There are several different kinds of logs in Pimcore. All of them are located under /var/log and get rotated as well as compressed automatically on every day (7 days retention) by the maintenance command.


This is definitely one of the most important logs and also the default logging location.

Pimcore uses Symfony default monolog logging with following channels: pimcore, pimcore_api, session. For details see Symfonys monolog docs.


By default Pimcore writes PHP-Engine Log Messages to the file php.log. You can change this using constant PIMCORE_PHP_ERROR_LOG that is used to set PHP's error_log Configuration.


In this log you can find every action done within the Pimcore Backend Interface. It can be deactivated by configuring disable_usage_statistics in config/config.yaml:

        disable_usage_statistics: true

Sometimes it's necessary to debug redirects, for example when a redirect ends in an infinite loop. In this log you can see every request where a redirect takes action.

2021-04-26T14:03:20+0200 :          Custom-Redirect ID: 1, Source: /asdsad/redirectsource/asd -> /en/Events

Writing your own log files

You can add your own logging functionality using Pimcore's log writer. You can call a static function like this:

Custom log entry
\Pimcore\Log\Simple::log($name, $message);

The $name variable defines the filename of the log file, "mylog" will write a file to /var/log/mylog.log (extension is added automatically). If the file does not yet exist it will be created on the fly.

The message is the line that will be written to the log. A date and time will also be prepended automatically to each log entry.
