OPNSense Monitoring with Prometheus, Alloy and Grafana

Learn to implement comprehensive monitoring for OPNSense firewalls by setting up a complete observability stack with Prometheus, Grafana Alloy, and Grafana dashboards. Configure Node Exporter to collect essential system metrics from your OPNSense firewall, then deploy and configure Grafana Alloy as a telemetry collector to scrape both system and API metrics. Set up API exporters to gather detailed firewall statistics and network data, enabling deep visibility into firewall performance and security events. Build powerful Grafana dashboards that correlate system metrics with firewall-specific data, allowing you to monitor traffic patterns, detect anomalies, and troubleshoot network issues effectively. Master the configuration of metric collection pipelines, dashboard creation techniques, and best practices for monitoring network infrastructure components in enterprise environments.
