# SLA-Driven Profiling and Planner Deployment Quick Start Guide

Complete workflow to deploy SLA-optimized Dynamo models using DynamoGraphDeploymentRequests (DGDR). This guide shows how to automatically profile models and deploy them with optimal configurations that meet your Service Level Agreements (SLAs).

> [!IMPORTANT]
> **Prerequisites**: This guide assumes you have a Kubernetes cluster with GPU nodes and have completed the [Dynamo Platform installation](/docs/kubernetes/installation_guide.md).

## Overview

The DGDR workflow automates the entire process from SLA specification to deployment:

1. **Define SLAs**: Specify performance requirements (TTFT, ITL) and model information in a DGDR Custom Resource
2. **Automatic Profiling**: The Dynamo Operator automatically profiles your model to find optimal configurations
3. **Auto-Deploy**: The system automatically deploys the optimal configuration that meets your SLAs

## What is a DynamoGraphDeploymentRequest (DGDR)?

A **DynamoGraphDeploymentRequest (DGDR)** is a Kubernetes Custom Resource that serves as the primary interface for users to request model deployments with specific performance and resource constraints. Think of it as a "deployment order" where you specify:

- **What** model you want to deploy (`model`)
- **How** it should perform (SLA targets: `ttft`, `itl`)
- **Where** it should run (optional GPU preferences)
- **Which** backend to use (`backend`: vllm, sglang, or trtllm)
- **Which** images to use (`profilingConfig.profilerImage`, `deploymentOverrides.workersImage`)

The Dynamo Operator watches for DGDRs and automatically:
1. Discovers available GPU resources in your cluster
2. Runs profiling (online or offline) to find optimal configurations
3. Generates an optimized DynamoGraphDeployment (DGD) configuration
4. Deploys the DGD to your cluster

**Key Benefits:**
- **Declarative**: Specify what you want, not how to achieve it
- **Automated**: No manual profiling job setup or result processing
- **SLA-Driven**: Ensures deployments meet your performance requirements
- **Integrated**: Works seamlessly with the Dynamo Operator

## Prerequisites

Before creating a DGDR, ensure:
- **Dynamo platform installed** with the operator running (see [Installation Guide](/docs/kubernetes/installation_guide.md))
- **[kube-prometheus-stack](/docs/kubernetes/observability/metrics.md) installed and running** (required for SLA planner)
- **Profiling PVC created** (see [Benchmarking Resource Setup](/deploy/utils/README.md#benchmarking-resource-setup#BenchmarkingResourceSetup))
- **Image pull secrets configured** if using private registries (typically `nvcr-imagepullsecret` for NVIDIA images)
- **Sufficient GPU resources** available in your cluster for profiling
- **Runtime images available** that contain both profiler and runtime components

### Container Images

Each DGDR requires you to specify container images for the profiling and deployment process:

**profilingConfig.profilerImage** (Required):
Specifies the container image used for the profiling job itself. This image must contain the profiler code and dependencies needed for SLA-based profiling.

**deploymentOverrides.workersImage** (Optional):
Specifies the container image used for DynamoGraphDeployment worker components (frontend, workers, planner). This image is used for:
- Temporary DGDs created during online profiling (for performance measurements)
- The final DGD deployed after profiling completes

If `workersImage` is omitted, the image from the base config file (e.g., `disagg.yaml`) is used. You may use our public images (0.6.1 and later) or build and push your own.

```yaml
spec:
  profilingConfig:
    profilerImage: "nvcr.io/nvidia/ai-dynamo/vllm-runtime:0.6.1"
  deploymentOverrides:
    workersImage: "nvcr.io/nvidia/ai-dynamo/vllm-runtime:0.6.1"  # Optional
```

## Quick Start: Deploy with DGDR

### Step 1: Create Your DGDR

Dynamo provides sample DGDR configurations in `benchmarks/profiler/deploy/`. You can use these as starting points:

**Available Sample DGDRs:**
- **`profile_sla_dgdr.yaml`**: Standard online profiling for dense models
- **`profile_sla_aic_dgdr.yaml`**: Fast offline profiling using AI Configurator (TensorRT-LLM)
- **`profile_sla_moe_dgdr.yaml`**: Online profiling for MoE models (SGLang)

Or, you can create your own DGDR for your own needs:

```yaml
apiVersion: nvidia.com/v1alpha1
kind: DynamoGraphDeploymentRequest
metadata:
  name: my-model-deployment  # Change the name
  namespace: default         # Change the namespace
spec:
  model: "Qwen/Qwen3-0.6B"     # Update to your model
  backend: vllm                # Backend: vllm, sglang, or trtllm

  profilingConfig:
    profilerImage: "nvcr.io/nvidia/ai-dynamo/vllm-runtime:0.6.1"  # Required
    config:
      sla:
        isl: 3000    # Adjust to your workload
        osl: 150     # Adjust to your workload
        ttft: 200    # Your target (ms)
        itl: 20      # Your target (ms)

      sweep:
        use_ai_configurator: false  # Set to true for fast profiling (TensorRT-LLM only)

  deploymentOverrides:
    workersImage: "nvcr.io/nvidia/ai-dynamo/vllm-runtime:0.6.1"  # Optional

  autoApply: true  # Auto-deploy after profiling
```

> [!TIP]
> For detailed explanations of all configuration options (SLA, hardware, sweep, AIC, planner), see the [DGDR Configuration Reference](/docs/benchmarks/sla_driven_profiling.md#dgdr-configuration-reference).

