Getting Started with the ‘sar Command’

Installation and Configuration

Before diving into the advanced functionalities of the sar command, it’s crucial to have it installed and properly configured on your system. On most Linux distributions, ‘sar’ is part of the Sysstat package. Use the following command to install Sysstat:

sudo apt-get install sysstat

Once installed, you need to enable data collection by editing the Sysstat configuration file, typically located at /etc/default/sysstat. Make sure the ENABLED flag is set to “true”.

Basic Usage of the Sar Command

With the basic setup complete, you can start using the sar command for system monitoring. Run the command with:

sar

This gives you a snapshot of the current CPU usage. However, ‘sar’ supports checking various performance metrics, including memory usage, network activity, and more.

Advanced System Monitoring with ‘sar’

Monitoring CPU Activity

The sar command excels in providing detailed CPU usage statistics. Use the following command for comprehensive CPU monitoring:

sar -u 1 5

This provides data about CPU usage every second for a period of five seconds. You can adjust the interval and count to suit your VPS management goals.

Memory Usage Analysis

Monitoring memory usage is critical for maintaining hosting performance, especially in a scalable hosting environment. The sar command offers a straightforward way to review memory statistics:
