VMware Monitor
Network Monitor for VMware Environments
Server virtualization is the latest major technology trend in the data center. Where server virtualization has been applied rigorously, it has both enormous and positive impacts on corporate power and cooling expenses as well as data center capacity.
But when a virtualized server crashes, or its network connection slows or breaks, it impacts all the applications on that server. A VMWare monitor provides vital information for planning, testing and monitoring virtualized environments.

PRTG Network Monitor is a VMware monitor that helps you identify if insufficient resources have been allocated to a specific virtual machine. The software also indicates if the virtual infrastructure is adversely affecting the network in terms of traffic and degradation, and will monitor the virtualized environments in real time.
Why Monitoring is Important Before And After Setting up Virtual Environments
- Virtualizing systems without knowing their usual CPU/Memory load, disk usage and network usage is risky. With a VMware monitor you can analyze your system prior to virtualization in order to know how much load it will put on your VMware Host servers. Systems with high load may not be suitable for virtualization at all.
- Once the servers are virtualized, you need to ensure that there are not too many VMs running on a single host, potentially causing overloads across the virtualized systems. A VMware monitor helps keep the server's utilization at 75%.
- You might also wish to avoid running too few VMs on a host, as this might involve wasted resources on unnecessary host servers.
- The mid/long term network monitoring results before and after virtualization provided by PRTG Network Monitor help to ensure that quality of service doesn't suffer.
- The performance of all virtual systems on a host usually suffers from one virtual system running amok, or running into a performance/load peak. A good VMware monitor discovers such events quickly.
PRTG - Certfied VMware Monitor
As a VMware partner, Paessler AG not only uses VMware solutions in its own environment, but also integrates device templates for VMware monitoring into PRTG Network Monitor:
- VMware ESX Host Server: monitors a VMware ESX Host Server
- VMware Virtual Machine: monitors a single Virtual Machine on the host server
While the ESX Host Server sensor only works directly with an VMware ESX 3.x server as its parent device, you can use the virtual machine sensor in two ways:
- Use it to directly communicate with a VMware ESX 3.x Host Server to monitor virtual machines running on this server.
- Use it to communicate with a VMware Virtual Center installation to monitor all virtual machines managed by this virtual center.
This is the only option that supports virtual machines running on VMware Server 2.x and virtual machines under control of VMware's VMotion feature.
Setup Your VMware Monitor
Setting up a VMware monitor with PRTG Network Monitor is as easy as 1-2-3. After installing PRTG you can quickly create the ESX or Virtual Center Server as a new device as follows:
- Choose "add sensor"
- Add a device based on the respective host/ virtual server
- Select VMware Servers
- Select a sensor type
- "VMware Virtual Machine" to add sensors for the virtual machines
- "VMware ESX Host Server" to ad a sensor to monitor values of the ESX server itself
- The VMware ESX Host Server sensor only works if the device is an ESX Server! This sensor does not work on Virtual Center Servers.
Free, Trial And Commercial Editions
You can test PRTG for free with the 30-Day-Trial-Edition. The Freeware Edition is completely free for personal and commercial use and may be downloaded at no cost.
The Commercial Editions are required if you want to monitor more than ten sensors. Licenses for PRTG start at $380 / €250.
