+ <seealso marker="#macros">macros</seealso> should be used. For instance,
+ to log a new error log event:</p>
+ <code>
+?LOG_ERROR("error happened because: ~p",[Reason]). %% With macro
+logger:error("error happened because: ~p",[Reason]). %% Without macro
+ </code>
+ <p>This log event will then be sent to the configured log handlers which

+ <p>Logger can be configured either when the system starts through
+ <seealso marker="config">configuration parameters</seealso>,
+ or at run-time by using the <seealso marker="logger">logger</seealso>

+ <title>Application configuration parameters</title>
+ <p>Logger is best configured by using the configuration parameters
+ of kernel. There are three possible configuration parameters:
+ <seealso marker="#logger"><c>logger</c></seealso>,
+ <seealso marker="kernel_app#logger_level"><c>logger_level</c></seealso>,
+ <seealso marker="kernel_app#logger_sasl_compatible"><c>logger_sasl_compatible</c></seealso> and
+ <seealso marker="kernel_app#logger_log_progress"><c>logger_log_progress</c></seealso>.
+ logger_level, logger_sasl_compatible and logger_log_progress are described in the
+ <seealso marker="kernel_app#configuration">Kernel Configuration</seealso>,
+ while <c>logger</c> is described below.</p>
+ <section>
+ <marker id="logger"/>
+ <title>logger</title>
+ <p>The <c>logger</c> application configuration parameter is used to configure
+ three different logger aspects; handlers, logger filters and module levels.
+ The configuration is a list containing tagged tuples that look like this:</p>
+ <taglist>
+ <tag><c>DisableHandler = {handler,default,undefined}</c></tag>
+ <item>Disable the default handler. This will allow another application
+ to add its own default handler. See <seealso marker="logger#add_handlers/1">
