Load Balancer Monitoring: Metrics and Alerts
Summary
This guide explains how to monitor load balancers to surface degradations before users notice and treats the LB as a signal of overall application health. It lists essential metrics (healthy backends, target latency, 5xx rates, connections), details health-check configuration, and describes where to collect data across cloud (AWS, Azure, GCP) and on-premise (F5, NGINX, HAProxy) platforms. It recommends alert thresholds by severity, stresses correlating LB metrics with traces and logs for faster root-cause analysis, and provides an operational checklist to avoid common pitfalls. Implementing these practices reduces noisy NOC alerts, speeds diagnostics, and improves user experience and availability.
