Cost Optimization

Performance Metrics

StratoLens collects performance metrics to identify idle resources and provide VM sizing recommendations. Usage data that answers sizing questions: which VMs are oversized, and which resources sit idle.

StratoLens is a self-hosted Azure visibility platform. It runs in your own tenant; your infrastructure data never leaves it.

The Problem

Cost optimization features need usage data to be accurate:

Sizing Without Data: Right-sizing VMs without performance history means guessing
Idle Detection: Identifying unused resources requires knowing actual utilization
Missing Context: Recommendations without usage data lack confidence

The Solution

StratoLens collects performance metrics to power its optimization features:

VM Sizing: CPU, memory, and disk metrics drive right-sizing recommendations
Idle Detection: Usage patterns identify resources with no recent activity
Historical Context: Utilization trends over time inform confident decisions

From the product

Inside Performance Metrics

StratoLens performance metrics showing CPU and memory utilization charts for an oversized Azure VM running far below capacity — Utilization charts from the Contoso Financial demo environment for a very large VM whose CPU barely registers, the evidence behind its right-sizing recommendation. Shown with demo-environment data.

A batch fleet whose utilization sawtooths every night, working hard for a few hours and sitting idle the rest of the day.

The memory side of the same story: a very large VM using roughly a fifth of its 512 GB, confirming the smaller SKU fits with room to spare.

Self-hosted

Runs in your tenant. Reads everything, changes nothing.

StratoLens deploys from the Azure Marketplace into your own tenant and scans your subscriptions over read-only Azure APIs. The data behind Performance Metrics is collected and stored inside your tenant; there is no StratoLens cloud holding a copy.

Read-only scans via Azure management APIs
Every scan at rest in your tenant, never a vendor cloud
Deployed from the Azure Marketplace in under 15 minutes
