README

This module disables various log attempts of the Magento core, improving performance slightly.

Usage

Just install the module and it will disable some logging.

The following logs will be disabled when the Yireo_DisableLog module is installed:

• In the customer module the LogLastLoginAtObserver class logs a succesfull login, responding to the event customer_login.
• In the customer module the LogLastLogoutAtObserver class logs a succesfull logout, responding to the event customer_logout.

The following tables are supposed to be free from new insertions:

• customer_log
• customer_visitor

Note that this disables the feature of Customers -> Now Online.

Under Magento 1, this module also prevented information to be logged to report_* tables. This has changed in Magento 2: You can disable the setting reports/options/enabled (Reports > General Options > Enable Reports) for this.

Installation

Instructions for using composer

Use composer to install this extension. First make sure that Magento is installed via composer, and that there is a valid composer.json file present. Next, install our module using the following command:

composer require yireo/magento2-disablelog2

Next, enable the new module in Magento:

./bin/magento module:enable Yireo_DisableLog2
./bin/magento setup:upgrade

Check whether the module is succesfully installed in Admin > Stores > Configuration > Advanced > Advanced.

Done.

Instructions for manual copy

We recommend composer to install this package. However, if you want a manual copy instead, these are the steps:

• Upload the files in the source/ folder to the folder app/code/Yireo/DisableLog2 of your site
• Run php -f bin/magento module:enable Yireo_DisableLog2
• Run php -f bin/magento setup:upgrade
• Flush the Magento cache
• Done

Backgrounds

The Magento 2 core has an excellent logging system: Every time that a customer logs in or out, his/her details are logged. This might lead to a big database size over time. Not everybody wants this: There are numerous threads discussing the periodic cleaning of those tables using the SQL statement TRUNCATE. But this is only part of the problem.

Besides filling up the database, this logging also causes various extra SQL INSERT statements to be made for every pageload. If you have a busy site, this certainly has an impact on database-performance.

Now, if you're relying on those Magento 2 log statistics, you'll just have to accept this as a fact. However, if you're using other external services like Piwik or GoogleAnalytics, this Magento logging is actually an unwanted feature.

Our extension

Our extension gives you the power to disable all this Magento 2 logging: Either for all requests being made, or only for search-robots. It disables logging, but also disables the autoincrement flag for certain search patterns: The latter is interesting if you are interested in what your real-life customers are actually searching for, while by default search engines mess up these statistics.

Technical specifications

This extension makes use of interceptors (aka plugins) to override various Magento 2 core classes. See the etc/di.xml file for details.

PWA compatibility

This extension changes core behaviour and has no need to become compatible with PWA.
