- CPU, memory, and storage contention insights
- VM sprawl and idle resource detection
- Faster root cause identification

## Connect VM, host, and storage performance with OpManager

Virtual environments are dynamic: VMs move, workloads shift, and resources get overcommitted leading to hidden issues like latency and contention. The challenge is that symptoms rarely reveal the root cause; a slow VM may appear as high CPU usage but stem from resource contention or storage bottlenecks. Most tools lack context, forcing teams to switch between layers and delaying resolution. [ManageEngine OpManager](https://www.manageengine.com/network-monitoring/?vir-mon) connects VM, host, and storage metrics in a single view, helping teams quickly identify root causes and resolve issues faster without manual correlation.

### Prevent VM slowdowns in VMware & Hyper-V by watching the host layer

![Hypervisor and Host Monitoring](https://www.manageengine.com/network-monitoring/images/virtualization-monitoring/prevent-vm-slowdowns.webp)

- **Identify CPU scheduling delays that traditional monitoring misses:** A VM may have CPU assigned, but still be waiting to run. OpManager helps you catch that kind of contention early through metrics like [CPU ready time](https://www.manageengine.com/network-monitoring/tech-topics/cpu-ready.html?vir-mon) across VMware and Hyper-V environments.
- **Track memory pressure beyond basic utilization:** See when hosts are reclaiming memory through ballooning, swapping, or compression, so hidden pressure is easier to spot.
- **Balance workloads using real utilization insights:** Find overloaded hosts early and redistribute workloads before performance issues spread across multiple VMs in your VMware or Hyper-V setup.

### Gain visibility into every VM across VMware, Microsoft Hyper-V & Nutanix

![VM Performance Analytics](https://www.manageengine.com/network-monitoring/images/virtualization-monitoring/vm-performance-analytics.webp)

- **Pinpoint noisy neighbors impacting shared resources:** Identify VMs that are consuming disproportionate CPU, memory, or I/O and creating contention for others on the same host.
- **View virtual disk and NIC details in context:** See the attached virtual resources that support each VM, so storage and network-related issues are easier to investigate across VMware, Hyper-V, and Nutanix environments.
- **Identify active processes driving CPU and memory usage:** Find out which processes inside the virtual server are consuming the most resources, helping you separate application-level issues from infrastructure problems.
- **Use virtual server reports to spot trends over time:** Review historical behavior and usage patterns to support troubleshooting, rightsizing, and [capacity planning](https://www.manageengine.com/network-monitoring/capacity-planning-reports.html?vir-mon) across your virtual infrastructure.

### See when storage is the real performance problem

![Datastore and Storage Visibility](https://www.manageengine.com/network-monitoring/images/virtualization-monitoring/datastore-and-storage-visibility.webp)

- **Detect latency spikes that cascade across VMs:** A single datastore issue can impact dozens of VMs: identify and address it before it spreads.
- **Correlate IOPS and throughput with VM performance:** Understand whether storage is the bottleneck behind application slowdowns, not just a secondary symptom.
- **Turn datastore growth trends into proactive capacity decisions with Zia:** See how storage usage is evolving, understand where risk is building, and [act on recommendations before capacity becomes a performance issue](https://www.manageengine.com/network-monitoring/zia-dashboard.html?vir-mon).

### Control VM sprawl with proactive detection and idle resource management

![VM Sprawl Detection](https://www.manageengine.com/network-monitoring/images/virtualization-monitoring/vm-sprawl-detection.webp)

- **Visualize sprawl from a dedicated dashboard:** Get a clear view of idle, oversized, and underutilized VMs with [VM sprawl management software](https://www.manageengine.com/network-monitoring/tech-topics/how-to-prevent-vm-sprawl.html?vir-mon) so cleanup opportunities are easy to identify.
- **Track VM growth across clusters and environments:** See where your environment is expanding and how that growth is affecting resource consumption.
- **Reclaim unused resources with more confidence:** Make cleanup and rightsizing decisions based on actual usage, not assumptions or guesswork.

### Automate repetitive fixes and reduce manual effort

![Automation and Workflow Actions](https://www.manageengine.com/network-monitoring/images/virtualization-monitoring/automation-and-workflow-actions.webp)

- **Automate responses to recurring infrastructure issues:** [Trigger predefined actions like VM restarts or resource adjustments](https://www.manageengine.com/network-monitoring/it-workflow-automation.html?vir-mon) to resolve common problems without manual intervention.
- **Standardize incident handling across environments:** Use repeatable workflows to make responses more consistent across teams and platforms.
- **Reduce operational overhead across teams:** Spend less time on repetitive troubleshooting and more time improving performance and capacity.

### Connect virtualization, network, and application performance

![Unified Monitoring Approach](https://www.manageengine.com/network-monitoring/images/virtualization-monitoring/unified-monitoring-approach.webp)

- **Track Rx and Tx traffic across virtual interfaces:** Monitor traffic and utilization across virtual NICs to see when network activity is contributing to VM performance issues.
- **Visualize relationships with organization maps:** [Understand how virtual resources are structured and connected](https://www.manageengine.com/network-monitoring/organization-map.html?vir-mon), which makes navigation and troubleshooting easier in larger environments.
- **Correlate virtualization with network and application performance:** Give infrastructure, network, and operations teams a shared view of what is happening, so issues are easier to resolve together.

## See, understand, and resolve VM issues faster with OpManager

### 1. Discover new VMs and hosts without manual effort

Your environment is dynamic, your monitoring should be too.

- **Auto-discover VMs, hosts, and clusters as they come online:** As new VMs are provisioned or workloads shift across clusters, OpManager automatically brings them under monitoring—no agents, no manual mapping.
- **Track VM lifecycle changes without losing visibility:** vMotion, live migration, provisioning, decommissioning—every change is reflected in real time, so your monitoring never falls out of sync.
