PRTG vs. VMware vRealize Operations: All-in-one network monitoring, virtualized or not

PRTG is the perfect complement to VMware monitoring software, providing the comprehensive scope of monitoring that VMware is lacking.

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

However, PRTG does something VMware vRealize Operations cannot do: PRTG also monitors components such as server hardware along with your entire network.

In fact, PRTG can 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.






Fast setup and intuitive usability

Network monitoring should be quick and easy. Cumbersome and complicated software creates unnecessary work for the administrator. PRTG makes monitoring as user-friendly as possible – no matter if you choose an on-prem installation or our cloud-based product.

Quick installation with automatic network discovery and smart setup for instant monitoring

Different user interfaces for web, desktop, and mobile apps for monitoring on the go

Custom dashboard creation via drag & drop with easy-to-read visualized overviews

Network of qualified implementation partners to support you with a smooth migration to PRTG

What VMware environment monitoring looks like in PRTG

Diagnose network issues by continuously monitoring the health, availability, and performance of your virtualized infrastructure, as well as your entire network. Show hardware, hypervisor, virtual server, virtual application stats, and more in real time and visualize data in graphic maps & dashboards to identify problems more easily. Gain the visibility you need to troubleshoot all kinds of issues in your virtual network.

Comprehensive virtual network monitoring on many different levels

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

Check physical servers from various manufacturers

Every VMware virtual environment runs on a physical server. PRTG comes with many built-in sensors for the most important manufacturers such as HPE, Dell, Fujitsu, or IBM. Hardware parameters that PRTG monitors include CPU temperature, power supply, and the fan status.

Keep an eye on the server hardware of the ESXi host

PRTG provides additional information on the hardware behind your virtual environment with the ESXi hypervisor.

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 status reported by the vSphere Client.

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).

Monitor virtual machines as seen by the hypervisor

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 ESXi hypervisor.

The VMware Virtual Machine (SOAP) sensor displays data on CPU usage, memory, datastores, and the network load.

Monitor the guest operating system on the VMs

You can use standard WMI and SSH 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 usage 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.

"One of PRTG's greatest strengths is certainly its very good user-friendliness. Beyond that, the ability of the software to group all sources of information in a single point is useful. This is how we connect physical equipment, applications, or our VMware Cloud Director consoles to PRTG. The ease of use is incomparable compared to the free solution that we previously used."

PRTG vs. VMware vROps: FAQ


Should I choose PRTG or VMware vRealize Operations?

Choosing between Paessler PRTG and VMware vROps depends on several factors, such as your specific network monitoring needs, budget, and technical resources available in your organization.

PRTG is ideal:

  • If you prefer an all-in-one, easy-to-use solution with minimal setup time.
  • If you need sophisticated, customizable visualizations like dashboards and network maps.
  • If you want to monitor an unlimited number of remote locations and networks at no extra cost.
  • If you prefer high scalability and a software tailored to large, complex environments.
  • If you want to get real-time alerting, custom notifications, and automated reporting.
  • If you want to have the choice between an on-premises or cloud-based solution.
  • If you want a straightforward licensing model at a comparatively low price.

VMware vROps might be your choice:

  • If your environment is heavily virtualized and relies on VMware products
  • If you need advanced analytics, automation, and machine learning for predictive insights and anomaly detection
  • If your organization has the budget for a generally more expensive solution

Why is virtualization important?

Virtualization using VMware products, for example, is a crucial part of many IT environments and an effective way to reduce expenses while boosting efficiency and flexibility of your business. It allows you to distribute applications and databases over different servers, networks, and locations. To avoid downtimes and ensure a good overall performance, you should monitor your VMware servers and all of your virtual machines.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
