Grafana SQL Alerts — Examples & 2025 Guide

Grafana SQL alerts empower you to monitor critical metrics, trigger notifications, and detect anomalies in real-time. Whether you're managing infrastructure, SaaS platforms, or analytics dashboards, setting up robust SQL-based alerts ensures rapid response to issues—before they affect your users.

However, writing the right SQL queries for alerting in Grafana can be challenging, especially when nuanced conditions, time windows, and multiple KPIs are involved. This is where AI2sql platform makes a difference. With AI2sql, you describe your monitoring need in natural language (e.g., "Alert if error count exceeds 50 in the last 10 minutes"), and get an accurate SQL statement ready to plug into your Grafana panel—no manual coding or deep SQL expertise required.

How Grafana SQL Alerts Work

• Alert Rules: Defined within Grafana, typically by writing SQL queries that return time series or value triggers.

• Query Sources: Work with MySQL, PostgreSQL, MS SQL, and other supported databases.

• Notification Channels: Integrate with Slack, email, PagerDuty, and more for automated incident response.

Real-World Examples: SQL Queries for Grafana Alerts

1. High Error Rate Alert

SELECT
  COUNT(*) AS error_count
FROM logs
WHERE log_level = 'ERROR'
AND timestamp > NOW() - INTERVAL 10 MINUTE;

2. Database Latency Threshold

SELECT
  MAX(duration_ms) AS max_query_time
FROM query_logs
WHERE executed_at > NOW() - INTERVAL 15 MINUTE;

3. User Sign-Up Drop-Off
