[The Dancer2 plugin was contributed by Andrew Beverley]
This logger allows the use of the many logging backends available in Log::Report. It will process all of
the Dancer2 log messages, and also allow any other module to use the same logging facilities. The same
log messages can be sent to multiple destinations at the same time via flexible dispatchers.
If using this logger, you may also want to use Dancer2::Plugin::LogReport
Many log back-ends, like syslog, have more levels of system messages. Modules who explicitly load this
module can use the missing "assert", "notice", "panic", and "alert" log levels. The "trace" name is
provided as well: when you are debugging, you add a 'trace' to your program... it's just a better name
than 'debug'. You will need to load Log::Report in order to use the additional levels; if doing so
directly within a Dancer2 application (not a sub-module), then you will either need to load Log::Report
with "syntax, 'LONG'" or use Dancer2::Plugin::LogReport to prevent namespace clashes.
LogFormat
If using this module on its own (such as a drop-in replacement for Dancer2::Logger::Syslog), then the
logging format is configured as with any other Dancer logger. If using this module with
Dancer2::Plugin::LogReport, then log_format is ignored and messages are not formatted, in order to keep
the message format consistent regardless of where the message was generated (be it another module using
Log::Report, the plugin, or Dancer itself). In this case, the log format should be configured using the
applicable dispatcher (such as Log::Report::Dispatcher::Syslog::new(format)).
If also using with the Log::Report logging functions, then you probably want to set a very simple
"logger_format", because the dispatchers do already add some of the fields that the default "simple"
format adds. For instance, to get the filename/line-number in messages depends on the dispatcher 'mode'
(f.i. 'DEBUG').
You also want to set the Dancer2 log level to "debug", because level filtering is controlled per
dispatcher (as well).
See "DETAILS" in Dancer2::Plugin::LogReport for examples.
