![]() If your Mac feels hot or the battery drains quickly, check the GPU activity. Note: If an Afterburner graphics card is connected to your Mac, choose Window > Afterburner History to display a graph that shows the Afterburner card usage. After setting up oh-my-zsh, you can specify the desired theme in the ~/.zshrc file, e.g. In the Activity Monitor app on your Mac, choose Window > GPU History. oh-my-zsh theme: Default theme robbyrussell.Unix shell + theming framework: zsh + oh-my-zsh Check out this awesome post about how to install these (similar steps on Ubuntu or Mac OS).Terminal emulator: iTerm2 Awesome Mac OS Terminal replacement with cool features such as grid tabs and more. Run ‘htop’ from the command line as usual on a Mac Installing Htop can take a while as it requires quite a few dependencies (zlib, openssl, perl, etc.), but Homebrew and MacPorts will take care of installing and downloading it for you.Saw some chatter on Twitter about this post which mentioned that I should have added information about the terminal theme I'm using here, since htop gets styled by the terminal and theme in use. unzip ~/Downloads/sample.zip > /dev/null &Įcho the PID of this background process with echo $!Ĭombine the two, and pass the pid of the process to top with top -p ` & echo $!`ĭouble Bonus: Style your editor for a more beautiful htop Run your command in the background and pipe the output to /dev/null so that it doesn't get printed on the command line while you are monitoring the CPU/memory usage, e.g. Ive installed htop-osx through Homebrew on my Mac, but in order to see all data for all processes, the formula tells me that I need to run htop as root, using sudo. How could I start monitoring these commands as soon as they were invoked? What can we do better However, I wanted to run commands which would exit within a few seconds, before I could run top to start monitoring them. Get the PID of the process with ps aux command which is generally available for both Linux and Mac. Conclusion In a mission-critical setting, top, htop, and atop are still the best / time-proven options. (not friendly to older distros like CentOS 7). Some of these processes seemed to bring my linux box to a screeching halt, and without instant resource monitoring I couldn't tell whether such a process was eating excessive RAM or CPU (or both?!) What people usually doĬonventionally, suggestions about process monitoring involve the following: Bashtop cons Uses more CPU and RAM compared to top and htop. I have been executing a lot of bash scripts and one-off processes on the linux command line recently, and was curious about how to monitor the CPU and memory usage of these processes as quickly as possible.
