server-stats Script

A script server-stats.sh that can analyse basic server performance stats

This Bash script provides an overview of system resource usage and information. It retrieves details about CPU, memory, disk usage, top resource-consuming processes, operating system version, logged-in users, and system uptime. It is useful for monitoring system performance and gaining quick insights into the current state of your machine.

Features

1. CPU Usage and Statistics

   • Displays total CPU/multiprocessor usage using the mpstat command.

2. Memory Usage

   • Shows the total memory usage in human-readable format using the free -h command.

3. Disk Usage

   • Outputs the disk usage across all mounted file systems in human-readable format with df -h.

4. Top 5 CPU-Consuming Processes

   • Lists the top 5 processes currently consuming the most CPU resources, extracted using the top command.

5. Top 5 Memory-Consuming Processes

   • Lists the top 5 processes consuming the most memory resources, also extracted using the top command.

6. Operating System Version

   • Displays the OS version by reading from /etc/*release.

7. Logged-In Users

   • Outputs the details of currently logged-in users using the w command.

8. Last Boot Time

   • Displays the time the system was last booted using uptime -s.

9. Current Uptime and Load Average

   • Shows the system uptime and load averages using the uptime command.

Notes

• Customizations: Feel free to modify the script to suit your needs. For example, adjust the number of processes listed or format the output differently.
• Dependencies: If any command is missing or unavailable, install the required package using your system's package manager (e.g., apt for Debian-based systems, yum for Red Hat-based systems).
• Permissions: Some commands may require root privileges to provide full details. Use sudo if necessary.
