I've read a lots of questions here and read some documentation. But Still don't understand how to format a JSON value with monolog.
Here my code that is not working:
php $formatter = new JsonFormatter(); $log->addInfo($formatter->format(['foo' => 'bar']));
The output is always in one line instead of in a formatted way.
bash [2016-03-02 07:45:57] parameters.INFO: {"foo":"bar"} [] []
The JsonFormatter is meant to be used for formatting the output.
$log = new \Monolog\Logger( 'my_log' );
$stream_handler = new \Monolog\Handler\StreamHandler( 'my_log_file.log' );
$stream_handler->setFormatter( new \Monolog\Formatter\JsonFormatter() );
$log->pushHandler( $stream_handler );
$log->addError( 'foo' );
Without the JsonFormatter you get the normal output:
[2016-04-04 16:37:55] my_log.ERROR: foo [] []
With the JsonFormatter you get JSON output:
{"message":"foo","context":[],"level":400,"level_name":"ERROR","channel":"my_log","datetime":{"date":"2016-04-04 16:38:14.102258","timezone_type":3,"timezone":"UTC"},"extra":[]}
