Why RAM usage is not displayed in the analytics dashboard?
✓ Best Answer
I suggest looking into Linode Longivew for additional metrics such as RAM usage. It's pretty simple to install and can even be configured to monitor Nginx, Apache, and MySQL.
Although I don't know for sure, RAM usage is very dynamic (and it's coupled with swap usage)…making the value displayed on a website not very useful.
The top utility comes with Linux. It will give you a much more comprehensive display of RAM usage that updates much more quickly.
The htop utility (the one I like) is also available and will give you much more information. What you see is very customizable. You have to install htop.
