With Mac, I have
istat that shows computer info (memory/cpu/network ...) in real time.
Does Ubuntu have a similar application?
You can get what you want with gkrellm -- it works out of the box, but you will probably want to tinker a bit to get the look and the info you're after.
You can install the basic application from the Software Center or via the command line, with
apt-get install gkrellm , but there are numerous plugins and themes available.
You can see the easily installed plugins with
apt-cache search gkrellm . Here's an extract:
gkrellm-bfm - system load plugin for gkrellm with a duck gkrellm-hdplop - A hard drive activity monitor GKrellM plugin gkrellm-ibam - Advanced battery monitor for laptops - gkrellm plugin gkrellm-leds - Keyboard LED monitor for GKrellM gkrellm-mailwatch - GKrellM plugin to watch mailboxes in multiple panels gkrellm-mldonkey - mldonkey plugin for gkrellm2 gkrellm-radio - FM radio tuner for GKrellM
And here's a themes directory (the last time I installed it, this is the site I used to find a theme I liked): muhri.net/gkrellm
Another option is conky
It is also installable from the Software center or via
apt-get. It is extremely configurable, and if you search, you'll find many screenshots of customized conky installations. (Here's one from conky pitstop .)
Looks like this question was asked when Unity was brand new and not many people were using it. None of the answers listed make use of the Unity menu bar, which imo is the only worthwhile place to have a system monitor.
Apparently the things in the menu bar are called "Application Indicators" and so far the closest thing I've found to iStat Menus is
indicator-multiload, explained here. In that thread there are also other examples of resource monitors, including one for hardware sensors.
It's not a direct equivalent, but you can add the System Monitor panel applet, which will show you real-time graphs of CPU, Memory, Network, etc. Right click on the panel Add To Panel and add the System Monitor applet. Then, right-click on the applet in the panel and in its preferences you can choose which resources to monitor. It doesn't have a drop-down menu like istat does, but it opens up the full system monitor when you click on it.
There's also indicator-sysmonitor
You can easily customize it.
