Step-by-step process to find idle cloud resources wasting money. Uses CPU, network, and disk metrics to identify resources running with zero utilization.

This is the practical version, the one you can follow in a single sitting. It starts read-only, touches no production resource by default, and every step is reversible, so there is no point at which you are committed to something you cannot undo. Budget about 10 minutes setup, results in 1 hour. Before you start you will want: Cloud account access with monitoring permissions; At least 14 days of metric history for best results; A ZopNight account.

## The steps

1. Connect your cloud accounts.
2. Wait for metric collection.
3. Review idle resource findings.
4. Triage and take action.

## Why this is safe to do today

The reason this is a low-stakes change is that nothing here is destructive. Scheduling stops and starts resources; it never deletes them, and your data persists across a stop exactly as it does across a normal reboot. Production is excluded by default, actions run in dependency order, and every state change is logged with what triggered it.

If you want the fuller context behind this task, the [FinOps](https://zop.dev/learn/finops) guide covers where it fits, and the [AWS EC2 scheduling](https://zop.dev/zopnight/aws/ec2) page shows the same loop applied to a specific resource.

## Getting started

Getting started is intentionally low-stakes:

- Connect your cloud provider with a read-only role. Nothing is scheduled or changed at this stage.
- Let ZopNight discover your non-production resources and review exactly what it found, filtered by account, region, and status.
- Create a schedule in your timezone and attach the non-production resources or groups you want it to cover.
- Watch the first cycle run, with Slack, Teams, or Google Chat notifications on every start, stop, and failure, then layer in idle cleanup and guided rightsizing.

Production stays excluded by default throughout, and because discovery and recommendations are read-only, you can prove the value before you enable a single action.

## Frequently asked questions

### What metrics determine if a resource is idle?

ZopNight analyzes CPU utilization, network in/out, disk read/write operations, and database connections over 14 days. A resource is flagged idle when all metrics consistently fall below minimal thresholds.

### Can idle detection create false positives?

Occasionally. Monitoring servers and bastion hosts may have low CPU but serve an important purpose. ZopNight lets you dismiss findings and exclude specific resources from future idle detection scans.
