Why virtual environment monitoring is a must


The great advantage of virtualization is that it allows you to dynamically allocate resources such as memory, hard disk space, and processing power to individual applications and programs. A monitoring tool is vital for ensuring this allocation is done in an efficient and optimal manner. With a monitoring tool, you’ll immediately see if resources are being used or distributed properly or if it makes more sense to upgrade the network.

Since hardware is shared by several applications and operating systems at the same time, one malfunction can have a drastic impact on your entire business. Monitoring is therefore of the utmost importance.














VMware vRealize Operations monitoring software at a glance

VMware vRealize Operations (formerly vSphere Operations Manager) compiles server load data and facilitates capacity planning. It provides for detailed information on the performance of your vSphere environment and helps you to effectively allocate resources to virtual machines and optimize loads.

Unlike PRTG, VMware vRealize Operations cannot monitor components such as server hardware and your network. PRTG is therefore the perfect complement to VMware monitoring software. Another advantage: PRTG licenses are not just limited to VMware monitoring. They enable you to monitor all the other elements and services in your network, such as the bandwidth usage of your applications, the availability and performance of your websites, and the available disk space of your network drives.


PRTG offers comprehensive monitoring on many different levels

Although detailed and comprehensive, vRealize Operations monitoring is limited to the “internal view” of the virtual environment. With PRTG Network Monitor, you can monitor your VMware environment on many different levels – from hardware to the services on your virtual machines.

  • Monitoring physical servers
  • Monitoring server hardware with the ESXi hypervisor
  • Virtual machines as seen by the hypervisor (VM from outside)
  • Guest operating system (VM from inside)



1. Monitoring physical servers

Every VMware virtual environment runs on a physical server. PRTG provides for a convenient overview of hardware parameters such as temperature, power supply, and the status of fans. PRTG Network Monitor comes with built-in sensors for HPE ProLiant, Dell, Fujitsu, and IBM X-Series servers.


2. Monitoring server hardware with the ESXi hypervisor

The next level is the hardware of the ESXi host. PRTG provides additional information on the hardware behind your virtual environment.
The VMware Host Hardware Status (SOAP) Sensor monitors the hardware status of a VMware host server. It displays the total number of elements in the normal, warning, and alert statuses reported by the VSphere Client. This overview of the status of your host lets you know if everything is working properly.

The VMware Host Hardware (WBEM) Sensor is perfect for obtaining more detailed information on the hardware behind your virtual components. By using the management IP address of your ESXi server as a parent device, you’ll receive data on the hardware’s temperature, power supply, and fans (RPM).


3. Virtual machines as seen by the hypervisor (VM from outside)

Along with the hardware, PRTG can of course be used to monitor the virtual machines themselves. When monitoring from outside, you’ll get all the data on the virtual machines that is collected by your hypervisor. The VMware Virtual Machine (SOAP) sensor displays data on CPU usage, memory, datastores, and the network load.


4. Guest operating system (VM from inside)

You can use standard PRTG Windows and Linux sensors to monitor the guest operating system installed on your virtual machine. You’ll get data on active processes and services, datastore loads, and more.

The VMware Datastore (SOAP) sensor keeps an eye on the availability and utilization of your data memory. This sensor is especially important if you’ve limited the capacity of each virtual machine or the sum of all VM datastores surpasses the total data storage capacity. You can choose to be automatically notified in the event that one of your predefined capacity threshold values is exceeded. This will help you prevent data corruption and the freezing of your system.
