ttyload is a lightweight utility which is intended to offer a color-coded graph of load averages over time on Linux and other Unix-like systems. It enables a graphical tracking of system load average in a terminal (“tty“).
n
It is known to run on systems such as Linux, IRIX, Solaris, FreeBSD, MacOS X (Darwin) and Isilon OneFS. It is designed to be easy to port to other platforms, but this comes with some hard work.
n
Some of its notable features are: it uses fairly standard, but hard-coded, ANSI escape sequences for screen manipulation and colorization. And also comes with (but doesn’t install, or even build by default) a relatively self-contained load bomb, if you want to view how things work on an otherwise unloaded system.
