How to manage & view resouces that are acquired by your Linode

Prerequisite: You know how to set up a Linode , and it is running

Checking Disk Usage

You can see the disk usage of all the volumes you've mounted through this command (df -h)

The most important one is the one with '/' also known as root filesystem or rootfs. Here I can see I've used 237G out of 358G available and have 121G available. This can be handy if you see your server suffering from memory issues

There's a tool which can help us take a closer look into what is occupying space : ncdu (not installed by default)

Command = sudo ncdu -x / -x flag tells to just scan the local filesystem and ignore the rest , and / is the target directory, from where it starts to scan (also has subdirectories) Now You can use your arrow and enter keys to navigate through your file system and can see in the brackets how much disk is that thing occupying.

Checking System Memory

Command = free -m Here, you can see I have about 1.7 Gigs of Memory left available

Checking CPU usage

An Important command is : uptime Tells you how long the server has been up, and tells you the load average. There are 3 numbers denoting Load averages at 1 minute, 5 minute and 15 minute respectively
