MenuMeters is a set of CPU, memory, disk, and network monitoring toolsfor MacOS X. Although there are numerous other programs which do thesame thing, none had quite the feature set I was looking for. Most werewindows that sat in a corner or on the desktop, which are inevitablyobscured by document windows on a PowerBook's small screen. Thosemonitors which used the menubar mostly used the NSStatusItem API, whichhas the annoying tendency to totally reorder my menubar on every login. The MenuMeters monitors are true SystemUIServer plugins (also known asMenu Extras). This means they can be reordered using command-drag andremember their positions in the menubar across logins and restarts. - The CPU Meter can display system load both as a total percentage, or broken outas user and system time. - The Disk Activity Meter displays disk activity to local disks on the system(anything that is a IOKit BlockStorage driver). - The Memory Meter can display current memory usage as either a pie chart,thermometer, history graph, or as used/free totals. - The Net Meter can display network throughput as arrows, bytes per second, and/oras a graph.
