log( $category, $level, @message )¶

The combination of category and level determine whether the the log messages are emitted to any of the log destinations. Destinations are set using the "log_config" method, and categories are configured using the "log_flags" method.

The @message list will be joined by a space character, and a newline appended if the last message doesn't contain one itself. Messages are prepended with the first character of their $category, and then indented proportionally to their $level.

log_config( \%config )¶

A "Log::Dispatch::Config" configuration (hash ref), meaning multiple log targets may be specified with different minimum level thresholds. There is a default configuration which emits messages to your screen (console) with no minimum threshold:

 {
     dispatchers => ['screen'],
     screen => {
         class => 'Log::Dispatch::Screen',
         min_level => 'debug',
     },
 };

log_flags( \@categories | \%category_level_map )¶

The user is expected to specify which log categories they are interested in, and at what levels. If a category is used in the application for logging but not specified, then it is deemed disabled. Hence, even though the default destination log level is "debug", no messages are emitted until a category is enabled.

In the array reference form, the list should contain category names, and they will all be mapped to the "error" level:

 $logger->log_flags([qw/
     network
     disk
     io
     cpu
 /]);

In the hash reference form, the keys should be category names and the values log levels from the list below (ordered such that each level "includes" the levels above):

 emergency
 alert
 critical
 error
 warning
 notice
 info
 debug

For example:

 $logger->log_flags({
     network => 'info',
     disk    => 'debug',
     io      => 'critical',
     cpu     => 'debug',
 });

Messages at or above the specified level will be passed on to the "Log::Dispatch" target, which may then specify an overriding threshold.

" Net::CLI::Interact-"default_log_categories() >>¶

Not a part of this class, but the only way to retrieve a list of the current log categories used in the Net::CLI::Interact distribution source. Does not take into account any log categories added by the user.

log_stamp( $boolean )¶

Enable (the default) or disable the display of high resolution interval timestamps with each log message.

log_category( $boolean )¶

Enable (the default) or disable the display of the first letters of the category name with each log message.

log_start( [$seconds, $microseconds] )¶

Time of the start for generating a time interval when logging stamps. Defaults to the result of "Time::HiRes::gettimeofday" at the point the module is loaded, in list context.

would_log( $category, $level )¶

Returns True if, according to the current "log_flags", the given $category is enabled at or above the threshold of $level, otherwise returns False. Note that the "Log::Dispatch" targets maintain their own thresholds as well.
