为flask应用程序配置graylog日志处理程序和中间件
Flask-Graylog的Python项目详细描述
这是一个Flask扩展，允许您配置一个Graylog日志处理程序，并配置中间件将每个请求/响应记录到graylog。
安装
您可以通过pip安装它
pip install Flask-Graylog
用法
您只需导入并初始化应用程序即可
# Import dependenciesfromflaskimportFlaskfromflask.ext.graylogimportGraylog# Configure app and Graylog loggerapp=Flask(__name__)graylog=Graylog(app)# Log to grayloggraylog.info('Message',extra={'extra':'metadata',})# Use graylog log handler in another loggerimportlogginglogger=logging.getLogger(__name__)logger.addHandler(graylog.handler)logger.info('Message')
配置选项
以下选项可用于配置灰色日志记录器。
fromflaskimportFlaskfromflask.ext.graylogimportGraylogapp=Flask(__name__)# Use configuration from `app`app.config['GRAYLOG_HOST']='10.1.1.1'graylog=Graylog(app)# Provide configurationconfig={'GRAYLOG_HOST':'10.1.1.1'}graylog=Graylog(app,config=config)
- GRAYLOG_HOST-要向[默认值：'localhost']发送消息的主机
- GRAYLOG_PORT-发送消息的端口[默认值：12201]
- GRAYLOG_FACILITY-要使用[默认值：'flask']报告的工具
- GRAYLOG_EXTRA_FIELDS-是否包含每条消息中的额外数据[默认值：true]
- GRAYLOG_ADD_DEBUG_FIELDS-是否应在每条消息中添加额外的python调试字段[默认值：true]
- GRAYLOG_CONFIGURE_MIDDLEWARE-是否设置中间件来记录每个响应[默认值：true]
