One tool made especially to gather metrics from HAProxy instances and make them available for Prometheus monitoring is the Prometheus HAProxy Exporter. At Bobcares, with our Server Management Service, we can handle your issues.

Prometheus HAProxy Exporter: An Introduction

A program called the Prometheus HAProxy Exporter was created expressly to gather metrics from HAProxy instances and make them accessible for Prometheus monitoring. The exporter takes metrics and data from a Unix socket or HAProxy’s built-in statistics page, exposing them in a format that Prometheus can store as well as scrape for additional analysis and visualisation.

Prometheus HAProxy Exporter: Working

1. Data Collection:

By connecting to HAProxy instances, the HAProxy Exporter gathers a variety of metrics, such as data regarding frontend and backend servers, request rates, response times, error rates, and more. In order to accomplish this, it either connects directly to the Unix socket, if enabled, or uses the statistics page that HAProxy provides.

2. Metric Exposition:

The exported metrics are converted into a Prometheus-readable format by the exporter. Because each statistic has a name attached to it, data querying and filtering are made versatile.

3. Prometheus Scraping:

The HTTP endpoint of the Exporter is set up for Prometheus in order to regularly scrape data from. The metrics are sent by the exporter’s HTTP server over a designated path, often /metrics.

4. Storage and Analysis:

Then, the metrics that are gathered are kept in Prometheus’ time-series database. So, we may write queries in PromQL to get and examine the data over time. With programs like Grafana, these queries may be used for dashboard construction, alerting, and monitoring.
