Virtualization Layer Observability
Virtualization Layer
Monitoring & Observability
The Virtualization Layer is the consolidation hub of the entire IT infrastructure, enabling efficient sharing of physical resources. Any issue at this layer may simultaneously impact dozens of virtual machines. With an effective Virtualization Layer Monitoring & Observability solution, you can detect performance degradation, capacity saturation or resource contention in real-time, and preserve service continuity through proactive scaling and automated load balancing.
Virtualization Layer Monitoring & Observability
Core Metrics and
Monitoring Objectives
Hypervisor
(ESXi, Hyper-V, KVM, etc.)
What It Shows:
High consumption of hardware resources, host failures or increases in latency.
Objective:
Detect performance bottlenecks and optimise system response time.
Virtual
Machines (VMs)
What It Shows:
OS-level CPU, RAM, disk I/O, network throughput and uptime figures.
Objective:
Ensure consistent VM performance and identify machines experiencing bottlenecks.
Datastore / Storage
Layer Integration
What It Shows:
Monitoring of LUNs, volumes, datastore latency and capacity linked to the virtualization environment.
Objective:
Detect I/O latency spikes, storage capacity exhaustion and throughput drop-offs early.
Cluster & vMotion
Activity
What It Shows:
Tracking DRS (Distributed Resource Scheduler), HA (High Availability) events, failover processes and migration movements.
Objective:
Ensure seamless VM redistribution upon host failures.
Snapshot
Management
What It Shows:
Monitoring snapshot creation frequency, retention and deletion times, sizes and lifecycle status.
Objective:
Reduce performance, storage and management risks by proactively managing snapshot lifecycles.
vSwitch / Virtual Network
Interface (vNIC) Health
What It Shows:
Constant monitoring of port-group connections, uplink statuses, throughput values, packet loss and latency.
Objective:
Identify latency or packet loss issues between VMs or between VMs and external networks.
Resource Pool
& Capacity Planning
What It Shows:
Continuous tracking of CPU, memory, disk and network allocation, limits and sharing ratios.
Objective:
Ensure physical resources are distributed fairly and effectively within the virtual environment.
Guest Tools
& Integration Status
What It Shows:
Status, update levels and synchronization errors of VMware Tools / Integration Services.
Objective:
Guarantee that in-VM metrics are collected accurately and up-to-date.
Licensing & API
Availability
What It Shows:
Hypervisor license status, API accessibility and continuity of monitoring-tool connectivity.
Objective:
Maintain the monitoring and management tool’s ability to collect data continuously.
Virtualization Monitoring
Core Questions
These Metrics Answer
Virtualization Layer Monitoring & Observability solutions provide end-to-end visibility across hypervisors, virtual machines, datastores and virtual network components. This allows IT teams to track critical metrics in real time (such as resource usage, performance trends, vMotion movements and snapshot growth) to proactively identify bottlenecks and capacity issues.
- Are there performance degradations during vMotion or HA events?
- Are datastore latency times affecting application response times?
- Are snapshots growing and unnecessarily consuming storage space?
- Are resources distributed evenly across hosts?
- Are VMs experiencing latency or freezing due to over-commitment?
