Error Log Monitor

Description

This plugin adds a Dashboard widget that displays the latest messages from your PHP error log. It can also send you email notifications about newly logged errors.

Features

  • Automatically detects error log location.
  • Explains how to configure PHP error logging if it’s not enabled yet.
  • The number of displayed log entries is configurable.
  • Sends you email notifications about logged errors (optional).
  • Configurable email address and frequency.
  • You can easily clear the log file.
  • The dashboard widget is only visible to administrators.
  • Optimized to work well even with very large log files.

Usage

Once you’ve installed the plugin, go to the Dashboard and enable the “PHP Error Log” widget through the “Screen Options” panel. The widget should automatically display the last 20 lines from your PHP error log. If you see an error message like “Error logging is disabled” instead, follow the displayed instructions to configure error logging.

Email notifications are disabled by default. To enable them, click the “Configure” link in the top-right corner of the widget and enter your email address in the “Periodically email logged errors to:” box. If desired, you can also change email frequency by selecting the minimum time interval between emails from the “How often to send email” drop-down.

Reviews

So simple, yet, so helpful.

It is now in my "essential package" for new WordPress installs.

Also, I had an idea to include in the plugin features and the author developed it in a few days, so I'm really very satisfied.

Changelog

1.5.2

  • Fix a fatal error caused by a missing directory. Apparently, SVN externals don’t work properly in the wordpress.org plugin repository.

1.5.1

  • Added an option to ignore specific error messages. Ignored messages don’t show up in the dashboard widget and don’t generate email notifications, but they stay in the log file.
  • Added limited support for parsing stack traces generated by PHP 7.
  • Made the log output more compact.
  • Improved log parsing performance.
  • Fixed an “invalid argument supplied for foreach” warning in scbCron.

1.5

  • Added a severity filter. For example, you could use this feature to make the plugin send notifications about fatal errors but not warnings or notices.
  • Added limited support for XDebug stack traces. The stack trace will show up as part of the error message instead of as a bunch of separate entries. Also, stack trace items no longer count towards the line limit.

1.4

  • Added an option to send an email notification when the log file size exceeds the specified threshold.
  • Fixed a minor translation bug.
  • The widget now shows the full path of the WP root directory along with setup instructions. This should make it easier to figure out the absolute path of the log file.
