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.
