Network Monitoring: Benefiting You and Your Customers
Dennis Burgess, CTO of Link Technologies, emphasizes that effective network monitoring is foundational to ISP reliability and customer experience. He recommends deploying at least three core systems—a high-level overview tool (like The Dude), a deep monitoring platform (such as Zabbix), and external internet monitoring—to ensure visibility, rapid troubleshooting, and proactive alerting. A fourth system, BGP monitoring, becomes critical for networks with multiple upstreams to detect routing issues that may not trigger session failures. Together, these layered monitoring approaches improve uptime, reduce support load, and ensure a resilient, well-managed network.
