Virtual machines

Read what each VM costs, how busy it is, and how to apply its rightsizing recommendation

The Virtual Machines page shows your compute instances across cloud providers. For each one, you see what it costs, how much of it is used, and what it would cost at the right size. VMs appear here once they run the CostGraph Agent.

Fleet

The top of the page summarizes the period you pick, month to date by default:

• VM spend, split into CPU, memory, and storage.
• Savings Available across all VMs, or Fully optimized when there is nothing to save.
• The five VMs that contribute most to spend.

Each row shows the instance, its location, type, pricing model, price, CPU, and memory. It also shows runtime over the last 30 days, month-to-date and projected cost, the recommendation, and status. The list shows active VMs by default. Filter by status, provider, region, availability zone, instance type, architecture, or operating system.

Apply a recommendation

Select a VM’s recommendation to open it. CostGraph compares the current and recommended instance types. It shows the estimated savings, or the added cost of an upsize, and the risk and effort of the change.

Choose how to apply it: Terraform, CLI, AI Agent, or Manual. CostGraph gives you the change for that method to run yourself. It doesn’t change the VM. See Recommendations for how CostGraph sizes a VM.

VM details

Select a VM to open it. The header shows its vCPUs, memory, and its cost this month against the projection. The tabs are Overview, Metrics, GPUs, and Containers.

Overview shows:

• System cost, split into CPU, memory, and storage, with the recommendation.
• The VM’s details: agent status and version, price, cost per hour, and running containers.
• Each disk’s type, size, IOPS, throughput, monthly cost, and a cheaper disk type where one exists.
• A heatmap of CPU, memory, and pressure over time, and what drives CPU load.

Metrics charts the VM over the last hour by default, or the last 6 hours, 24 hours, 7 days, or 30 days:

Section	Charts
CPU	Utilization, breakdown, contention, throttling, and system load
Memory	Utilization, composition, pressure, swap and reclaim, and working set
Disk	Filesystem usage, utilization, throughput, IO operations, and IO latency
Network	Traffic, throughput, and TCP retransmits
GPU	Utilization, memory utilization, and power draw

GPUs lists the accelerators attached to the VM. See GPUs.

Containers lists the containers running on the VM, with their status, CPU and memory usage, restarts, and uptime. Select one for its runtime, network, ports, mounts, labels, and metrics.

API

Everything on these pages is available in the CostGraph API under /api/v1/tenant/virtual-machines: the fleet and its summary, each VM, its metrics and containers. Graph AI and the MCP server read the same data.
