## Daily Operations

### Check Service Health
```bash
# Via Portainer
open http://atlantis.vish.local:9000

# Via SSH
ssh admin@atlantis.vish.local
docker ps --format "table {{.Names}}\t{{.Status}}\t{{.Ports}}"
```

### Check Disk Usage
```bash
# SSH to Atlantis
ssh admin@atlantis.vish.local

# Synology storage manager
sudo syno-storage-usage -a

# Or via Docker
docker system df
```

### View Logs
```bash
# Specific service
docker logs vaultwarden

# Follow logs
docker logs -f vaultwarden
```

## Common Issues

### Service Won't Start
1. Check if port is already in use: `netstat -tulpn | grep <port>`
2. Check logs: `docker logs <container>`
3. Verify volume paths exist
4. Restart Docker: `sudo systemctl restart docker`

### Storage Full
1. Identify large files: `docker system df -v`
2. Clean Docker: `docker system prune -a`
3. Check Synology Storage Analyzer
4. Archive old media files

### Performance Issues
1. Check resource usage: `docker stats`
2. Review Plex transcode logs
3. Check RAID health: `sudo mdadm --detail /dev/md0`
