MotherBoard Monitor

## NAME

mbmon - MotherBoard Monitor

## SYNOPSIS

**mbmon** \[*options*\] \<seconds for sleep\> (default 5 sec)

This manual page documents briefly the **mbmon** command. This manual page was written for the Debian distribution because the original program does not have a manual page.

Recent motherboards have functionalities to monitor the CPU temperatures and the frequency of CPU cooling fans etc.  Although some programs utilizing these hardware monitoring facilities have been developed for the Microsoft Windows platforms, no programs seem to exist for PC-UNIX and the X Windows System platforms.

**mbmon** used at the command line reports the temperatures, voltages and rpm (rounds per minute) of cooling fans. It can also be used **remotely** via telnet, thanks to the "-P" option.
