How to log Messages to different Files
How to log Messages to different Files¶
The Symfony Standard Edition contains a bunch of channels for logging: doctrine,
event, security and request. Each channel corresponds to a logger
service (monolog.logger.XXX) in the container and is injected to the
concerned service. The purpose of channels is to be able to organize different
types of log messages.
By default, Symfony2 logs every messages into a single file (regardless of the channel).
Switching a Channel to a different Handler¶
Now, suppose you want to log the doctrine channel to a different file.
To do so, just create a new handler and configure it like this:
- YAML
1 2 3 4 5 6 7 8 9 10
monolog: handlers: main: type: stream path: /var/log/symfony.log channels: !doctrine doctrine: type: stream path: /var/log/doctrine.log channels: doctrine
- XML
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
<monolog:config> <monolog:handlers> <monolog:handler name="main" type="stream" path="/var/log/symfony.log"> <monolog:channels> <type>exclusive</type> <channel>doctrine</channel> </monolog:channels> </monolog:handler> <monolog:handler name="doctrine" type="stream" path="/var/log/doctrine.log" /> <monolog:channels> <type>inclusive</type> <channel>doctrine</channel> </monolog:channels> </monolog:handler> </monolog:handlers> </monolog:config>
Yaml specification¶
You can specify the configuration by many forms:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | channels: ~ # Include all the channels
channels: foo # Include only channel "foo"
channels: !foo # Include all channels, except "foo"
channels: [foo, bar] # Include only channels "foo" and "bar"
channels: [!foo, !bar] # Include all channels, except "foo" and "bar"
channels:
type: inclusive # Include only those listed below
elements: [ foo, bar ]
channels:
type: exclusive # Include all, except those listed below
elements: [ foo, bar ]
|
Creating your own Channel¶
You can change the channel monolog logs to one service at a time. This is done
by tagging your service with monolog.logger and specifying which channel
the service should log to. By doing this, the logger that is injected into
that service is preconfigured to use the channel you've specified.
For more information - including a full example - read "monolog.logger" in the Dependency Injection Tags reference section.
