Logging errors is recommended best practice, even for production site. Checking those logs however might seem like a chore. The error monitoring brings all entries from error log on this page.<br /><br />
<ul>
<li>The log file is detected automatically from the configuration of the server</li>
<li>Only the end of file is read - no memory overflow issues, safe for large logs</li>
<li>Optimized to work card card-body bg-light even with very large log files</li>
