bsdhwmon

bsdhwmon is a program for FreeBSD for monitoring hardware sensors (fans, temperatures, voltages, chassis intrusion, and more) on commerical-grade server hardware.

bsdhwmon is developed with a very different mentality compared to other hardware monitoring software:

• Written with stability and production environments in mind
• Intended for use with server products (currently Supermicro, but can be extended to others that have proper SMBIOS identification data)
• Uses SMBus (smb(4) driver) exclusively, significantly decreasing risks and CPU usage compared to classic LPC I/O
• Based primarily on documentation provided by motherboard/server vendors, combined with documentation from chipset manufacturers
• Identifies hardware via strict SMBIOS data matching; device "probing" is avoided to minimise false positives and thus risks
• Full tested on both i386 and amd64 systems across multiple versions of FreeBSD (legacy and present-day)
• Written entirely in C
• No reliance on third-party libraries or tools (e.g. autotools, libtool, etc.)
• Very simple and clean code -- heavily commented, well-documented, built with -Werror -Wall and similar flags
• Occasionally tested under valgrind
