Logging

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.

<env>.log

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.

php.log

By default Pimcore writes PHP-Engine Log Messages to the file php.log. You can change this by add the following to your symfony config:

monolog:
    handlers:
        error:
            type: stream
            path: "%kernel.logs_dir%/own_php.log"
            level: error

usagelog.log

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:

pimcore:
    general:
        disable_usage_statistics: true

Example Entry:

2021-04-26T13:18:35+0200 : 2|Pimcore\Bundle\AdminBundle\Controller\Admin\Document\PageController::saveAction|pimcore_admin_document_page_save|{"task":"publish","id":"1","data":"{\"cImage_0\":{\"data\":{\"id\":337,\"path\":\"\\\/..."}
2021-04-26T13:18:35+0200 : 2|Pimcore\Bundle\AdminBundle\Controller\Admin\Asset\AssetController::getImageThumbnailAction|pimcore_admin_asset_getimagethumbnail|{"id":"3","alt":"","height":"undefined","thumbnail":"portalCarousel","pimcore_editmode":"1"}

Explanation

Value (from the example above)	Description
2021-04-26T13:18:35+0200	Timestamp
2	User-ID
Pimcore\Bundle\AdminBundle\Controller\Admin\Document\PageController::saveAction	Module\Controller::Action
pimcore_admin_document_page_save	Route name
{"task":"pub .... }	Request Parameters (shortened & censored)

redirect.log

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.

Example

2021-04-26T14:03:20+0200 : 10.242.2.255          Custom-Redirect ID: 1, Source: /asdsad/redirectsource/asd -> /en/Events

info

Redirects are logged into a redirect monolog log channel at info level. By default, Pimcore logs that channel into var/log/redirect.log. Of course, the corresponding monolog handler configuration can be adapted as needed.

Writing Your Own Log Files

To create a custom log entry, we need to create the monolog log channels and log handlers configuration. Here is an example on how to log in a custom filename called custom.log

monolog:
    handlers:
        custom_handler:
            level:    debug
            type:     stream
            path:     '%kernel.logs_dir%/custom.log'
            channels: [custom_log]
    channels: [custom_log, some_other_channel]

It is possible to inject the Psr\Log\LoggerInterface by changing the variable name eg. $customLogLogger (camel case channel name + Logger) and Symfony will automatically wire the specified channel.

class SomeService {
    public function __construct(\Psr\Log\LoggerInterface $customLogLogger)
    {
        $customLogLogger->debug('Test Message');
    }
}
