CloudSnooze

CloudSnooze is a tool for automatically stopping idle cloud instances to save costs. The system monitors various system metrics (CPU, memory, network, disk I/O, user activity, GPU usage) and stops instances when they remain below specified thresholds for a defined period.

How It Works

CloudSnooze monitors system resource usage and automatically stops instances when all metrics remain below specified thresholds for a defined period (the “naptime”). This saves costs by ensuring you only pay for compute resources when they’re actually needed.

CloudSnooze Workflow

Key Components

Daemon (snoozed): A Go service that:
- Monitors system resources
- Verifies cloud provider permissions
- Tags instances when stopping (optional)
- Logs snooze events
- Stops instances via cloud provider APIs
CLI tool (snooze): A command-line interface for:
- Viewing system status
- Configuring thresholds and options
- Managing the daemon
- Viewing snooze history
GUI application (snooze-gui): An Electron-based interface for:
- Visual monitoring of system metrics
- Configuration management
- Historical data visualization
