enable_metrics: true
metrics_retention: 168  # hours (7 days)

# Alerting configuration
alerting:
  enabled: true
  cpu_threshold: 80.0    # percentage
  memory_threshold: 90.0 # percentage
  disk_threshold: 85.0   # percentage
  notification_method: "console"  # console, email, webhook

🐛 Troubleshooting

Common Issues

Docker Connection Failed

Error: failed to create Docker client: Cannot connect to the Docker daemon

Solution: Ensure Docker is running and you have proper permissions:

# Start Docker service
sudo systemctl start docker

# Add user to docker group
sudo usermod -aG docker $USER

# Log out and back in, or run with sudo
sudo docker-container-manager list

Permission Denied

Error: permission denied while trying to connect to the Docker daemon socket

Solution: Either run with sudo or fix Docker permissions:

# Check docker group membership
groups $USER

# Run with sudo
sudo docker-container-manager list

Build Errors

go: missing import: module not found

Solution: Update dependencies:

go mod tidy
