Overview

An external dashboard visualization mechanism that displays Evidently metric results stored in PostgreSQL via Grafana panels.

Description

Grafana Visualization is an alternative monitoring approach where Evidently metric values are stored in PostgreSQL and visualized using Grafana dashboards. This pattern is used when organizations prefer Grafana's ecosystem over Evidently's built-in UI.

The workflow:

1. Evidently computes metrics via Report.run()
2. Metric values are extracted via Snapshot.dict() and inserted into PostgreSQL
3. Grafana connects to PostgreSQL as a data source
4. Dashboard panels query PostgreSQL for metric time series

Usage

Use when integrating Evidently monitoring into an existing Grafana-based observability stack. Requires PostgreSQL for storage and Grafana for visualization.

Theoretical Basis

This follows the extract-load-visualize pattern:

# Pseudocode
snapshot = report.run(data)
metrics = snapshot.dict()["metrics"]
db.insert("drift_metrics", values=metrics)
# Grafana SQL: SELECT timestamp, drift_score FROM drift_metrics ORDER BY timestamp
