This application fully integrates in to the Dashboard to show enabled / disabled maintenance applications at a glance on the current domain.
- Automatic detection and installation of new maintenance services when App Defaults is executed.
- Each application can execute on a per domain basis making it possible for a per tenant limit
- Simple function call for each class enabling a complete customization for the maintenance application. This opens a new host of capabilities like filesystem quotas or archiving old database records.
- Built-in logging is available via the maintenance_service::log_write() method and viewable in the new Maintenance Logs viewer.
- Default setings are done automatically per maintenance application when registered. Each application can set the number of days to retain data both globally and per domain under the Maintenance category.
Utilizes the new service class to allow for easy installation and a standardize comprehensive command line interpreter. With the ability to reload the maintenance service settings without a restart of the service.
Now simply type ./maintenance_service -r or ./maintenance_service --reload and the settings will be reloaded.
Utilizes the new settings class to allow for independent loading of the default settings or getting the current database connection. Simply use $database = $settings->database(); to get the already connected database.
Shows the maintenance applications currently active and their retention days on the filesystem and database. Easily modify the retention days for each registered application.
Quickly create new maintenance applications by adding a public static function database_maintenance(settings $settings): void {} to handle any database work and/or a public static function filesystem_maintenance(settings $settings): void {} to handle any filesystem work in your existing class or create a new class that uses one or both methods. The maintenance application will automatically find it and register the application when App Defaults has been executed. Once the application is enabled in default settings, the application will execute on the next cycle.
