这一篇中的日志规则可以有效的借鉴:
日志
日志是发现问题、查看问题一个最常用的手段。日志质量往往被忽视,没有日志使用上的明确约定。重视 Log 的使用,提高 Log 的信息浓度。日志过多、过于混乱,会导致有用的信息被淹没。
要有效利用这个工具要注意:
严格约定WARN、ERROR级别记录的内容
WARN 表示可以恢复的问题,无需人工介入。
ERROR 表示需要人工介入问题。
有了这样的约定,监管系统发现日志文件的中出现 ERROR 字串就报警,又尽量减少了发生。过多的报警会让人疲倦,使人对报警失去警惕性,使 ERROR 日志失去意义。再辅以人工定期查看 WARN 级别信息,以评估系统的“亚健康”程度。
日志中,尽量多的收集关键信息
哪些是关键信息呢?
出问题时的现场信息,即排查问题要用到的信息。如服务调用失败时,要给出使用 Dubbo 的版本、服务提供者的 IP、使用的是哪个注册中心;调用的是哪个服务、哪个方法等等。这些信息如果不给出,那么事后人工收集的,问题过后现场可能已经不能复原,加大排查问题的难度。
如果可能,给出问题的原因和解决方法。这让维护和问题解决变得简单,而不是寻求精通者(往往是实现者)的帮助。
同一个或是一类问题不要重复记录多次
同一个或是一类异常日志连续出现几十遍的情况,还是常常能看到的。人眼很容易漏掉淹没在其中不一样的重要日志信息。要尽量避免这种情况。在可以预见会出现的情况,有必要加一些逻辑来避免。
如为一个问题准备一个标志,出问题后打日志后设置标志,避免重复打日志。问题恢复后清除标志。
虽然有点麻烦,但是这样做保证日志信息浓度,让监控更有效。
