Today, it is hard to see an enterprise that is not running some form of a virtual environment.
These enterprises are building hybrid environments running virtual, cloud, and on-premises infrastructure to run their workloads.
And all of that without underutilized computing resources, additional data center space, or large energy bills.
But no technology is great without proper management and monitoring.
Keeping a sharp eye on the entire performance and health of the virtual environment, from the workloads deployed on VMs to the underlying hardware of the host, is crucial.
In the following article, we will take a closer look into Top Tools and Software for Monitoring VM Performance.
Monitoring the Performance on your VMs
A performance issue on a machine hosting multiple VMs will not only affect the physical server, but it will also impact all the VMs and their applications.
So monitoring performance and health in the virtual environment becomes crucial for any business.
What Can Affect Performance in a Virtual Environment?
- Under- or over-allocation of resources. Over-allocation of resources to a VM leads to an unbalanced use and under-utilization of resources.
- Network traffic or overloaded interfaces. VMs also share the network. High utilization of network bandwidth or too much traffic on a single NIC can impact the performance on all VMs.
- Incorrect sizing and storage configuration. Poor storage can lead to performance bottlenecks.
Tracking resource usage metrics over time can help determine the right allocation of resources to each VM, save storage, and avoid network outages.
There are a couple of these metrics that can be monitored to stay on top of performance, like hardware health, network connectivity, VMs resource utilization, and Idle VMs.
Aside from tracking metrics, there are also some best practices to help you improve VM performance.
Making sure that your host OS is at top performance can help all your VMs.
For example, ensuring that your host disk is clean, defragmented, and that it is not running high-resource consuming applications, can improve the performance of all VMs.
You can also optimize VMs, by running them on separate hard drive instances and by optimizing them for the specific task.
Here's Best VM Performance Monitoring Software & Tools:
All the following VM monitoring tools and software are capable of at least keeping an eye on resources like CPU and memory and network stats, which are critical for virtual environments. All tools can at least send alerts based on a predefined threshold. Other advanced tools can monitor the entire virtual environment, perform predictive analysis, create reports, and more.
1. SolarWinds VM Monitor – (100% Free)
SolarWinds VM Monitor is a free and simple monitoring tool for VMware and Microsoft Hyper-V hosts and associated VMs.

SolarWinds VM Monitor keeps track of three important performance metrics on your server, the CPU utilization, memory, and the number of VMs.
You can change the threshold values for warning or critical for such parameters.
The SolarWinds VM Monitor will display the server with all its VMs.
Each VM line shows its name, status (Warning, Critical, or Ok) in different colors; it will also show the OS, the CPU in %, Guest memory in %, and Network (Tx and Rx).
Free for monitoring a single VM host and its associated VMs.

With PRTG sensors, you can monitor VMs from inside and outside.
- From outside: PRTG can monitor performance counters for multiple VMs running in a host server. Monitoring VMs that are impacting the network can help improve the overall performance. When a particular VM reaches its capacity, PRTG will send you an alert. Out-of-the-box, you can monitor different VM platforms such as VMware, Hyper-V, and Citrix XenServer.
- From Inside: With PRTG, you can also monitor a single VM with sensors like WMI, SSH, SNMP, etc. You can keep track of the operating systems within a single VM, but PRTG advice not to overdo inside monitoring, because sensors like WMI can produce high loads and traffic.
Since PRTG is a comprehensive monitoring tool, you can also keep track of the performance on the network, the host, and even VMs deployed in the cloud.
With PRTG, you can set your performance threshold values that activate the alarms.
You can see the alerts as warnings on the dashboard, or configure them to be sent to your email, SMS, or API.
Some of the PRTG sensors that can keep track of the VM performance:
- Virtual Servers Sensors
- Citrix XenServer Virtual Machine sensor
- VMware Virtual Machine (SOAP) sensor
- Citrix XenServer Virtual Machine sensor
- Hyper-V Virtual Machine sensor
- VMware Virtual Machine (SOAP) sensor
- And more.
The price for PRTG depends on the number of sensors. The basic license starts at $1,330 for PRTG500, which allows up to 500 monitoring sensors.
