dueros node tracer

usage

• init: 按照顺序一条中排序 内部使用log4js配置 tracer.initLog(require('./conf/log4js_config')[env], 'app');

let t = new tracer('dcs-utils', req.logid, [ { key: logid, default: '-' }, { key:path }, { key:request, } ]);

• 单条打印：

t.debug('request:%j', req.body);

• 收集日志 最终一条输出：

t.gather('path', req.path.toLowerCase()); t.gather('client_ip', req.ip); t.gather('header', req.headers); t.gather('pv_lost', 0); t.dumps();

• global use tracer.debug('logid:%s request:%j', this.logid, req.body);
