## Friendica\Util\Logger
This namespace contains the different implementations of a Logger.
### Configuration guideline
The following settings are possible for `logger_config`:
- `monolog`: A Logging framework with lots of additions (see [Monolog](https://github.com/Seldaek/monolog/)). There are just Friendica additions inside the Monolog directory
- [`stream`](StreamLogger.php): A small logger for files or streams
- [`syslog`](SyslogLogger.php): Prints the logging output into the syslog
[`VoidLogger`](VoidLogger.php) is a fallback logger without any function if no debugging is enabled.
[`ProfilerLogger`](ProfilerLogger.php) is a wrapper around an existing logger in case profiling is enabled for Friendica.
Every log call will be saved to the `Profiler` with a timestamp.
### Implementation guideline
Each logging implementation should pe capable of printing at least the following information:
- An unique ID for each Request/Call
- The process ID (PID)
- A timestamp of the logging entry
- The critically of the log entry
- A log message
- A context of the log message (f.e which user)
If possible, a Logger should extend [`AbstractFriendicaLogger`](AbstractFriendicaLogger.php), because it contains additional, Friendica specific business logic for each logging call.
Using AbstractFriendicaLogger makes the logger capable of adding profiling data for each log call.