### Step 2: Apply the DGDR

The rest of this quickstart will use the DGDR sample that uses AIC profiling. If you use a different DGDR file and/or name, be sure to adjust the commands accordingly.

```bash
export NAMESPACE=your-namespace
kubectl apply -f benchmarks/profiler/deploy/profile_sla_aic_dgdr.yaml -n $NAMESPACE
```

The Dynamo Operator will immediately begin processing your request.

### Step 3: Monitor Progress

Watch the DGDR status:

```bash
# View status
kubectl get dgdr -n $NAMESPACE

# Detailed status
kubectl describe dgdr sla-aic -n $NAMESPACE

# Watch profiling job logs
kubectl logs -f job/profile-sla-aic -n $NAMESPACE
```

**DGDR Status States:**
- `Pending`: Initial state, preparing to profile
- `Profiling`: Running profiling job (20-30 seconds for AIC, 2-4 hours for online)
- `Deploying`: Generating and applying DGD configuration
- `Ready`: DGD successfully deployed and running
- `Failed`: Error occurred (check events for details)

> [!NOTE]
> With AI Configurator, profiling completes in **20-30 seconds**! This is much faster than online profiling which takes 2-4 hours.

### Step 4: Access Your Deployment

Once the DGDR reaches `Ready` state, your model is deployed and ready to serve:

```bash
# Find the frontend service
kubectl get svc -n $NAMESPACE | grep trtllm-disagg

# Port-forward to access locally
kubectl port-forward svc/trtllm-disagg-frontend 8000:8000 -n $NAMESPACE

# Test the endpoint
curl http://localhost:8000/v1/models
```

## DGDR Configuration Details

### Required Fields

| Field | Type | Description |
|-------|------|-------------|
| `spec.model` | string | Model identifier (e.g., "meta-llama/Llama-3-70b") |
| `spec.backend` | enum | Inference backend: `vllm`, `sglang`, or `trtllm` |
| `spec.profilingConfig.profilerImage` | string | Container image for profiling job |
| `spec.profilingConfig.config.sla` | object | SLA targets (isl, osl, ttft, itl) |

### Optional Fields

| Field | Type | Description |
|-------|------|-------------|
| `spec.deploymentOverrides.workersImage` | string | Container image for DGD worker components. If omitted, uses image from base config file. |
| `spec.autoApply` | boolean | Automatically deploy DGD after profiling (default: false) |
| `spec.deploymentOverrides` | object | Customize metadata (name, namespace, labels, annotations) and image for auto-created DGD |

### SLA Configuration

The `sla` section defines performance requirements and workload characteristics:

```yaml
sla:
  isl: 3000      # Average input sequence length (tokens)
  osl: 150       # Average output sequence length (tokens)
  ttft: 200      # Target Time To First Token (milliseconds, float)
  itl: 20        # Target Inter-Token Latency (milliseconds, float)
```

**Choosing SLA Values:**
- **ISL/OSL**: Based on your expected traffic patterns
- **TTFT**: First token latency target (lower = more GPUs needed)
- **ITL**: Token generation latency target (lower = more GPUs needed)
- **Trade-offs**: Tighter SLAs require more GPU resources

### Profiling Methods

Choose between **online profiling** (real measurements, 2-4 hours) or **offline profiling** with AI Configurator (estimated, 20-30 seconds):

```yaml
# Online Profiling (Default)
sweep:
  use_ai_configurator: false

# Offline Profiling (AI Configurator - TensorRT-LLM only)
sweep:
  use_ai_configurator: true
aic:
  system: h200_sxm
  model_name: QWEN3_32B
  backend_version: "0.20.0"
```

> [!NOTE]
> For detailed comparison, supported configurations, and limitations, see [SLA-Driven Profiling Documentation](/docs/benchmarks/sla_driven_profiling.md#profiling-methods).

