 # Monitoring
 
-Leverage OpenTelemetry to perform real-time monitoring of your LLM application using [OpenLIT](https://github.com/openlit/openlit). This tool helps you easily collect data on user interactions, performance metrics, and other key information, which can assist in enhancing the functionality and dependability of your GPT4All based LLM application.
+Leverage OpenTelemetry to perform real-time monitoring of your LLM application and GPUs using [OpenLIT](https://github.com/openlit/openlit). This tool helps you easily collect data on user interactions, performance metrics, along with GPU Performance metrics, which can assist in enhancing the functionality and dependability of your GPT4All based LLM application.
 
 ## How it works?
 
-OpenLIT adds automatic OTel instrumentation to the GPT4all SDK. It covers the `generate` and `embedding` functions, helping to track LLM usage by gathering inputs and outputs. This allows users to monitor and evaluate the performance and behavior of their LLM application in different environments. Additionally, you have the flexibility to view and analyze the generated traces and metrics either in the OpenLIT UI or by exporting them to widely used observability tools like Grafana and DataDog for more comprehensive analysis and visualization.

+### 3. (Optional) Enable GPU Monitoring
+
+If your application runs on NVIDIA GPUs, you can enable GPU stats collection in the OpenLIT SDK by adding `collect_gpu_stats=True`. This collects GPU metrics like utilization, temperature, power usage, and memory-related performance metrics. The collected metrics are OpenTelemetry gauges.
+
+```python
+from gpt4all import GPT4All
+import openlit
+
+openlit.init(collect_gpu_stats=True)  # Initialize OpenLIT monitoring
+
+model = GPT4All(model_name='orca-mini-3b-gguf2-q4_0.gguf')
