Enable logging

Debug logging

By default, Commerce writes to the debug log (<install_directory>/var/log/debug.log) when it is in default or develop mode, but not when it is in production mode. Use the bin/magento setup:config:set --enable-debug-logging command to change the default value.

To enable debug logging

1. Use the setup:config:set command to enable debug logging for the current mode.

   bin/magento setup:config:set --enable-debug-logging=true
   

2. Flush the cache.

   bin/magento cache:flush
   

To disable debug logging

1. Use the setup:config:set command to disable debug logging for the current mode.

   bin/magento setup:config:set --enable-debug-logging=false
   

2. Flush the cache.

   bin/magento cache:flush
   

Database logging

By default, Commerce writes database activity logs to the <install-dir>/var/debug/db.log file.

To enable database logging

1. Use the dev:query-log command to enable or disable database logging.

   bin/magento dev:query-log:enable
   

   bin/magento dev:query-log:disable
   

2. Flush the cache.

   bin/magento cache:flush
   

Cron logging

With the release of version 2.3.1, Commerce now creates a separate cron log.
Commerce recently made cron logging more verbose, which provided more information but lengthened the system.log considerably.
Moving cron info to a dedicated log makes both logs easier to read.

By default, Commerce writes cron info to the <install-directory>/var/log/cron.log file.

Syslog logging

By default, Commerce writes syslog logs to the operating system syslog file.
As of Commerce 2.3.1, you must use the magento command to enable or disable the syslog.
The setting in the Admin has been removed.

To enable syslog logging

Logging to syslog is disabled by default.

1. Use the setup:config:set command to change the dev/syslog/syslog_logging database value to true.

   bin/magento setup:config:set --enable-syslog-logging=true
   

2. Flush the cache.

   bin/magento cache:flush
   

To disable syslog logging

1. Use the setup:config:set command to change the dev/syslog/syslog_logging database value to false.

   bin/magento setup:config:set --enable-syslog-logging=false
   

2. Flush the cache.

   bin/magento cache:flush
