Performance Metrics

Read Azure Monitor utilization metrics (CPU, memory, disk, requests, storage) for any supported Azure resource without leaving StratoLens. The 95th percentile is highlighted on every chart as the key signal for rightsizing decisions.

What StratoLens collects, and why

StratoLens ingests a curated set of performance metrics, not the full Azure Monitor catalog. The set is chosen to feed Orphaned Resources detection and VM Sizing Recommendations, with this page as the place to inspect the underlying data directly.

What You'll Learn

Navigate the Subscriptions / Resource Groups / Resources hierarchy to find a specific resource
Read the detail panel: metric tabs, summary card, and chart
Interpret the 95th percentile and use it for rightsizing
Switch between time windows, daily / hourly granularity, and memory display modes
Check how much history StratoLens has on file via the Collection Window tab

Key Capabilities

Three-Column Resource Browser

Drill from Subscriptions to Resource Groups to Resources, left to right. Each column shows resource counts so you can see where to look before opening anything.

95th Percentile Highlight

Every chart and summary card surfaces the 95th percentile as a single number plus a dashed reference line on the chart. This is the value most teams use to decide whether a resource can be downsized.

Daily and Hourly Granularity

Switch between daily and hourly views to spot daytime spikes that a daily average smooths out. Hourly is offered when the resource type collects it.

Per-Resource Collection Window

A dedicated Collection Window tab shows how many days of daily data and hours of hourly data StratoLens has stored for the resource you're viewing.

Feature Integration

Performance Metrics is the data source behind several other StratoLens recommendations:

VM Sizing Recommendations use the same CPU and memory metrics shown here to suggest right-sized SKUs.
Orphaned Resources uses utilization patterns to flag resources that look unused.
Automated Scanning collects the metrics you read here. If a resource has no data, the scanner is the place to check.
