Performance Metrics for VMware Cluster Monitors

Monitor VMware clusters to understand their Effective Storage capacity, Distributed Resource Scheduler (DRS) Configuration, DRS Faults, DRS Migrations, Total Storage Consumed, VM Operations, Memory Usage, and more in the user's environment. The VMware Cluster monitor is automatically added while adding vCenter monitor.

By monitoring a VMware cluster, you can:

Understand the CPU and memory usage across the entire cluster.
Add a threshold and availability profile to declare a specific resource as critical or down.
Analyze critical performance issues using reports.
With a DRS Cluster, you can collect DRS Configuration, DRS Faults, DRS Migrations, and DRS Recommendation.

Summary

Attribute	Description
Effective Memory	Displays the effective memory resources (MB) available to run VMs.This is the aggregated effective resource level in all VMware ESX/ESXi hosts to run the VMs.
Effective CPU	Displays the effective CPU resources (MHz) available to run VMs. This is the aggregated effective resource level in all VMware ESX/ESXi hosts to run the VMs.
Total Storage Consumed	Displays the aggregated storage space available under cluster.
Total Datastore Capacity vs Usage	Displays the comparison graph of total datastore capacity (MB) and the actual amount used (MB).
Cluster Details	Displays various information such as CPU Cores, CPU Threads, CPU Capacity (MHz), and Memory Capacity (GB).
DPM Configuration	Displays the configuration details of Distributed Power Management (DPM) feature, if enabled in the cluster.

DRS Configuration

Attribute	Description
