Documentation

Overview

Package haproxy implements a backend/server health check for HAProxy, reading the CSV stats export over HTTP (the `;csv` stats endpoint). It flags servers that are DOWN (BAD) or in MAINT/DRAIN/NOLB (WARN), backends with no available server (BAD), and — optionally — session usage near the limit.

Only the read-only stats page is consumed; the check never mutates HAProxy.
