POE::Component::Logger - A POE logging class
In your startup code somewhere:
POE::Component::Logger->spawn(ConfigFile => 'log.conf');
And later in an event handler:
POE::Component::Logger provides a simple logging component that uses Log::Dispatch::Config to drive it, allowing you to log to multiple places at once (e.g. to STDERR and Syslog at the same time) and also to flexibly define your logger's output.
It is very simple to use, because it creates a Logger::log method (yes, this is namespace corruption, so shoot me). If you don't like this, feel free to post directly to your logger as follows:
$kernel->post('logger', 'log', "An error occurred: $!");
In fact you have to use that method if you pass an Alias option to spawn (see below).
All logging is done in the background, so don't expect immediate output - the output will only occur after control goes back to the kernel so it can process the next event.
The spawn class method can take two options. A required ConfigFile option, which specifies the location of the config file as passed to Log::Dispatch::Config's
configure()method (note that you can also use an object here, see Log::Dispatch::Config for more details). The other available option is Alias which you can use if you wish to have more than one logger in your POE application. Note though that if you specify an alias other than the default 'logger' alias, you will not be able to use the
Logger->logshortcut, and will have to use direct method calls instead.
This is used to perform a logging action. You may either pass a string, or a hashref. If you pass in a string it is logged at the level specified in
$POE::Component::Logger::DefaultLevel, which is 'warning' by default. If you pass in a hashref it is expanded as a hash and passed to Log::Dispatch's
The following states are available on the POE logging session:
Logger->log(), except you may use a different alias if posting direct to the kernel, for example:
$kernel->post( 'error.log', 'log', "Some error"); $kernel->post( 'access.log', 'log', "Access Details");
These states simply log at a different level. See Log::Dispatch for further details.
# logs to screen (STDERR) and syslog dispatchers = screen syslog [screen] class = Log::Dispatch::Screen min_level = info stderr = 1 format = %d %m %n [syslog] class = Log::Dispatch::Syslog min_level = warning
