Linux and Windows Monitoring with SNClient
summary
SNClient is a complete Go rewrite of the classic NSClient designed as a drop-in replacement for Icinga/Nagios/Naemon using NRPE, REST and a built-in Prometheus path. It ships managed exporters (node_exporter/windows_exporter) that the agent starts and restarts, keeps a ~20MB binary with modest memory use, and offers packages, TLS updates and certificate management. The repo shows ~2,700 commits from 12 contributors, 36 built-in checks, configurable raw-value outputs and filters, and about ~3,000 known installs in production. Managed node/windows exporter behavior and required_password enforcement are practical changes that already work.
