Windows 7: If you like visual indicators for things like disk capacity, battery life, memory usage and speaker volume, and you like them prominent and easy to find, SuperbarMonitor puts easy to read indicators right on your Superbar.
If you've played around with system monitoring apps before and found them too technical or too overwhelmingly packed with widgets and data, you'll find a lot to like about Superbar Monitor. The indicators sit on your Superbar like program icons and give a broad overview like whether or not your CPU is pegging or you're chewing up a lot of RAM.
Each Superbar Monitor segment is an individual program so you only need to grab the modules you want. Don't want the battery meter because you're on a desktop? Don't even bother downloading it. The available monitoring modules are: battery, volume, disk space, CPU and memory. You can run multiple monitors for multiple disks by copying the disk monitor executable.
You can tweak the settings on each module to display an overlay icon (seen in the screenshot above with icons for disk, CPU and memory usage, as well as volume), a percentage, or no overlay icon at all. Each module has function specific tweaks too like what percentage is "critical" on the meters measuring system resources.
Note: If you want to take advantage of the more detailed mouse-over view — as seen above — don't minimise the Superbar applications, although you can leave them open behind the applications you're currently using. Windows 7 doesn't show the preview for minimised applications.
