During the execution of Symfony Commands, I want to log messages to a different file. I have read the Symfony and Monolog documentation, and it should work like I describe here. (Note that I know messages from the 'doctrine', 'event', ... channels will still be logged by the main handler, but that doesn't matter for me)
In my config.yml
, I have this:
monolog:
channels: [commandline]
handlers:
main:
type: stream
path: "%kernel.logs_dir%/%kernel.environment%.main.log"
level: debug
channels: [!commandline]
commandline:
type: stream
path: "%kernel.logs_dir%/%kernel.environment%.commandline.log"
level: debug
channels: commandline
stdout:
type: stream
path: "php://stdout"
level: debug
channels: commandline
mail:
type: stream
action_level: alert
handler: buffered_mail
buffered_mail:
type: buffer
handler: swift
swift:
type: swift_mailer
from_email: some@email.com
to_email: some@email.com
subject: "Something went wrong"
level: alert
I'm expecting to have 2 log-files: dev.main.log
and dev.commandline.log
. But I'm still having a third log-file: dev.log
that logs all messages. I don't seem to find where that loghandler is defined and how I can prevent it from logging things...
If anyone could point me in the right direction, that would be nice!
btw, i'm using:
EDIT
There is no monolog
section in the config_dev.yml
REMOVE monolog.handlers.main
from config_dev.yml
.
It usally contains path: "%kernel.logs_dir%/%kernel.environment%.log"
config _dev.yml (default)
monolog:
handlers:
main: # <- remove this handler
type: stream
path: "%kernel.logs_dir%/%kernel.environment%.log" #<- logs/dev.log
level: debug
Remove the main
handler from this config file.
If anyone comes across this and is still interested in why this happens, the debug handler is injected in the \\Symfony\\Bundle\\MonologBundle\\DependencyInjection\\Compiler\\DebugHandlerPass::process() method...
class DebugHandlerPass implements CompilerPassInterface
{
// ...
public function process(ContainerBuilder $container)
{
if (!$container->hasDefinition('profiler')) {
return;
}
if (!$container->getParameter('kernel.debug')) {
return;
}
$debugHandler = new Definition('%monolog.handler.debug.class%', array(Logger::DEBUG, true));
$container->setDefinition('monolog.handler.debug', $debugHandler);
foreach ($this->channelPass->getChannels() as $channel) {
$container
->getDefinition($channel === 'app' ? 'monolog.logger' : 'monolog.logger.'.$channel)
->addMethodCall('pushHandler', array(new Reference('monolog.handler.debug')));
}
}
}
As you can see, this pushes a new handler on to every registered channel, thus overriding any other handlers that might already have been added.
