10. Understanding VPS Resource Limits and How to Monitor Usage Print

Overview:
Knowing your VPS resource limits helps you maintain performance and avoid service interruptions. This guide explains key resource metrics and how to monitor them.

Common VPS Resource Limits:

• CPU Cores: Determines how many processing threads your server can run simultaneously.

• RAM: Memory used by active applications and processes.

• Disk Space: Storage for files, databases, and system data.

• Bandwidth: Monthly data transfer allowance (upload + download).

• Inodes: The number of files and folders your server can hold.

How to Monitor Resource Usage:

1. Using Command Line Tools (Linux VPS):

• CPU and RAM Usage:

  bash

  CopyEdit

  top htop # if installed

• Disk Usage:

  bash

  CopyEdit

  df -h

• Inode Usage:

  bash

  CopyEdit

  df -i

• Network Traffic:

  bash

  CopyEdit

  iftop nload

2. Using Control Panel Tools:

• cPanel/WHM: Access "Server Information" or "Resource Usage" from the dashboard.

• CWP (Control Web Panel): Use the system monitor module to view live usage.

• Webuzo/DirectAdmin: Look under the server or system information section.

Tips for Managing Usage:

• Remove unused files and emails regularly.

• Optimize websites and databases.

• Use caching to reduce CPU/RAM load.

• Upgrade your VPS plan if frequently maxing out resources.
