HAProxy integration

The HAProxy integration provides load balancer monitoring at every layer: frontend, backend, and individual servers.


What it’s for	Monitoring traffic distribution, backend health, and capacity
Who uses it	Platform engineers, SREs, network teams managing high-traffic sites
Under the hood	Scrapes HAProxy’s stats interface for real-time visibility

Metrics collected

The integration collects metrics at every layer of the load balancer:

Frontend: Connections, requests, bytes
Backend: Server count, queue depth, response time
Server: Up/down, connections, health checks
Sessions: Current, limit, rate

What to know

Prebuilt dashboards: frontend, backend, server
Prebuilt alerts: backend health, queue depth
Health check visibility

HAProxy sits in front of your applications and distributes traffic, so when it’s unhealthy, everything behind it suffers. The integration gives you visibility at every layer.

Frontend metrics show incoming connections, requests, and throughput. Backend metrics aggregate your server pools with active server counts, queue depths, and response times, while server-level metrics drill into individual backends and health checks, often surfacing failures before users notice.

Setup means enabling HAProxy’s stats interface, which the integration scrapes. For high-traffic sites, queue depths and backend response times make this layer essential for capacity planning.
