# Step 3: Monitoring the Metrics on the Lens AI Server.
### Lens AI monitoring server Components
The Lens AI Server comprises five major components:
1. Lens AI Sensor Data Handler: Manages sensor HTTP requests and stores incoming sensor data.
2. Lens AI Workers: Aggregates, transforms, and extracts metric data from sensor inputs for analysis.
3. Lens AI GraphQL Server: Provides a GraphQL endpoint to fetch the aggregated metrics, enabling flexible and efficient data retrieval.
4. Lens AI Monitoring Server: Uses Grafana to build interactive dashboards for monitoring key metrics.
5. Lens AI Database: Utilizes MongoDB to store sensor data and metrics for persistent and scalable storage.
