Server resource monitoring helps detect overloads, errors, slow websites, and other issues.
Below are several methods for Linux servers (e.g., Ubuntu, Debian, CentOS) or servers with Plesk.

🔹 Option 1: Via Console (SSH)

🔸 CPU, RAM, Disk — top or htop Command

Connect to the server via SSH:

ssh root@your.server.ip

Then enter:

top

Or, if installed:

htop

📌 Explanation:

• CPU — processor load per core.

• Mem — RAM usage.

• Swap — swap memory usage.

• Load average — system load average (over 1, 5, and 15 minutes).

🔸 Disk:

df -h

Shows the size and usage of each partition.

🔹 Option 2: Using the free Command for RAM

free -h
