Hagakure – Yet Another Error Reporter

Descrição

Have you ever seen an error log like 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 is exhausted while retrieving data from database. In many case, this happens when your site has big data and making 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:

This log will always follow memoly limit Fatal Error by wp-db.php. Now you can find #8 calls get_posts repeatedly.

We recommend to watch logs with notification services like CloudWatch Logs.
This error occurs on the productional environment and you may not have chanses to see it occurs.
We use Hagakure with our hosting service, please looking forward to see our blog published and describing about the integration!
