# Virtual Environment

Virtual Environment is the top-of-funnel view. Each environment or vCenter is summarized, and every cluster inside it renders as a card carrying its utilization and scale. It is built for comparison rather than analysis: you look at it to decide where to look next.

## What this screen shows

- **Environment summary.** Total memory, memory allocated, CPU and disk utilization, and cluster count for the environment as a whole.
- **Cluster cards.** One per cluster, showing % CPU, % Memory, % Disk, host count, VM count, and the underlying raw resource values.

Percentages and raw values appear together deliberately. A cluster at 85% memory with a small footprint is a different decision from a cluster at 85% memory holding several terabytes, and a percentage alone hides that.

## When to use it

- **Comparing environments or vCenters at a glance.** Particularly useful where different sites or business units run their own vCenter.
- **Spotting outliers.** Clusters running high on memory, CPU, or disk stand out against their neighbours.
- **Deciding where new workload goes.** The cards give you the placement answer without opening five screens.

## How to work it

Scan for high memory utilization first. Memory is the constraint that binds first in most virtual estates, so a cluster running hot on memory while CPU looks comfortable is the normal failure pattern rather than an anomaly. Use the cards to pick a drill-down target, then move to the per-cluster screens for the detail.

> **Tip:** This screen shows utilization, not runway. A cluster sitting at 60% memory that has climbed twenty points in a quarter is a bigger problem than one that has sat at 80% for two years. Check trends before you trust a snapshot.
