of a whole process like purchasing in your web shop.

5. Review and analyze

Let PRTG collect performance data of your web server and web pages for a while. The incoming measurements are stored in PRTG’s high-performance database so you can easily review and analyze all received data. Comprehensible data graphs make it easy for you to get a good feeling about the status of your website.

Great! You have accomplished these few steps and got a full-scale insight about your website without any costs or a complicated and time-consuming configuration!

Create Notifications for More Productivity

As a user who already has spent some time on monitoring your web servers and web pages, you might want to enhance the monitoring workflow by creating notifications.

Of course, you do not want to look at PRTG’s web interface all the time so that you do not miss any error message. Rather create a notification that alerts you autonomously if your website shows unusual behavior, for example, via email, SMS text message or push notification.

By default, the HTTP sensor turns into an error status if there was an HTTP error or connection timeout within the last scanning interval. If you want to be warned on slow response times, you can also define warning and error limits for this value. This mechanism sets the sensor status accordingly and the defined notification in combination with a State Trigger makes you aware of possible issues automatically.

As long as PRTG does not contact you, you can be sure that your website runs perfectly and you can care about other parts of your business!

What’s next?

Besides having a full website monitor up and running in minutes, you also get a comprehensive monitoring solution with PRTG. You can utilize limits and the notification system of PRTG to be always up to date about the status of your network.

Additionally, you have access to a wide variety of other sensor types like Ping, SNMP Traffic, WMI based sensors, and many more. Discover the various sensor types of PRTG. Find more information about sensors here.

You quickly need a report about the health and other values of your network? No problem at all!

A monthly report is not enough for your colleagues? Don't despair, just create a nice visually sophisticated PRTG Map (also known as “dashboard”) and share the live status of your network with your team/customers.
