Ubuntu check cpu usage

As someone who manages Ubuntu servers, you'll need to know how much RAM your system has, and how much of the RAM is free to use.

You may even want to check the kind of RAM it is (DDR1 or DDR2).

In this tutorial, I'll show you how you can achieve the following in the terminal:

• Check the total RAM size
• Check the used and free RAM
• Type and speed of RAM

Check the total RAM size and the free RAM

You can use the free command to display the amount of free and used memory (RAM) in the system.

The option displays the output in a human-readable format.

Linux memory usage by process

Linux command to check ram size in gb

How to check memory usage in linux command

This means that you get to see the RAM size in GB, MB etc instead of in bytes.

You should see an output like this:

You have to focus on the row and the and columns.

As you can see, my Ubuntu server (running this site) has 1.9 GB of total RAM and 1.1 GB of available RAM.

This available RAM is the free RAM your system can use.

If your system is often running out of available RAM, you should consider adding swap space to your Ubuntu machine.
