Ethernet Monitor

The Ethernet Connection Monitor provides a domain-focused view of wired link health. It captures key metrics such as link status, throughput, latency, and packet loss for a chosen interface, offering objective signals during troubleshooting and capacity planning.
Conceptually, the tool reads interface counters and, when enabled, active measurements, computes delta-based throughput in Mbps, estimates latency, and derives packet loss over the collection window. It normalizes data across counter wraps and interface changes to maintain stable time series.
Benefits include faster fault isolation, data-driven capacity checks, and consistent performance verification across on-premise devices and remote sites. Its value stems from explicit, machine-friendly outputs suitable for automation, alerting pipelines, and integration with monitoring stacks. Core features include per-interface selection, configurable poll intervals, delta calculations, and optional data export. Advanced options cover historical trends, jitter estimation, and compatibility with SNMP/NetDev sources. This tool helps network teams quantify health and demonstrate compliance with internal SLAs.
