Monitor HAProxy Metrics and Logs with OpenTelemetry [Step By Step Guide]

For extremely high throughput web applications, it is important to load balance the traffic across multiple servers. However, load balancing the traffic alone is not enough at times. The reverse proxy server that handles the workload needs to be performant, too. In our previous article , we discussed the NGINX reverse proxy server and understood how to monitor it. In this article, we set up monitoring for an even more performant reverse proxy server - HAProxy . In this tutorial, we cover: A Brief Overview of HAProxy A Brief Overview of OpenTelemetry How does OpenTelemetry Collector collect data? Pre-requisites Setting up OpenTelemetry Collector Monitoring with SigNoz Dashboard Reference: HAProxy metrics collected by OpenTelemetry Collector Conclusion If you want to jump straight into implementation, start with this prerequisites section. A Brief Overview of HAProxy HAProxy proudly calls itself a reliable and highly performant load-balancer. It does just one job - and does it very well.
