Log

Log

By default October is configured to create a single log file for your application which is stored in the storage/logs directory. You may write information to the logs using the Log facade.

$user = User::find(1);
Log::info('Showing user profile for user: '.$user->name);

The logger provides the eight logging levels defined in RFC 5424 (opens new window): emergency, alert, critical, error, warning, notice, info and debug.

Log::emergency($error);
Log::alert($error);
Log::critical($error);
Log::error($error);
Log::warning($error);
Log::notice($error);
Log::info($error);
Log::debug($error);

# Contextual Information

An array of contextual data may also be passed to the log methods. This contextual data will be formatted and displayed with the log message:

Log::info('User failed to login.', ['id' => $user->id]);

# Helper Functions

There are some global helper methods available to make logging easier. The trace_log function is an alias for Log::info with support for using arrays and exceptions as the message.

// Write a string value
$val = 'Hello world';
trace_log('The value is '.$val);

// Dump an array value
$val = ['Some', 'array', 'data'];
trace_log($val);

// Trace an exception
try {
    //
}
catch (Exception $ex) {
    trace_log($ex);
}

The trace_sql function enables database logging, when called it will log every command sent to the database. These records only appear in the system.log file and will not appear in the backend panel log as this is stored in the database and would result in a feedback loop.

trace_sql();

Db::table('users')->count();

// select count(*) as aggregate from users
