The NETGEAR Monitoring Plugin is a lightweight Go-based command-line tool designed to collect and report hardware and network metrics from NETGEAR devices via their API. It provides output using go-check, allowing easy integration into Icinga 2 checks. > [!WARNING] > > This plugin is intended only for use with NETGEAR AV Line devices. Use with other devices is not supported and may produce incorrect results.
