Keep a constant eye on the following
three website parameters with PRTG

 Detailed load times

Worldwide availability

Use PRTG to monitor the availability of your website, around the clock, 365 days per year. To do so, take advantage of our HTTP Sensor and the HTTP Advanced Sensor. International companies can monitor availability from a variety of locations or across several continents. These companies will want to use our Cloud HTTP v2 Sensor and Cloud Ping v2 Sensor.


Detailed load times

Detailed load times

How much time does it take for your website to load? How do load times change over an extended period of time? Monitor these parameters with our HTTP Full Web Page Sensor. This sensor will also allow you to identify the individual elements which are responsible for slow load times – the basis for system optimization.


Processes and features

Processes and features

Are all website processes running smoothly? What about the online store? Everything should be running properly, from the homepage and shopping cart, all the way to the confirmation page. When it comes to website processes, the HTTP Transaction Sensor lets you monitor a whole series of URLs. PRTG can therefore also be used as a URL monitoring tool.

Setting up PRTG
in 5 easy steps


iWhat is a sensor?

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.

Configure PRTG 

Configure PRTG

Configure PRTG Network Monitor. Follow the instructions in the configuration wizard. No more than two minutes are required for the configuration. Once you have successfully configured the software, you can now access the PRTG web interface by way of the standard registration page. For new configurations, PRTG automatically opens the Configuration Guru after each login. The Guru will help you set up PRTG by asking you a few questions about your network. You can also skip the Guru and set your preferences manually at a later time.

Add your web server to PRTG 

Add your web server to PRTG

Add a “device” to PRTG that represents your web server. Each device in your PRTG configuration represents a piece of physical hardware or a virtual element, which you can associate with an IP address or a DNS name. Choose “Devices | Add Device” from the PRTG main menu, then add your web server to an existing group, or first create a new group and add the web server to that one. You can now name your web server and enter its IP address or the DNS name.

Add the HTTP Sensor to PRTG

Add the HTTP Sensor to PRTG

Add the device that represents your web server to your first HTTP sensor. Choose “Add a Sensor” from your device’s context menu and follow the instructions in the wizard. To begin with, you can use the HTTP sensor which has been most effective at checking the availability of your website. Next, in the settings of this sensor, specify the address of the site (or the site element) you wish to monitor. You can now see, at a glance, if your website is available and if its load time lies within acceptable limits.

Expand your web monitoring 

Expand your web monitoring

In order to obtain an overview of your entire web server, simply add HTTP sensors for each critical URL. Thanks to the ability of PRTG to intelligently replace URLs, you only need the path of the subpage you wish to monitor, and are not required to enter the entire domain part of the address. Additional HTTP sensors provide for more comprehensive website monitoring. You can use them, for example, to check the content of a delivered page or monitor all the processes used by your online store.

Evaluate and analyze data 

Evaluate and analyze data

Let PRTG collect the performance data of your web server and websites over a certain period of time. The incoming measurements will be saved in the high-performance database of PRTG. This makes the evaluation and analysis of data both simple and uncomplicated. Furthermore, thanks to the graphical representation of your data, you will get a comprehensive overview of your website status.

Practical tip: “Hey Jochen, what would you tell administrators looking to monitor
their websites with PRTG?"

“I am especially fond of the HTTP Content Sensor, for this sensor can monitor all kinds of website information. It lets me test the login of a website, determine the number of website visitors, and on release notes pages, see if a new software version is available.”

Jochen Greger, Senior Systems Engineer at Paessler AG


4 tips for
improving the
load times of
your website

All websites get bulkier over time. It is often a slow process. Meanwhile, users become more and more impatient. It may be high time your website gets into shape. Check out our free Website Performance Ebook for some practical tips. Here are a few examples:

Change your database server

Change your database server

Many companies use MySQL. But is this server the best fit for your specific needs? What are the other databases that are out there? When researching database servers, be sure to also compare their load times.

Reduce CPU load

Reduce CPU load

In some instances, your CPU is brought to its knees. This can occur when you have an online store and have just launched a marketing campaign. Be prepared by booking additional cloud space in advance.

Reduce CPU load

Set up caching

With caching, you will ensure the files and elements of your website do not need to be reloaded each and every time a page is visited. You will therefore substantially reduce load times. With Typo3, caching is often disabled during development. Check with your developer to see if this is the case for your site.

Reduce the size of images

Reduce the size of images

Each image should be compressed by default. Save all images in a web-friendly format. You can also delete unnecessary metadata to make your website significantly more compact.
