## What it is
An official Prometheus exporter that scrapes MySQL and MariaDB server metrics and exposes them in Prometheus format over HTTP. It supports single-instance and multi-target probing modes with configurable authentication modules.

## Use cases
- monitor mysql server metrics with prometheus
- export mariadb performance metrics to prometheus
- scrape mysql connection and query statistics
- monitor multiple mysql instances from one exporter
- set up alerting on mysql slow queries and replication lag

## When to choose
- you run Prometheus and need MySQL/MariaDB metrics
- you want an official, maintained exporter with multi-target support
- you monitor MySQL >= 5.6 or MariaDB >= 10.3

## When to avoid
- you don't use Prometheus or a Prometheus-compatible monitoring stack
- you need metrics from other databases like PostgreSQL or MongoDB
- you run very old MySQL versions below 5.6

## Facets
- artifact type: service
- maturity: active
- function: monitoring
- domain: databases, monitoring
- platform: cross-platform, go
- tags: prometheus-exporter, mysql, mariadb, database-monitoring, multi-target, metrics-exporter, devops, linux, docker
