MenuMeters: CPU, memory, disk, network monitoring menubar tools for Mac OS X

MenuMeters is a set of CPU, memory, disk, and network monitoring tools for MacOS X. The MenuMeters monitors are true SystemUIServer plugins (also known as Menu Extras). This means they can be reordered using command-drag and remember their positions in the menubar across logins and restarts.

• The CPU Meter can display system load both as a total percentage, or broken out as user and system time. It can also graph user and system load and display the load as a “thermometer”. The menu for the CPU Meter contains several pieces of information I like to have a single click away (uptime, load average, open Process Viewer, open Console).

• The Disk Activity Meter displays disk activity to local disks on the system (anything that is a IOKit BlockStorage driver). It is hotplug aware, and will show activity on FireWire and USB disks as they are mounted. The Disk Meter menu shows volume space details for local drives (it does not display mounted network volumes for speed reasons).

• The Memory Meter can display current memory usage as either a pie chart, thermometer, history graph, or as used/free totals. The Memory Meter menu shows a breakdown of current memory usage and VM statistics. The Memory Meter can optionally display a paging indicator light.

• The Net Meter can display network throughput as arrows, bytes per second, and/or as a graph. Both the arrows and the graph are scaled using a user-selected scaling factor and calculation. Scaling can be done on the basis of actual link speed reported by the network interface or peak traffic and can use one of several scaling calculations. The Net Meter menu shows current interfaces and their status. Interface information is gathered from the SystemConfiguraton framework and thus is MacOS X network location aware (to prevent interfaces from appearing in this menu see the FAQ).

  1. Activity Monitor is not necessarily easier to use, you have to launch Activity Monitor – and then click on the appropriate tab to see your CPU / Network / Disk / Memory Activity, as opposed to MenuMeters which is always instantly visible on your task bar.

  2. Agreed – good stuff. I like having the ability to instantly glance at the top of the screen and see what’s potentially bogging things down.

    (However, this is clearly another one of those periodic “infomercials” that seem to appear in lieu of actual news…)

  3. I’m with mugwump, it’s the first thing I install on ANY new Mac.

    And it’s a lot better than Activity Monitor, for one thing you can have it in your Menu Bar and it’s outta the way.

  4. Yeah… I love this program… lets you know what’s going on with your system at a glance… and having four cpu bars is a beautiful sight to behold ” width=”19″ height=”19″ alt=”smile” style=”border:0;” />

  5. Cool thing, but there’s too much crap in my Menu Bar now!

    12 things from Left:
    Spotlight
    iClock App Menu
    iClock
    International (Keyboard/Character Palette access)
    WeatherPop Advance
    Airport
    SwitchResX
    Bluetooth
    Timbuktu
    Battery Monitor
    Missing Sync Menu
    Stuffit Deluxe
    Synergy (iTunes control)

    That stuff already goes 1/3 of the way across my PowerBook’s 1440 pixel monitor. When certain applications are running, some of those Menu Bar Items disappear. With MenuMeters running, nothing’s left!

  6. I can’t wait for this intellitxt thing to take off… If it’s a hit, they’ll start adding more and more word links in all sorts of different colors that lead to even more sites that have nothing to do with the topic of the story…

    I do have to say, thank God that “download” link that leads to a ringtones site is there. I was reading this article and thinking, “This is pretty cool, a menu extra that lets me monitor my system, man, I wish I had more ringtones… Oh! Awesome there’s a link right here!!!”
