System Monitor is an application for the menu bar of Mac OS X, designed to inform you unobtrusively about the activity of your computer. You can retrieve up-to-date technical data any time, like process load, CPU temperature, main memory consumption, storage space, disk activity, communication on network interfaces, etc. By positioning the app in the menu bar, as least screen real estate as possible will be wasted. The program monitors your system continuously and is readily available when you need it.
