Title: Hagakure – Yet Another Error Reporter Author: TAROSKY INC. Published: మే 10, 2019 Last modified: మార్చి 28, 2025 --- Search plugins ![](https://ps.w.org/hagakure/assets/banner-772x250.jpg?rev=2085221) This plugin **hasn’t been tested with the latest 3 major releases of WordPress**. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress. ![](https://ps.w.org/hagakure/assets/icon-256x256.png?rev=2085221) # Hagakure – Yet Another Error Reporter By [TAROSKY INC.](https://profiles.wordpress.org/tarosky/) [Download](https://downloads.wordpress.org/plugin/hagakure.1.3.2.zip) * [Details](https://te.wordpress.org/plugins/hagakure/#description) * [Reviews](https://te.wordpress.org/plugins/hagakure/#reviews) * [Installation](https://te.wordpress.org/plugins/hagakure/#installation) * [Development](https://te.wordpress.org/plugins/hagakure/#developers) [Support](https://wordpress.org/support/plugin/hagakure/) ## Description Have you ever seen an error log like the one below? > PHP Fatal error: Allowed memory size of xxxxxx bytes exhausted (tried to allocate > xxx bytes) in /var/www/wordpress/wp-includes/wp-db.php on line 2007 This means that [PHP memory limit](https://www.php.net/manual/en/ini.core.php#ini.memory-limit) is exhausted while retrieving data from a database. In any case, this happens when your site has big data and makes insane loops inside. But we want to know that **which plugin tried to retrieve data?** Hagakure adds extra information to error.log file when `wp-db.php` causes memory limit error: ``` [08-May-2019 10:28:37 UTC] wpdb Error Backtrace: #1 Kunoichi\Hagakure\DbLogger->filter_query() /app/public/wp-includes/class-wp-hook.php Line 286 #2 WP_Hook->apply_filters() /app/public/wp-includes/plugin.php Line 208 #3 apply_filters /app/public/wp-includes/wp-db.php Line 1871 #4 wpdb->query() /app/public/wp-includes/wp-db.php Line 2579 #5 wpdb->get_results() /app/public/wp-includes/class-wp-query.php Line 2979 #6 WP_Query->get_posts() /app/public/wp-includes/class-wp-query.php Line 3387 #7 WP_Query->query() /app/public/wp-includes/post.php Line 1961 #8 get_posts /app/public/wp-content/plugins/hagakure/hagakure.php Line 34 #9 {closure} /app/public/wp-includes/class-wp-hook.php Line 286 #10 WP_Hook->apply_filters() /app/public/wp-includes/class-wp-hook.php Line 310 #11 WP_Hook->do_action() /app/public/wp-includes/plugin.php Line 465 #12 do_action /app/public/wp-includes/template-loader.php Line 13 #13 require_once /app/public/wp-blog-header.php Line 19 #14 require /app/public/index.php Line 17 #15 URI: /?p=1 ``` This log will always follow the memory limit Fatal Error by `wp-db.php`. Now you can find `#8` calls `get_posts` repeatedly. We recommend watching logs with notification services like [CloudWatch Logs](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html). This error occurs in the productional environment, and you may not have a chance to see it occurs. We use Hagakure with our [hosting service](https://hosting.kunoichiwp.com/), please look forward to seeing [our blog published](https://kunoichiwp.com/blog) and describing the integration! This plugin also adds debug backtrace to error logs. To modify the error level to a detailed backtrace, define the constant in `wp-config.php` or somewhere else: ``` define( 'HAGAKURE_ERROR_LEVEL', E_NOTICE | E_USER_WARNING | E_WARNING | E_USER_ERROR ); ``` Besides that, if `SAVEQUERIES` is set `true`, the slow query log will be logged with PHP debug backtrace. This helps you to debug. ### Acknowledgements The base text for dummy content is “Three Ghost Story” by Charles Dickens.
