I think that top is great application to monitor a Linux system. I really like it, but top doesn't look so good on Mac. I know that Mac have a system monitor to do it, but I prefer using a terminal.

I have installed htop by running:

brew install htop.

Here is what it looks like:

PID USER     PRI  NI  VIRT   RES   SHR S CPU% MEM%   TIME+  Command
    1 0          0   0     0     0     0 ?  0.0  0.0  0:00.00 (launchd)
   10 0          0   0     0     0     0 ?  0.0  0.0  0:00.00 (kextd)
   11 0          0   0     0     0     0 ?  0.0  0.0  0:00.00 (UserEventAgent)
   12 65         0   0     0     0     0 ?  0.0  0.0  0:00.00 (mDNSResponder)

The problem is that both CPU and MEM aren't returning the real values of either on my system.

Has anyone else experienced this? Or, could some one point me in the right direction?

I have the same problem so I check the recipe.

$ brew edit htop

Then I check this part of the recipe:

    def caveats; <<-EOS.undent
        For htop to display correctly all running processes, it needs to run as root.
        If you don't want to `sudo htop` every time, change the owner and permissions:
        cd #{bin}
        chmod 6555 htop
        sudo chown root htop
    EOS

So just type sudo htop and you will see CPU and MEM.

You can use brew info htop to see caveats content –  A.B Mar 29 '13 at 20:36
