[Magento] Optimize magento database by Cleaning log

Written by

Optimize magento database Log Cleaning

Magento maintains several tables for logging. These tables log things such as customer accesses and which products have been compared. Magento has a mechanism for cleaning these logs regularly, but unfortunately this feature is disabled by default and most customers do not turn it on. There are three ways to clean out these tables: via Log Cleaning in the Magento Admin, via log.php in the ../shell directory, and manually via phpMyAdmin or mysql client.

The following tables are managed by Magento’s Log Cleaning function:

log_customer
log_visitor
log_visitor_info
log_url
log_url_info
log_quote
report_viewed_product_index
report_compared_product_index
report_event
catalog_compare_item< !−−more−−>

Let ‘s execute this SQL to clear and optimize them

TRUNCATE dataflow_batch_export;
TRUNCATE dataflow_batch_import;
TRUNCATE log_customer;
TRUNCATE log_quote;
TRUNCATE log_summary;
TRUNCATE log_summary_type;
TRUNCATE log_url;
TRUNCATE log_url_info;
TRUNCATE log_visitor;
TRUNCATE log_visitor_info;
TRUNCATE log_visitor_online;
TRUNCATE report_viewed_product_index;
TRUNCATE report_compared_product_index;
TRUNCATE report_event;
TRUNCATE index_event;
TRUNCATE catalog_compare_item;

Optimize magento database Log Cleaning via Admin

  1. In the Magento Admin, go to System > Configuration.
  2. In the left menu under Advanced click on System.
  3. Under “Log Cleaning”, change “Enable Log Cleaning” to YES and configure the Save Log for 15 days:
  4. Click “Save Config”.

Optimize magento database by log cleaning

Optimize magento database Log.php

The shell utility log.php can be configured as a cron job or run manually to clean on-the-fly.

From the Magento root directory, type:

php −f shell/log.php clean

The –days switch can be used to specify how many days back to save.

Manual Cleaning via PhpMyAdmin.

This is the most efficient way to clean the logs for those more comfortable working with databases. It is faster than the built-in Magento tools, and it allows you to clean a couple of other tables not included in those tools.

  • Open the database in PhpMyAdmin via the Siteworx Control Panel.
  • In the right (main) frame, select the check box for the following tables:
dataflow_batch_export
dataflow_batch_import
log_customer
log_quote
log_summary
log_summary_type
log_url
log_url_info
log_visitor
log_visitor_info
log_visitor_online
report_viewed_product_index
report_compared_product_index
report_event
  • At the bottom of the page, click the drop-down box that says “With Selected:” and select “Empty”.
  • A confirmation screen will appear. Click “Yes”. This will truncate all of the selected tables.
