Indicator-Sysmonitor (System Monitor Indicator) is a really interesting Ubuntu indicator because it allows you to display pretty much anything on the Unity (or GNOME) panel by using a simple command or a bash script.
(Speaking of Indicator-Sysmonitor: a recent update brought sensors support (make sure you install hddtemp and lm-sensors), but this post isn’t about that)
Currently there is no AppIndicator to display the actual network usage as in the actual values. We have Indicator Multiload but it only displays a graph so I wrote a script for Indicator-Sysmonitor to display the network upload/download speed as well as CPU and Memory usage (Indicator Sysmonitor already has CPU and Memory usage but if you want to use a script, you must get your script to display the CPU and Memory usage independently).
