🚀 In this video, we will explore some essential tools with Linux for monitoring system performance and resource usage. These tools are invaluable for system administrators, developers, and anyone looking to understand and optimize their Linux environment.

Topics Covered:
1. top:
An interactive command-line tool that provides a real-time view of system processes, memory usage, CPU usage, and more. Learn how to navigate and interpret the data top provides to monitor your system effectively.

2. vmstat:
This tool reports information about processes, memory, paging, block IO, traps, and CPU activity. We'll show you how to use vmstat to get a snapshot of your system’s performance over time.

3. mpstat:
Part of the sysstat package, mpstat reports CPU usage for each processor. Discover how to monitor CPU performance and identify bottlenecks.

4. iostat:
Also part of sysstat, iostat provides statistics on CPU and input/output operations for devices and partitions. We'll guide you through using iostat to analyze disk I/O performance.

5. free:
This tool displays the amount of free and used memory in the system. Learn how to quickly assess your system’s memory status with free.

6. sar:
Another tool from sysstat, sar collects, reports, and saves system activity information. We'll show you how to configure and use sar for comprehensive system performance monitoring.

Scheduling scripts and commands is crucial for automation and efficient system management. We'll cover:

Setting up a cron job: Learn the syntax and format of crontab entries.
