README

This extension replaces the default CiviCRM log channels to send all logs to stderr (currently). This is especially useful when running CiviCRM inside a Docker container, as it allows logs to be consolidated and managed by the container runtime.

Features

• Redirects all CiviCRM logs to stderr
• Simplifies log management in containerized environments

Usage

1. Install the extension in your CiviCRM installation.
2. Enable the extension from the CiviCRM admin interface.
3. Logs will now appear in the container's standard error output.

Configuration

Log Level Configuration

The minimum log level can be set three ways, highest precedence first:

1. PHP constant in civicrm.settings.php: define('CIVICRM_CONTAINER_LOGS_LEVEL', 'warning');
2. Environment variable (recommended for containerised deployments): CIVICRM_CONTAINER_LOGS_LEVEL=warning — picked up natively by CiviCRM's SettingsManager because the setting metadata declares is_env_loadable: TRUE, global_name: 'CIVICRM_CONTAINER_LOGS_LEVEL'.
3. $civicrm_setting in civicrm.settings.php: $civicrm_setting['domain']['container_logs_level'] = 'warning';

The setting is declared is_constant: TRUE, so attempts to write via Civi::settings()->set(...) / the API / the admin UI are rejected with a helpful error pointing to the three supported sources above.

Default: debug (everything passes through).

Accepted values are any Monolog level name (see \Monolog\Level; values from RFC 5424):

• DEBUG (100), INFO (200), NOTICE (250), WARNING (300),
• ERROR (400), CRITICAL (500), ALERT (550), EMERGENCY (600).

Requirements

• PHP8.1 or newer
• CiviCRM installation
• Docker container environment (recommended)
