For more on how to customize Conky, please refer to the article: How to use Conky to make Linux more awesome.Ĭheck the free memory with the command line utilities Moreover, some themes created by other users make Conky very beautiful. But this utility is very flexible and can display many other system indicators. Of course, the default settings are very basic, so they often don't look very nice. Therefore, move it to the right: cp /etc/conky/nf ~/.conkyrc & sed -i 's/left/right/' ~/.conkyrc sed -i 's / left / right /' ~ /.

Please install it with the following command: sudo apt install conky-allīy default, it displays on the left side of the screen and will be superimposed on the application bar. It is always active and allows users to quickly see information about system resources at any time. ConkyĪnother popular solution for tracking system resources is Conky. You can use the same trick with htop or other utilities in the terminal window.

This will keep the window displayed all the time, even if you open a full screen program. Right-click the bar (title) at the top of the memory usage window and select Always on Top. Sometimes users may want to monitor memory usage when opening or using programs. In the Resources tab, users can view information about CPU load, memory usage and Swap (virtual RAM), as well as network activities. Not only to see memory usage, users can also right-click programs and change their CPU usage priority, forcing programs to close, etc. This application has 3 tabs to view information about processes, resources and file system. If it is not installed on the distribution you are using, you can install it with: sudo apt install gnome-system-monitor Gnome System Monitor

Check the free memory with the command line utilitiesīy default, Ubuntu includes an application called System Monitor.Anything less than that and you aren't using all the memory you have available. If you go above that regularly then you probably need more memory. The OS is still going to page things out when memory gets tight but the sweet spot has generally been to be around 80-85% of memory. My machine, which has been running for days, hovers between 70 and 80% at all times even though I have a couple instances of Visual Studio open, multiple browser apps and tabs, SQL Server running and miscellaneous other apps. The memory utilization can be a useful measurement of your system but it is not incredibly useful in determining the general stability these days. This is formally known as Superfetch and can be disabled if desired although there should be no reason to do so. Additionally, to make it look more responsive, the OS also tries to pre-fetch some things before you need them.
Thus on newer OSes you will see memory utilization is higher and apps are more responsive when swapping from background to foreground. Hence it keeps more stuff in memory rather than wasting the time paging it out (until needed). In the newer OSes where machines have far more GB of memory the OS has switched to being less aggressive with paging. So on the older OSes memory utilization was generally lower. The net result was more available memory for applications at the cost of having to page to/from disk.
On older OSes where memory was tight the OS was aggressive in moving stuff to the paging file when not needed. Starting around Win Vista MS changed how the OS uses virtual memory.
