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 -Walland similar flags
- Occasionally tested under valgrind
At this time, only a small set of Supermicro hardware is supported. For an official list of supported hardware and models, please see doc/supported.md.
