Shell script to perform a Health Check of the Linux Server

In this post, I am sharing a shell script which will create a HTML output for a Linux OEL server health check.

You can change and Modify as per your needs. The script will generate a file named as server_health_report.html

[root@standby ~]# ls -ltr
total 8
-rw-r--r--. 1 root root 1177 Jun 22 04:25 health.sh
-rw-r--r--. 1 root root 3262 Jun 22 04:25 server_health_report.html

Script:

#!/bin/bash

# Output file for the health check report
OUTPUT_FILE="server_health_report.html"

# Function to generate formatted HTML report
generate_report() {
echo "<html>
<head>
<title>Server Health Check Report</title>
<style>
body {
font-family: Arial, sans-serif;
margin: 20px;
}
h1, h2, h3 {
color: #333;
}
table {
border-collapse: collapse;
width: 100%;
}
th, td {
padding: 8px;
text-align: left;
border-bottom: 1px solid #ddd;
}
</style>
</head>
<body>
