# How to Update, roll back, and tear down safely

> Monitor Your Application

## Step 7:

Monitor and troubleshoot

### View Logs

**From the Web Interface:**

1. Open VMM dashboard at `http://localhost:9080`
2. Click on your deployment
3. Go to the **"Logs"** tab for real-time logs

**From the CLI:**

```bash theme={null}
# Stream logs in real-time
python3 vmm-cli.py --url http://localhost:8080 logs <vm-id> --follow

# Get last 100 lines
python3 vmm-cli.py --url http://localhost:8080 logs <vm-id> --lines 100
```

**Direct HTTP API:**

```bash theme={null}
curl 'http://<app-id>.app.example.com:9090/logs/<container_name>?follow=true&text=true&timestamps=true'
```

### Check Application Status

```bash theme={null}
# List all VMs and their status
python3 vmm-cli.py --url http://localhost:8080 lsvm --verbose

# List available images
python3 vmm-cli.py --url http://localhost:8080 lsimage
```

### VM Management

```bash theme={null}
# Start a VM
python3 vmm-cli.py --url http://localhost:8080 start <vm-id>

# Stop a VM
python3 vmm-cli.py --url http://localhost:8080 stop <vm-id>

# Remove a VM
python3 vmm-cli.py --url http://localhost:8080 remove <vm-id>
```

## Common Issues & Solutions

### Application fails to start

```bash theme={null}
# Check VM logs for errors
python3 vmm-cli.py --url http://localhost:8080 logs <vm-id>

# Verify VM status
python3 vmm-cli.py --url http://localhost:8080 lsvm -v
```

### Cannot access application URL

```bash theme={null}
# Check if VM is running
python3 vmm-cli.py --url http://localhost:8080 lsvm

# Test connectivity
curl -I https://<app-id>.example.com

# Check gateway VM logs (find gateway VM ID first)
python3 vmm-cli.py --url http://localhost:8080 logs <gateway-vm-id> --follow
```

### Attestation verification fails

1. Ensure the CVM is fully initialized
2. Verify TDX is enabled on your hardware
3. Check app endpoint is accessible via Unix socket
