Description

This script provides comprehensive server performance metrics including:

• Total CPU usage
• Memory usage (total, used, free, percentage)
• Disk usage (total, used, free, percentage)
• Top 5 processes by CPU usage
• Top 5 processes by memory usage
• OS version and system information
• System uptime and load average
• Currently logged in users
• Failed login attempts

Features

• Real-time server performance monitoring
• Easy-to-read formatted output
• No external dependencies (uses built-in Linux commands)
• Can be automated with cron jobs
• Supports log file generation

Requirements

• Linux operating system (tested on AlmaLinux 9.6)
• Bash shell
• Basic Linux commands: top, free, df, ps, uptime, who
• sudo access (optional, for failed login attempts)

Installation

1. Clone this repository:

git clone https://github.com/Shegxy69/Server-Performance-Stat.git
cd Server-Performance-Stat

2. Make the script executable:

chmod +x server-stats.sh

Usage

Basic Usage

Run the script as a normal user:

./server-stats.sh

With Sudo (to see failed login attempts)

sudo ./server-stats.sh

Sample Output

========================================
    SERVER PERFORMANCE STATS

1. Total CPU Usage:
-------------------
CPU Usage: 0.0%

2. Total Memory Usage:
----------------------
Total Memory: 1771 MB
Used Memory: 738 MB
Free Memory: 653 MB
Memory Usage: 41.67%

3. Total Disk Usage:

 ### Automated Monitoring with Cron

Schedule the script to run automatically:

### Run daily at 9:00 AM
```bash
crontab -e
# Add this line:
0 9 * * * /path/to/server-stats.sh > /path/to/logs/server-stats-$(date +\%Y\%m\%d).log 2>&1

Run every hour

0 * * * * /path/to/server-stats.sh > /path/to/logs/server-stats-$(date +\%Y\%m\%d-\%H\%M).log 2>&1
