我正在以下列方式创建我的记录器:
Logging.color_scheme( 'bright',
:levels => {
:info => :green,
:warn => :yellow,
:error => :red,
:fatal => [:white, :on_red]
},
:date => :blue,
:logger => :cyan,
:message => :magenta
)
@logger = Logging.logger['main_logger']
@logger.add_appenders(
Logging.appenders.stdout,
Logging.appenders.file('file',
:filename => LOG_FILE_PATH,
:layout => Logging.layouts.pattern(:pattern => '[%d] %-5l %c: %m\n')
)
)
我想将线程id添加到每条日志消息(Thread.current.object_id),有没有办法可以做到?
答案 0 :(得分:5)
您必须使用映射的诊断上下文'mdc'(请参阅https://github.com/TwP/logging/blob/master/examples/mdc.rb)
以下是我的工作:
Logging.appenders.stdout(
'stdout',
:layout => Logging.layouts.pattern(
:pattern => '%d %-5l [%X{tid}]: %m\n',
:date_pattern => "%d/%m/%Y %H:%M:%S",
:color_scheme => 'bright'
),
)
并在你的帖子中,指出潮汐字段的值:
Logging.mdc['tid'] = Thread.current.object_id
