Admin Bar Server Info displays essential server and environment information in a convenient dropdown menu on the WordPress admin bar.
The plugin is intentionally minimal and focused. It does not add settings pages, dashboard widgets, frontend output, or database storage. It simply shows key environment information in an organized dropdown menu accessible with one click from the admin bar for users with administrative permissions.
Displayed information includes:
PHP Information: 
– PHP version (full version with architecture bits) 
– PHP SAPI (Server API: mod_php, fpm, cgi, etc.) 
– Operating system (Linux, Windows, Darwin, etc.) 
– Max execution time 
– Max upload size
Memory Information: 
– Current memory usage and limit (with percentage) 
– WordPress memory limit (WP_MEMORY_LIMIT)
Server Information: 
– Server software (Apache, Nginx, LiteSpeed, IIS, Caddy, etc.) 
– Database version (MySQL or MariaDB with version) 
– Server IP address (with hostname) 
– Disk space (free/total with percentage used)
WordPress Information: 
– WordPress version
The information is visible only to users with the <code>manage_options</code> capability.
Key characteristics: 
– Dropdown menu – all information organized and accessible with one click 
– Icon-only display in admin bar for space efficiency 
– No configuration required – works immediately after activation 
– No frontend output – admin area only 
– No database tables or stored options 
– No external requests – all data gathered locally

My Server Info is a lightweight plugin that displays key server and site information in your WordPress admin panel. It shows details like:
<ul>
<li>PHP Version</li>
<li>MySQL Version</li>
<li>WordPress Memory Limit</li>
<li>PHP Execution Time</li>
<li>PHP Max Input Vars</li>
<li>PHP post_max_size</li>
<li>PHP upload_max_filesize</li>
<li>Site IP Address</li>
<li>Site Time and Timezone</li>
<li>CPU Usage (Average over 1 minute)</li>
<li>Disk Usage</li>
<li>Memory Usage</li>
<li>Server Uptime</li>
</ul>
PHP Version 
PHP Version indicates the current PHP version running on your server. WordPress relies on PHP for its core functionality, and using a supported version (7.4 or higher) ensures better performance, security, and compatibility with themes and plugins.
MySQL Version 
MySQL Version shows the version of the MySQL database your WordPress site is using. A compatible MySQL version (5.7 or higher) is essential for efficient data management, faster queries, and overall site stability.
WordPress Memory Limit 
WordPress Memory Limit defines the maximum amount of memory allocated for WordPress operations. A higher memory limit (256M or more) allows for smoother performance, especially when using resource-intensive plugins or handling large websites.
PHP Execution Time 
PHP Execution Time sets the maximum time a PHP script is allowed to run. Increasing this limit (300 seconds or more) helps prevent timeout errors during lengthy operations, such as bulk uploads or complex plugin processes.
PHP Max Input Vars 
PHP Max Input Vars specifies the maximum number of input variables your server can handle. Setting this to a higher value (3000 or more) ensures that large forms, like those in theme or plugin settings, function correctly without data loss.
PHP post_max_size 
PHP post_max_size determines the maximum size of data that can be submitted via POST requests. Setting this to at least 64M allows for uploading larger files through forms, such as media uploads or bulk data submissions, without encountering size limitations.
PHP upload_max_filesize 
PHP upload_max_filesize defines the maximum size of an individual file that can be uploaded through PHP. A higher limit (64M or more) is important for WordPress sites that handle large media files, plugins, or theme uploads, ensuring users can upload necessary files without restrictions.
Site IP Address 
Site IP Address displays your website’s public IP address. Knowing your site’s IP is useful for configuring DNS settings, troubleshooting connectivity issues, and enhancing site security through access controls.
Site Time and Timezone 
Site Time and Timezone reflect the current date, time, and timezone configured in your WordPress settings. Accurate time settings are crucial for scheduling posts, managing cron jobs, and ensuring consistency across your site’s content and activities.
CPU Usage (Average over 1 minute) 
CPU Usage provides an approximate percentage of CPU utilization averaged over the past minute. This helps in monitoring server performance and identifying potential issues related to high CPU load.
Disk Usage 
Disk Usage shows the percentage of disk space used on your server. Monitoring disk usage helps in managing storage resources effectively and preventing issues related to insufficient disk space.
Admin Bar Integration 
Under each progress bar, administrators can select checkboxes to add specific parameters to the WordPress admin bar. The available options are:
<ul>
<li>Memory Usage: Displays as <code>MEM: X%</code></li>
<li>CPU Usage: Displays as <code>AVG CPU: Y%</code></li>
<li>Disk Usage: Displays as <code>Disk: Z%</code></li>
</ul>
This feature allows quick access to essential server metrics directly from the admin bar, enhancing monitoring efficiency.
Server Uptime 
Displays the server’s uptime by reading the /proc/uptime file on Linux systems and formatting it into days, hours, minutes, and seconds. On unsupported systems (e.g., Windows), it will show “Unavailable”.
