System Multiload and System Monitor AppIndicators, Ubuntu Oneiric and Natty

Application Indicators (shortly knows as AppIndicators) have replaced the old Gnome Panel applets in Unity starting from Ubuntu Natty.

System Multiload and System Monitor AppIndicators let you keep an eye on your system's resources. Multiload indicator provides you with graphed and a bit detailed overview of the used/available resources, whereas the System Monitor indicator is a simple and comparatively lightweight option.


Multiload Indicator

This indicator gives you a detailed overview of your system resources including Processor, Memory (RAM), Network, Swap, System Load and Harddisk in a graphed output. You, yourself, can choose which resources you want to monitor. It resembles very much the 'System Monitor' applet for Gnome Panel.

For installation in Oneiric, get to a Terminal and run:

sudo apt-get install indicator-multiload

For installation in Natty, you'd need to add its PPA as it wasn't included in the official repositories for Natty. From Terminal:

sudo add-apt-repository ppa:indicator-multiload/stable-daily
sudo apt-get update
sudo apt-get install indicator-multiload

PPA: https://launchpad.net/~indicator-multiload/+archive/stable-daily

Once installed, search the Dash for 'multiload' and start it.


You can customize it by clicking at the indicator anywhere in the top panel and going to 'Preferences'.


In the preferences dialog, tick the resources you want to monitor or untick the ones you don't want to. The widths of the graphs can also be customized and also the update interval. You can also choose custom colors for every graph output.


If you want to start it automatically when you log in, tick the box for 'Autostart' as shown in the screenshot above.

System Monitor AppIndicator

This AppIndicator simply displays the current Processor and Memory usage in the top panel. For installation in Ubuntu Oneiric or Natty, you would need to add its PPA. From Terminal:

sudo add-apt-repository ppa:alexeftimie/ppa
sudo apt-get update
sudo apt-get install indicator-sysmonitor

PPA: https://launchpad.net/~alexeftimie/+archive/ppa

Once installed, go to the Dash and search for 'sysmonitor' and open it.


For configuring it, click at the indicator in the top panel and go to 'Preferences'.


This is what you've got in the 'Preferences' dialog:


If you want to start this indicator automatically when you log in, tick the box for automatic startup as shown in the screenshot above.
