# Logging

You can use the logging class to output to a file.


use ```$log->info(The Message');```1

Logging levels are:
```
'DEBUG' => 0,
        'INFO' => 1,
        'WARNING' => 2,
        'ERROR' => 3,
    ];
```

It's recommended that production is set to ERROR. 
You set the log level in /App/config.php under 'loglevel' => 'ERROR'
If you are using CORXN a health check is run every 30 seconds which would fill the log file with info.
