# Building a chatbot with multiple AI providers using AI Configs: Monitoring and verification

> This guide teaches you how to build a simple AI-powered chatbot using LaunchDarkly AI Configs with multiple AI providers, including Anthropic, OpenAI, and Google. This page covers monitoring and verification.

## Part 4: Monitoring and verifying data

LaunchDarkly provides monitoring for AI Configs. Next, ensure your data flows correctly.

To learn more about monitoring capabilities, read [Monitor AI Configs](/home/ai-configs/monitor).

### Step 4.1: Understanding AI metrics

LaunchDarkly AI SDKs provide comprehensive metrics tracking to help you monitor and optimize your AI model performance. The SDK includes both individual `track*` methods and provider-specific convenience methods for recording metrics.

Available metrics include:

* **Duration**: Time taken for AI model generation, including network latency
* **Token Usage**: Input, output, and total tokens consumed (critical for cost management)
* **Generation Success**: Successful completion of AI generation
* **Generation Error**: Failed generations with error tracking
* **Time to First Token**: Latency until the first response token (important for streaming)
* **Output Satisfaction**: User feedback (positive/negative ratings)

#### Tracking Methods

The AI SDKs provide two approaches to recording metrics:

* **Provider-Specific Methods**: Convenience methods like `track_openai_metrics()` or `track_duration_of()` that automatically record duration, token usage, and success/error in one call
* **Individual Track Methods**: Granular methods like `track_duration()`, `track_tokens()`, `track_success()`, `track_error()`, and `track_feedback()` for manual metric recording

The `tracker` object is returned from your `completion_config()` call and is specific to that AI Config variation. Always call `config()` again each time you generate content to ensure metrics are correctly associated with the right variation.

For delayed feedback, such as user ratings that arrive after generation, use `tracker.get_track_data()` to persist the tracking metadata. Then, send feedback events later using `ldclient.track()` with the original context and metadata.

To learn more about tracking AI metrics, read [Tracking AI metrics](/sdk/features/ai-metrics).

### Step 4.2: Add comprehensive tracking

### Step 4.3: Testing complete monitoring flow

To test the monitoring flow:

<CodeGroup>
  ```bash title="Testing" theme={null}
      python simple_chatbot_with_targeting_and_tracking.py
  ```
</CodeGroup>

### Step 4.4: Verify data in Launch

Darkly

After running the monitored chatbot:

1. Navigate to **AI Configs**.
2. Select `simple-chatbot-config`.
3. View the **Monitoring** tab.

The monitoring dashboard provides real-time insights into your AI Config's performance:

<Frame caption="AI Config monitoring dashboard overview">
  ![AI Config monitoring dashboard overview](https://files.buildwithfern.com/https://launchdarkly.docs.buildwithfern.com/docs/e7cd2cdc9d217a588da2bc57f8c0f845adb856c86d654100d84c0608f99acd91/assets/images/tutorials/ai-configs-best-practices/monitoring_dashboard.png)
</Frame>

In the dashboard, you see several key sections:

* **Usage Overview**: Displays the total number of requests served by your AI Config, broken down by variation. This helps you understand which configurations are used most frequently.
* **Performance Metrics**: Shows response times and success rates for each interaction. A healthy AI Config should maintain high success rates (typically 95%+) and consistent response times.
* **Cost Analysis**: Tracks token usage across different models and providers, helping you optimize spending. Token tracking is essential for cost management and performance optimization. You can see both input and output token counts, which directly correlate to your AI provider costs.

<Frame caption="Detailed token usage and cost tracking metrics">
  ![Detailed token usage and cost tracking metrics](https://files.buildwithfern.com/https://launchdarkly.docs.buildwithfern.com/docs/f0db5f932a957cd36cc7c8fce50215f1d4e27b0e877ac756e2cc6165f14a8ce0/assets/images/tutorials/ai-configs-best-practices/metrics_tokens.png)
</Frame>

The token metrics include:

* **Input Tokens**: The number of tokens sent to the model, including prompt and context. Longer conversations accumulate more input tokens as history grows.
* **Output Tokens**: The number of tokens generated by the model in responses. This varies based on your `max_tokens` parameter and the model's verbosity.
* **Total Token Usage**: Combined input and output tokens, which determines your provider billing. Monitor this to predict costs and identify optimization opportunities.
* **Tokens by Variation**: Compare token usage across different variations to identify which configurations are most efficient for your use case.
