Runs well on my FreeBSD 9.0 box. Thanks.

Just curious, is Glances the python script taking up 100% CPU and 1 GB of RAM in that screenshot?

Doubtful. I have glances running on a server at home updating on the default 1s timer, it uses 5% CPU. I should probably change that to a longer update interval, but that server doesn't do much processing so it's not a big problem.

You can also launch glances.py directly so if it is going to show up on the process list it will be as 'glances.py' and not just 'python'.

Seems to run decently on my Mac 10.8

Could you share how you got this to work on your Mac?

Earlier quoted context omitted.

Also it looks like the font the interface uses is a bit rounded. I'd recommend something blockier to prevent litigation.

explain?

Threadshitting about Apple.

If you like this, you might also like htop, which is similar but markedly faster at starting up.

Pretty sweet. One nitpick: any way of including disk wait?

I got this working by just installing pip and then entering "sudo pip install glances".

I have to say, I think this will replace htop for me on my mac. It's actually more useful than Activity Monitor is since it also shows network interfaces.

This looks good. For cpu and memory checks I find htop to be more lightweight and functionality wise is pretty good too. It doesn't show disk stats though, for which something like atop should be used.

The app looks really nice visually, a few points though:

except Exception: pass

is generally considered to be a code smell. The problem being that when you're catching all exception information and throwing it away you will never know what went wrong and where. If you're doing a try/except Exception nested inside another except Exception then I would humbly suggest that you really need to think about refactoring and restructuring.

Also, anywhere that you see a repeating pattern, you might be better off wrapping it in a function or method rather than typing it out each time. For example in your __update__ method starting at about line 400 you've got pretty much the same code in two places with just a variable different between the two.
