What our customers say

“It makes for a great one-stop shop for monitoring key VMware metrics! It comes pre-packaged with ready-to-use dashboards that are color coded with thresholds providing immediate feedback on performance, KPIs, health, and areas of concern. I’m very pleased with the application and the support team behind it. Highly recommended!”

“We use Opvizor for many many years successfully to troubleshoot performance issues, optimize resource usage and develop deployment guidance! I simply can't do my job anymore (that includes managing 3000+ VMs) without Opvizor.”

“The tremendous flexibility and the possibility to create your own dashboards with metrics and logs you want to keep one eye on it all the time across different infrastructure products from different vendors. I also like the amazing support from the Opvizor team!”

“With Opvizor we have a one-stop visualization to monitor our resources across our VMware infrastructure and Microsoft Azure cloud deployments. This makes it easy for us to pinpoint performance issues and their root causes independently of the platform. This is something difficult to achieve with the monitoring tools provided by either VMware or Azure.”

Performance monitoring, forecasting, reporting, event tracking

Optimize VMware performance and quickly resolve issues in your virtual machine environment

Powerful Dashboards

Monitor vital metrics of your most important virtual machines, check the network utilization of your ESXi host and much more from a single pane of glass.

Virtual Infrastructure Health

Always stay on top of your virtual infrastructure and feel the pulse of your environment.

Find Performance Bottlenecks

Finding bottlenecks is typically a pain, as you either don’t have the big picture, not the historic data required or you just don’t know the thresholds.

Threshold Monitoring

We guide you with easy to understand dashboards, embedded help and predefined thresholds.

Capacity Planning

Track the host and VM resource consumption over time and forecast resources needed in the future. Check how many new VMs can reside on the existing hardware.

Change Management

Track all kind of changes that happen in the lifetime of a virtual machine. Adding memory, setting a CPU limitation or changing the network port group should not happen unnoticed.

Data Correlation

Correlate the performance data in a chart with events that are happening on the virtual machine or the ESXi that provides the computing stack.

Beyond The Hypervisor

Thanks to our OS agents, integrations with physical network components and storage systems you can check the full stack and compare performance data yourself.

Need clarification?

Can I run Opvizor on-premises?

Yes, Opvizor runs without any internet connectivity.

Opvizor is available as a virtual appliance that you can import into your VMware vSphere environment. Patches can be downloaded from our customer portal and installed without any internet access. 

Do I need to install any agents to collect VMware vSphere data?

Many integrations work without installing an agent:

  • VMware vSphere
  • NetApp
  • Microsoft SQL
  • Oracle
  • PostgreSQL
  • Dell PowerMax
  • Cisco UCS
  • Cisco Switches
  • Brocade Switches

Agents are required for Operating System data and some applications.

How to analyze log data?

Opvizor supports the Syslog protocol and you can simply configure the ESXi hosts, the vCSA appliance and many other systems to send data to the virtual appliance.

How well does it scale?

Opvizor has been developed with scalability and efficiency in mind. Most deployments consist of a single virtual appliance that can consume all metrics, logs and configuration data. When exceeding 100 ESXi hosts and 1500 VMs, we recommend a split into 2 virtual appliances.  In any case, you see all data within the dashboards.
