CPU Usage provides an approximate percentage of CPU utilization averaged over the past minute. It normalizes the load average by the number of CPU cores to estimate the CPU usage percentage. Please note that this is an approximate value and may vary based on server configurations.

Disk Usage indicates the percentage of disk space used on your server. Monitoring disk usage helps in managing storage resources effectively, ensuring that your site has sufficient disk space for operations like media uploads, plugin installations, and database growth.

post_max_size is a PHP configuration directive that sets the maximum amount of data (including file uploads) that can be sent via the POST method. This affects features like uploading media files, submitting forms, and any other operation that relies on POST requests. If you often handle large files or forms, you may need to increase the post_max_size value in your server’s PHP settings to avoid errors and ensure smooth uploads.