### GPU Discovery

By default, the DGDR controller automatically discovers available GPU resources. Optionally specify preferences:

```yaml
spec:
  gpu:
    type: h200           # GPU type (e.g., h100, h200)
    count: 8             # Number of GPUs to use
    memoryGB: 141        # GPU memory in GB
```

### Advanced Configuration

#### Using Existing DGD Configs (Recommended for Custom Setups)

If you have an existing DynamoGraphDeployment config (e.g., from `components/backends/*/deploy/disagg.yaml` or custom recipes), you can reference it via ConfigMap:

**Step 1: Create ConfigMap from your DGD config file:**

```bash
kubectl create configmap deepseek-r1-config \
  --from-file=disagg.yaml=/path/to/your/disagg.yaml \
  --namespace $NAMESPACE \
  --dry-run=client -o yaml | kubectl apply -f -
```

**Step 2: Reference the ConfigMap in your DGDR:**

```yaml
apiVersion: nvidia.com/v1alpha1
kind: DynamoGraphDeploymentRequest
metadata:
  name: deepseek-r1
spec:
  model: deepseek-ai/DeepSeek-R1
  backend: sglang

  profilingConfig:
    profilerImage: "nvcr.io/nvidia/ai-dynamo/sglang-runtime:0.6.1"
    configMapRef:
      name: deepseek-r1-config
      key: disagg.yaml  # Must match the key used in --from-file
    config:
      sla:
        isl: 4000
        osl: 500
        ttft: 300
        itl: 10
      sweep:
        use_ai_configurator: true
      aic:
        system: h200_sxm
        model_name: DEEPSEEK_V3
        backend_version: "0.20.0"

  deploymentOverrides:
    workersImage: "nvcr.io/nvidia/ai-dynamo/sglang-runtime:0.6.1"

  autoApply: true
```

> **What's happening**: The profiler uses the DGD config from the ConfigMap as a **base template**, then optimizes it based on your SLA targets. The controller automatically injects `spec.model` into `deployment.model` and `spec.backend` into `engine.backend` in the final configuration.

#### Inline Configuration (Simple Use Cases)

For simple use cases without a custom DGD config, provide profiler configuration directly. The profiler will auto-generate a basic DGD configuration from your `model` and `backend`:

```yaml
profilingConfig:
  config:
    # SLA targets (required for profiling)
    sla:
      isl: 8000   # Input sequence length
      osl: 200    # Output sequence length
      ttft: 200.0 # Time To First Token (ms)
      itl: 10.0   # Inter-Token Latency (ms)

    # Hardware constraints (optional)
    hardware:
      min_num_gpus_per_engine: 2
      max_num_gpus_per_engine: 8
      gpu_type: h200_sxm

    # Profiling sweep settings (optional)
    sweep:
      force_rerun: false
```

> **Note**: `engine.config` is a **file path** to a DGD YAML file, not inline configuration. Use ConfigMapRef (recommended) or leave it unset to auto-generate.

#### Planner Configuration Passthrough
Add planner-specific settings. Planner arguments use a `planner_` prefix:

```yaml
profilingConfig:
  config:
    planner:
      planner_min_endpoint: 2
```

## Advanced Topics

### DGDR Immutability

DGDRs are **immutable** - if you need to update SLAs or configuration:

1. Delete the existing DGDR: `kubectl delete dgdr sla-aic`
2. Create a new DGDR with updated specifications

### Manual Deployment Control

Disable auto-deployment to review configurations before deploying:

```yaml
spec:
  autoApply: false
```

Then manually apply the generated DGD:

```bash
# Extract generated config
kubectl get dgdr sla-aic -n $NAMESPACE -o jsonpath='{.status.generatedConfig}' > my-dgd.yaml

# Review and modify if needed
vi my-dgd.yaml

# Deploy manually
kubectl apply -f my-dgd.yaml -n $NAMESPACE
```

### Relationship to DynamoGraphDeployment (DGD)

- **DGDR**: High-level "intent" - what you want deployed
- **DGD**: Low-level "implementation" - how it's deployed

The DGDR controller generates a DGD that:
- Uses optimal TP configurations from profiling
- Includes SLA planner for autoscaling
- Has deployment and engine settings tuned for your SLAs

The generated DGD is tracked via labels:
```yaml
metadata:
  labels:
    dgdr.nvidia.com/name: sla-aic
    dgdr.nvidia.com/namespace: your-namespace
```

## Troubleshooting

### Quick Diagnostics

```bash
# Check DGDR status and events
kubectl describe dgdr sla-aic -n $NAMESPACE

# Check operator logs
kubectl logs -n $NAMESPACE -l app.kubernetes.io/name=dynamo-operator --tail=100

# Check profiling job logs
kubectl logs -l job-name=profile-sla-aic -n $NAMESPACE
```

### Common Issues

| Issue | Quick Fix |
|-------|-----------|
| **DGDR stuck in Pending** | Check GPU availability: `kubectl get nodes -o jsonpath='{.items[*].status.allocatable.nvidia\.com/gpu}'` |
| **Image pull errors** | Verify secret exists: `kubectl get secret nvcr-imagepullsecret -n $NAMESPACE` |
| **Profiling fails** | Check job logs: `kubectl logs -l job-name=profile-sla-aic -n $NAMESPACE` |
| **SLA cannot be met** | Relax TTFT/ITL targets or add more GPUs |
| **DGD not deployed** | Verify `autoApply: true` in DGDR spec |
