## What it is
A Prometheus exporter that collects and exposes PostgreSQL server metrics over HTTP for scraping. It supports PostgreSQL 13-18, Docker deployment, and a beta multi-target probe mode for monitoring many databases from one instance.

## Use cases
- monitor postgresql database metrics with prometheus
- export postgres stats to prometheus
- monitor multiple postgres servers from one exporter
- scrape postgresql health and performance metrics
- set up database monitoring for postgres in docker
- track postgres query and replication metrics

## When to choose
- you run PostgreSQL and use Prometheus for monitoring
- you need a battle-tested, community-maintained postgres metrics exporter
- you want to monitor managed/SaaS postgres instances via multi-target probing

## When to avoid
- you use a different database than PostgreSQL
- you use a metrics system other than Prometheus without conversion
- you need deep APM-style query tracing rather than server metrics

## Facets
- artifact type: service
- maturity: active
- function: monitoring, http-server
- domain: databases, monitoring
- platform: go, self-hosted, cross-platform
- tags: prometheus, postgresql, exporter, metrics, database-monitoring, metrics-exporter, devops, linux, docker
