Fatal Error Notify

Description

This plugin sends you an email notification whenever a fatal error (or other error level, configurably) is detected on your site.

Unlike traditional uptime monitoring services, which will only notify you if your entire site is down, this plugin can notify you when an error is detected on any page or process on your site.

Automatic plugin and theme updates often introduce problems that you aren’t aware of until they’re reported by your visitors. Fatal Error Notify lets you address these issues as they occur and before they cause significant problems.

  • Example email received when an error has been reported

Installation

Install it just like any other WordPress plugin:

Either: Upload the plugin files to the /wp-content/plugins/fatal-error-notify directory.
Or: Install the plugin through the WordPress plugins screen directly.

Then:
1. Activate the plugin through the ‘Plugins’ screen in WordPress
2. Use the Settings->Fatal Error Notify screen to configure notification settings

FAQ

How does the plugin send error notifications if my site is down?

Fatal Error Notify hooks into PHP’s “shutdown” function to send notifications right before the page stops loading. Even the dreaded “500 – Internal Server Error” still triggers PHP’s shutdown actions. Even if your site is completely offline, in most cases this plugin will be able to detect the error and notify you.

What’s in the Pro version

Fatal Error Notify Pro includes several additional features, like Slack notifications, the ability to hide the plugin settings, multisite support, logging of recorded errors, out of memory handling, the ability to pause individual notifications, and more.

Fatal Error Notify Pro also includes integrations with WP Fusion and Gravity Forms and can send notifications when errors are logged in those plugins.

Can I exclude specific errors?

Yes, you can use the filter fen_ingore_error, like so:

function fen_ignore_error( $ignore, $error ) {

    if( $error['file'] == '/home/username/public_html/wp-includes/class-phpass.php' ) {
        $ignore = true;
    }

    return $ignore;

}

add_filter( 'fen_ignore_error', 'fen_ignore_error', 10, 2 );

The $error variable is an array containing:

  • $error['type']: (int) The PHP error code
  • $error['message']: (string) The error message
  • $error['file']: (string) The path to the file that triggered the error
  • $error['line']: (int) The line number that triggered the error

I used Fatal Error Notify on a site that kept crashing and I couldn't find out what was going wrong. The plugin emails the PHP error message and that helped me track down the issue.
