Network monitoring is crucial for organizations to prevent service disruptions and revenue loss due to network outages, which are increasingly common due to the complexity and size of modern networks. Grafana and Prometheus offer robust solutions for monitoring network performance, with Grafana providing visualization capabilities and Prometheus handling data collection and alerting. The Simple Network Management Protocol (SNMP) is a key method used to monitor network devices, and Grafana Labs offers an SNMP mixin that integrates with Prometheus, allowing users to configure dashboards and alerts based on specific network metrics. These tools enable network engineers to diagnose and resolve issues quickly by visualizing data such as CPU load, memory utilization, and bandwidth use, thereby enhancing proactive network management. The guide encourages users to explore Grafana Cloud for an accessible entry point into metrics, logs, and dashboards, offering a free tier and various plans to suit different needs.
