lmmon

Display information gathered from MB power management controller

lmmon displays information gathered from a motherboard power management controller (e.g. LM78/79). Displayed values include fan speeds, motherboard temperature, and various voltages. By default it cycles once per second using a curses- based display. Currently, the /dev/smb0 interface is only supported in FreeBSD 3.3-STABLE (after 01 November 1999), 4.x, and 5.x; however, the /dev/io interface may work with many motherboards in FreeBSD 3.x and some non-LM78/79 motherboards. In addition, lmmon supports simple text output that can be easily used by external programs (e.g. UCD SNMP Daemon) for monitoring.
