Command for RAM usage status on the server;
free -m
Let’s assume we performed the check and the swap is bloated.
To check what size the swap has been allocated;
swapon -s
We looked at the values; the swap is heavily used, or if you want to clean the swap, run the following 2 commands in order;
swapoff -a
swapon -a
The first command turns off the swap area, and the second one turns it back on. It gets cleaned.
