# Kubernetes Trend All Clusters

**Purpose:** How the container estate has moved over time. A metric selector drives a single trend chart across all collected clusters, with the underlying values in a grid beneath.

## When to use it

- Establish a container growth rate for forecasting
- Confirm whether a consolidation or cleanup reduced the estate
- Separate genuine growth from a cluster being onboarded into collection
- Provide the baseline the budgeting forecast projects from

## Key areas and metrics

- **Metric selector.** A dropdown choosing what the chart plots and at what scope, for example all clusters together.
- **Chart.** Zoom presets of `1m`, `3m`, `6m`, `YTD`, `1y`, and `All`, a save control, an export menu, and a per-panel email action.
- **Grid.** The plotted values per collection date beneath the chart.

## Reading container growth

Container counts are far more volatile than VM counts, because scaling events, deployments, and restarts create and destroy containers continuously. A daily series will look noisy in a way a virtual machine trend never does, and that noise is normal.

So use longer windows than you would elsewhere. A month of this chart mostly shows deployment activity; a year shows whether the estate is actually growing. A step change that holds is an onboarding or a new workload; a spike that returns is a scaling event.

## Common actions

- **Start with All** to see the shape before narrowing.
- **Save the view** so each review reads the same window and metric.
- **Correlate step changes against cluster onboarding** before treating them as demand.
- **Pair with the budgeting report.** Growth in count alongside a flat average cost per container is healthy scaling.

## Tips

> An empty chart and a zero record count mean no container platform collector is configured. Check collection before investigating the report itself.
