方案 之 日志统一

主要步骤

1. 使用egg自带/封装插件
2. 统一Nodejs日志告警规则

报警触发规则

1. 五分钟同一项目遇到Erorr，发送一次邮件、#钉钉推送、通知；
2. 一分钟同一项目遇到Fatal日志，直接发短信通知✔、邮件、#钉钉； （主机名区分）
3. 保持原有java格式日志的告警不不变，做规则迁移。

规则详情

存放地址

1. nodejs自身日志：/var/log/nodejs/项目名-xxx.log 事例例：/var/log/nodejs/项目名-xxx.log
2. java要求日志：/var/log/nodejs/项目名-java-xxx.log 事例例：/var/log/nodejs/项目名-java-xxx.log

日志内容

Nodejs日志统一格式： 日期 + 日志等级 + [线程ID]（可能没有） + 日志内容
换行行转义一下：

str.replace(/\n/g, '\\n')

5. 所有日志后面统一加上UUIDV4，用作同一时间单挑日志的唯一标识：
