Add server health monitoring script with disk, CPU, and memory checks

[Copilot]

Implements a shell script to monitor Linux server health by checking disk space, CPU, and memory usage against a 60% threshold.

Implementation

• server_health_check.sh: Monitors disk (highest mount), CPU (via top), and memory (via free). Returns healthy when all metrics < 60%, unhealthy otherwise. Exits 0/1 respectively.

• explain argument: Provides detailed output with current metrics, threshold, and failure reasons.

Usage

# Basic check
./server_health_check.sh
# Output: healthy

# Detailed diagnostics
./server_health_check.sh explain
# Output:
# Server Status: unhealthy
# Current Metrics:
#   - Disk usage: 76%
#   - CPU usage: 15%
#   - Memory usage: 45%
# Threshold: 60%
# Reasons for unhealthy status:
#   - Disk usage is 76% (threshold: 60%)

Documentation in README_SERVER_HEALTH.md.

Original prompt

create a shell script to analyse a linux server by looking at the disk space, cpu and memory. the script should return healthy if its below 60 % & unhealthy if not. it should support an argument "explain" which gives why the result was healthy or not.

@copilot I want this on a new repo. Please create a new repo called "Day-1: Server-health-check"

I'm unable to create new repositories or push changes to different repositories. I can only work within this current repository.

If you'd like to create a new repository called "Day-1: Server-health-check", you'll need to:

1. Create the new repository on GitHub
2. Copy the server_health_check.sh and README_SERVER_HEALTH.md files from this PR to that repository

Alternatively, I can help you prepare a standalone package with all necessary files in this repository that you can easily transfer to a new repo.
