How to collect HAProxy metrics

This article discusses how to collect metrics from HAProxy, a popular open-source load balancer. It explains two methods for accessing these metrics - via a status page and through Unix sockets. The status page provides a human-readable view of the performance of your load balancer but is static and ephemeral. On the other hand, communicating over the socket interface is more practical for scripting or automation purposes. Additionally, it introduces HATop, an unofficial third-party tool that can be used to manage and diagnose HAProxy services. The article concludes by recommending using a dedicated monitoring system like Datadog for production environments.
