What is WAN monitoring?
WAN monitoring tracks network performance across locations between offices, data centers, and cloud services. It measures bandwidth usage, latency, packet loss, and jitter to ensure applications work smoothly across distances.
Key aspects of WAN monitoring include:
Performance Monitoring: Tracking various metrics such as bandwidth usage, latency (delay in data transmission), packet loss (data that never reaches its destination), and jitter (variance in time it takes for packets to travel). These metrics help in understanding the quality of the network connection.
Fault Management: Detecting and diagnosing network issues to minimize downtime. This involves identifying failed devices or links, troubleshooting problems, and implementing solutions to restore connectivity.
Configuration Management: Keeping track of network device configurations and ensuring they are optimized for performance. This can also involve updating configurations to adapt to network changes or to enhance security.
Security Monitoring: Protecting the network from external threats such as hacking, phishing, and malware attacks. This involves monitoring for suspicious activity and ensuring that firewalls and other security measures are up to date and effective.
Traffic Analysis: Analyzing the types of traffic flowing over the network to identify usage patterns, bandwidth hogs, and potential security threats. This can help in capacity planning and ensuring that critical applications have the necessary resources.
SD-WAN Monitoring: As enterprises shift from legacy MPLS circuits to software-defined WAN architectures, monitoring SD-WAN overlays has become a core function of WAN monitoring. Tools must track tunnel health, jitter, latency, and packet loss across dynamic SD-WAN paths and, ideally, support multiple vendors (Cisco Viptela, Meraki, Fortinet, Palo Alto Prisma, and others) without requiring separate vendor-specific dashboards.
