Virtualization Monitoring

Key Features for ESX/i:

• Alarms and Flags Monitoring
  Avoid potential issues with real-time alerts and flag status updates, allowing preemptive action.
• State and Performance Tracking
  Continuously monitor the health and performance of your ESX/i hosts to optimize your virtual infrastructure.
• Enhanced Status Views
  NetCrunch delivers specialized views for ESXi machines, featuring:
  • Hardware Status Gain an in-depth understanding of your hardware’s health.
  • Virtual Machines Overview Effortlessly oversee all your VMs in a unified view.
  • Datastore Monitoring Ensure your data storage systems perform reliably.

NetCrunch's intuitive platform enables the automatic addition of VMs to the monitoring list, simplifying your virtual management processes.

In addition to these features, NetCrunch monitors vital aspects such as CPU Usage, Memory Usage, Disk IO, Network Utilization, the number of running and total VMs, Used CPU Hz, and Used Memory Bytes.

The overview grid for ESXi provides detailed information on Overall Status, Power State, Config State, Hardware Health, Triggered Alarms, Hardware, Flags, CPU and Memory Usage, Number of Virtual Machines, Data Center, Cluster, and Connection Mode.

While NetCrunch can connect directly to ESXi in scenarios where vCenter is not available, note that direct mode monitoring may have limitations.
