Advantages of virtual servers


Virtual servers are among the most important elements of modern data centers. Virtual servers allow for significant improvements in the area of network performance. They can also optimize the distribution of resources and save money by reducing the need for expensive hardware. With non-virtual environments, sufficient memory and CPU capacity must be allocated to each application manually. With virtual servers, this allocation occurs dynamically. With virtual environments, all the servers and storage units in your network can be seen as one big, powerful computer.

Clustering improves the performance and availability of your servers



Upon virtualizing your servers, you have the possibility of merging them into clusters. If one server is down, then another computer in the cluster will automatically take over the virtual machines and applications. By consistently avoiding single points of failure, you’ll improve the availability of your servers.


 iVirtualization is the process of creating a virtual version of something like computer hardware. It involves using specialized software to create a virtual or software-created version of a computing resource rather than the actual version of the same resource.

Intelligent load distribution

Intelligent load distribution

Clusters are also used to intelligently distribute the network load to several different machines. This is especially important for environments with high performance requirements.


PRTG offers a precise overview
of your virtual environment

Easy-to-read display

Easy-to-read display

Reliable network monitoring software is important for ensuring the proper functioning of dynamic memory allocation. PRTG collects and analyzes all vital network data, then displays this data in easy-to-read charts and graphs. As a result, you get a crystal-clear overview of all your network’s activities. Along with important data regarding your virtual environment, you'll get information on bandwidth, traffic, and individual devices such as routers, switches, and printers.

Automatic notifications

Automatic notifications

If a virtual server in a cluster goes down, PRTG will send you an alert message at once. You can then take all the necessary steps to prevent more serious problems from arising.

This is how PRTG looks like


Why PRTG is the right tool for virtual server monitoring

Comprehensive overview

Comprehensive overview

Which virtual machines are running on which computers? How much memory is being used? What is the data transmission rate? PRTG will answer these questions and many more regarding your virtual servers. PRTG lets you create your own custom dashboards, which will allow you to see at a quick glance if your virtual servers are running as planned.

Detailed statistics

Detailed statistics

Along with a quick overview, PRTG offers a number of possibilities for taking a closer look. Extensive statistics are available for each measured value. You can, for example, view the average CPU load of the host or the amount of downtime that has occurred during the current year.

Upon request, PRTG will automatically send reports to your colleagues or superiors.

Straightforward capacity planning

Straightforward capacity planning

PRTG simplifies the capacity planning process. With your virtual server monitor, you can promptly determine if the network’s capacity needs to be increased. You’ll immediately see if your hardware is overloaded and can react quickly – before an overload leads to poor server performance or errors. The charts of PRTG are extremely easy to read, and therefore perfect for convincing higher-ups (who often lack technical know-how) that it’s a good time to upgrade the network. Conclusive data and statistics eliminate the need for long and nerve-racking discussions. 


Prompt error notifications

Your virtual servers are the backbone of your IT infrastructure. Malfunctions can not only paralyze business processes, but also lead to losses in sales. For each measurement point, PRTG lets you define a threshold value which, when reached, will immediately trigger an alarm. You can choose to be alerted by email, SMS, or push notification. Thanks to the PRTG alarm system, you’ll usually have time to intervene before errors occur and your coworkers start lining up outside your door. With the PRTG Server Monitoring Tool, you’ll keep downtime to a minimum.

Preconfigured sensors for monitoring virtual servers


 i What 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.

PRTG comes with preconfigured sensors to allow for fast and easy setup. With just a few clicks, you can add your virtual servers to PRTG and get started with your monitoring. Once your virtual environment is added to PRTG, you'll immediately begin to receive all the key data regarding your hosts, virtual machines, and applications. Neatly arranged dashboards and custom maps ensure you constantly get the information you need.
