System Resource Monitoring with Linux CLI Tools
📖 Scenario: You are a system administrator who needs to check the health of a Linux server. You want to monitor memory usage, system uptime, and CPU activity using simple Linux commands.
🎯 Goal: Learn to use free, uptime, and vmstat commands to monitor system resources and understand their outputs.
📋 What You'll Learn
Use the free command to check memory usage
Use the uptime command to check how long the system has been running
Use the vmstat command to check CPU and memory statistics
💡 Why This Matters
🌍 Real World
System administrators regularly check server health to prevent crashes and performance issues by monitoring memory, uptime, and CPU usage.
💼 Career
Knowing these commands is essential for Linux system administrators, DevOps engineers, and anyone managing servers to ensure smooth operations.

1
Check Memory Usage with free
Run the free -m command to display memory usage in megabytes.
Linux CLI
Need a hint?

The -m option shows memory in megabytes, which is easier to read.

2
Check System Uptime with uptime
Run the uptime command to see how long the system has been running and the load averages.
Linux CLI
Need a hint?

The uptime command shows the current time, how long the system has been running, and load averages.

3
Monitor CPU and Memory with vmstat
Run the vmstat 1 2 command to display CPU and memory statistics twice with a 1-second interval.
Linux CLI
Need a hint?

The vmstat 1 2 command shows system stats twice, one second apart, to observe changes.

4
Display All Monitoring Outputs
Run all three commands in sequence: free -m, uptime, and vmstat 1 2 to see memory, uptime, and CPU stats.
Linux CLI
Need a hint?

Run all commands one after another to get a full picture of system resources.
