For targeted problem analysis, access to messages with less importance might possibly be needed. Especially searches for the cause of performance problems or otherwise unexplainable behavior might make a temporary change of the log level configuration sensible and useful.
To define the minimum importance required for messages to be logged, the constant CONST_LOG_LEVEL_FILE has to be added to the config.php file and set to the respective value.
Possible values:
•FATAL: Critical error (Program termination)
•ERROR: Error (Exception caught, processing was handled differently)
•WARNING: Unexpected situation occurred (default value)
•INFO: General information (Program execution)
•DEBUG: Detailed information (Locating errors)
For example, if you define the value INFO as log level, all messages with an importance from INFO to FATAL will be logged.
Attention: Please note, reducing the minimum importance of messages you want to log can lead to a significant amount of data (under circumstances multiple hundreds of MB per hour) written into the log files over a short amount of time. Please ensure that enough free storage space is available for the output directory and after logging all necessary messages, remove the constant CONST_LOG_LEVEL_FILE from the config.php file again or set its value back to the default value WARNING.
By setting the constant CONST_LOGGING_DISABLED to true, logging can also be deactivated.
The logging output of ongoing instances (e.g. step and process table actions) is recorded in one file per instance (<processname>_<processid>_<date>.log). This way, instance-related actions can be tracked more easily. If you want to record the logging output in files separated per object type instead (e.g. step, incident), you can disable the instance-related logging with the following entry in the configuration file:
<?php
// some constants ...
return [
'db' => [
// database connection data
],
// deactivate logging in separate files for process instance data
'log' => [
'separateLogPerProcessInstance' => false,
],
];
