Please see L for more on middleware. +=head1 TRACING + +B Tracing replaces the functionality of L. For now both +interfaces will be supported but it is suggested that you become familiar with +the new interface and begin using it. + +Application tracing is debugging information about the state of your L +application and a request / response cycle. This is often used when you want a +peek into the 'Catalyst Black Box' without needing to actually hack into the +core code and add debugging statements. Examples of application tracing include +startup information about loaded plugins, middleware, models, controllers and +views. It also includes details about how a request is dispatched (what actions +in what controllers are hit, and approximately how long each took) and how a +response is generated. Additional trace information includes details about errors +and some basic statistics on your running application. + +It is often the case when running an application in a development environment +for development purposes that you will enable tracing to assist you in your work. +However, application tracing is not strictly tied to environment so trace levels +are not automatically enabled based on any environment settings (although you are +allowed to set trace levels via configuration, which can be environment specific, +if you choose so). + +Application tracing is also not the same thing as logging. Logging is custom messages +that you've added to your custom application for the purposes of better understanding +your application and how effective your application is in achieving its goals. +Often logging is extended, unstructured meta data around your core business logic +such as details about when a user account is created or failed to be created, what +types of validation issues are occuring in your forms, page views, user engagement +and timestamps to help you understand your application performance. Basically this +is often information of business value that doesn't cleanly or meaningfully fit +into a database. Catalyst provides an interface for adding various kinds of +Loggers which can assist you in these tasks. Most Loggers allow one to log +messages at different levels of priority, such as debug, warning, critical, etc. +This is a useful feature since it permits one to turn the logging level down in +high traffic environments. In the past Catalyst tracing (previously called +'Debug') was conflated with log levels of debug, in that in order to enable +application tracing (or debugging) one was required to turn log level debug on +globally. Additionally, the Catalyst application tracing (or debugging) used +the defined logger to 'record' its messages. Neither is ideal since it leads +one to be forced to accept more logging than may be wished, and it also does +not allow one to separate development tracing from application debug logging. + +Application tracing fixes this issues by allowing you to turn on tracing +independently of setting your log level. It also lets you define a trace +log message handler separately from your logger. So for example you might +wish to send trace messages to STDOUT, but send your logging to Elasticsearch. +Here's an example: + + package MyApp; + + use Catalyst; + + __PACKAGE__->trace_level(1); + __PACKAGE__->trace_logger(sub { my $class = shift; ...}); + __PACKAGE__->setup; + +You may also configure tracing via configuration: + + package MyApp; + + use Catalyst; + + __PACKAGE__->config({ + trace_level => 1, + trace_logger => sub { my $class = shift; ...}, + }); + + __PACKAGE__->setup; + +B You cannot set tracing via configuration files if you are using +the L plugin, as that plugin is loaded too +late for it to be applied during all phases of setup. + +Or, you may set tracing via environment varables, for example: + + CATALYST_TRACE=1 perl script/myapp_server.pl + MYAPP_TRACE=1 perl script/myapp_server.pl + MYAPP_TRACE=1=/var/log/traces perl script/myapp_server.pl + +The order of precidence is that custom application environment variables +('MYAPP_TRACE') come first, followed by global environment variables +('CATALYST_TRACE'), followed by configuration settings and lastly application +defaults. + +For backwards compatiblity, we respect classic Catalyst debugging (L) in +the following way. If debugging is true, we automatically set +C and set the C to your the debug method of your +defined log object (basically it works just as described in L). In this +case $c->debug will also be set to true. + +Please note that if you set C but not debugging then debugging +($c->debug) will NOT be set to true. + +Please note that if you set BOTH trace_level and 'class' debugging, your trace +level and trace configuation is respected at a high priority, however the state +of the debug method will be set as requested (although overridden). This is +done for backcompatibility with applications that overloaded the debug method +in custom applications. + +Please note that when setting trace levels via environment, you may use an +extended form of the value, which opens a filehandled to a specified path +and sends all trace information there: + + MYAPP_TRACE=1=/var/log/traces perl script/myapp_server.pl + +This would override any other settings for L<\trace_logger>.
