3 common questions on virtual machine monitoring 

What is a virtual machine

Sometimes called a hypervisor, a virtual machine monitor is a virtualization layer installed on a host system. This system usually corresponds to a hardware environment. The virtualization layer allows IT managers to control virtual machines running on the hypervisor as guest systems. Hypervisors make it possible to run multiple virtual machines on one main system and help manage the allocation of resources.


What is virtual machine monitoring?

Virtual machine monitoring involves the continuous monitoring of virtual machines, hypervisors, and the servers on which they run. Among other things, it allows for the monitoring of availability and performance. If a server goes down, so will the virtual machines that are running on it. With virtual machine monitoring, you can also monitor the specific parameters of virtual machines.


What is virtual machine monitoring software?

Virtual machine monitoring software is used to monitor availability and performance from one central location. In the event of errors or disruptions, system administrators are immediately notified by an alarm. Virtual machine monitoring software also comes with dashboards that provide managers with an overview of their entire virtualization environment or virtual infrastructure. Companies often use a variety of virtualization platforms, and the monitoring of virtual machines can put a huge strain on the network. It is therefore a good idea to monitor specific aspects of VMs directly.

Virtual environments are just one part
of the whole: Five
advantages of PRTG

Stand-alone monitoring solution

There’s a lot of virtualization software out there, and each tool has its pros and cons. What’s more, large IT systems often contain hardware from many different manufacturers. This makes monitoring extremely difficult. PRTG is a stand-alone monitoring solution that monitors your entire system.

Customizable alarm 

In the event of dips in performance or downtime, PRTG notifies you at once. Our software lets you set your own notification threshold values, as well as the means by which you are alerted. As a result, you’re sure to have plenty of time to fix the problem.

Capacity planning

Round-the-clock monitoring lets you optimize your IT resources. You’ll immediately see if capacity is reaching its limit. PRTG generates easy-to-read charts that help you convince higher-ups of the need for additional resources.   

Entire IT infrastructure

Our network monitoring software monitors your entire IT infrastructure, including both physical and virtual devices. It also monitors bandwidth, traffic, and various applications. PRTG is an all-in-one tool.    

One main dashboard

All monitoring data is consolidated on one main dashboard on your desktop, smartphone, or tablet. No matter where you are, a quick glance is all it takes to see if everything is OK.
