server-stats.sh is a Bash script that provides a quick snapshot of your Linux server’s performance. It monitors CPU usage, memory stats, disk usage, and the top resource-consuming processes.

• ✅ CPU Usage: Real-time CPU utilization.
• ✅ Memory Stats: Total, used, and available memory, with usage percentages.
• ✅ Disk Usage: Disk space usage of the root (/) partition, with also percentage.
• ✅ Top Processes:
  • Top 5 processes by CPU usage
  • Top 5 processes by Memory usage
• ✅ Output to Log File: All the outputs of the bash script are saved to log in the form of server-stats-$(date '+%F_%H-%M-%S')

• 💻 CPU Usage - Uses top, grep, sed, and awk to extract CPU idle percentage and calculate actual usage.

• 🧠 Memory Usage - Parses /proc/meminfo to get: MemTotal, MemAvailable.

• 💾 Disk Usage - Uses df -h / and df / to get: Human-readable disk size and Used and available disk space in KB.

• 📌 Top Processes - Fetches the top 5 processes sorted by: CPU and Memory, through ps aux.

Make the script executable:

chmod +x server-stats.sh

Run the script:

./server-stats.sh

This script uses standard Linux tools:

• top
• awk
• sed
• grep
• bc
• ps
• df

No external packages required.

To monitor performance at intervals, set up a cron job like:

*/5* ** * /path/to/server-stats.sh >> /path/to/log.txt
