How to create rotating log file with Laravel and Monlog

问题

I'm trying to create my own rotating log file in Laravel using Monolog, however, the file rotation is not working and I don't know why.

I've created an artisan command that runs once per day, and keeps a log of it's activity. I want old versions of this file to be deleted after 2 days. In other words only the log of today's run, as well as yesterday's run should exist.

At the beginning of my artisan command, I have the following code:

$log = new Logger('MyCustomLog');
$log->pushHandler(new RotatingFileHandler(storage_path().'/logs/mycustomlog.log'), 2);

Then, throughout the command, I log information to it:

$log->addInfo('Info to log');

It seemed pretty straightforward to me, but it's simply not working. The log files are being generated correctly, but they are never getting deleted. I see the following in my app/storage/logs folder:

mycustomlog-2015-01-30.log
mycustomlog-2015-01-31.log
mycustomlog-2015-02-01.log
mycustomlog-2015-02-02.log
mycustomlog-2015-02-03.log

I would expect to see only the last 2 files. What am I doing wrong here?

回答1:

One of your bracket did get a bit out of place. You have to pass the number of log files to the constructor of RotatingFileHandler and not as second argument to pushHandler():

$log->pushHandler(new RotatingFileHandler(storage_path().'/logs/mycustomlog.log', 2));
//                                                                                ^
