# VM Summary

VM Summary is everything about one virtual machine on one page: what it was allocated, what it actually uses, how that has moved over time, what it costs, and how its disks are configured. It is the screen you open before making a decision about a specific workload, and the screen you open afterwards to check the decision held.

## What this screen shows

- **Capacity score, allocated resources, and current utilization.** The headline position for the VM.
- **Trend charts.** CPU, memory, and disk over time.
- **Cost breakdown.** Split across CPU, memory, and disk.
- **Disk configuration table.** Every disk with its size and usage.

## When to use it

- **Validating a right-sizing candidate.** The portfolio screen nominates, this screen confirms.
- **Troubleshooting.** Correlating utilization against storage usage often explains behaviour that neither metric explains alone.
- **Quantifying cost drivers.** The three-way split tells you whether a VM is expensive because of memory, cores, or disk, and therefore what to change.

## The question the trends answer

Low utilization on a single snapshot is not evidence. The trend charts exist to establish whether it is persistent or seasonal, and that distinction is the whole right-sizing decision. A month-end reporting VM, a quarterly batch job, and a genuinely oversized application server all look identical on a Tuesday.

The disk table serves the same purpose on the storage side. Find the largest disks and check their usage percentage. One heavily over-allocated disk on an otherwise reasonable VM is a common and easily corrected pattern.

> **Tip:** After a right-sizing change is applied, come back here once the next collection has run. Allocation should have dropped and utilization percentages should have risen into a healthy range without the VM becoming constrained.
