关于 Logging Level

[Livid]

如果需要用整数来表示 FATAL / ERROR / DEBUG 等等 level 的话，目前在业界有没有一套标准之类的？

[ivenvd]

为啥要用整数表示呢，可以直接用 logging.debug() 之类的函数吧……
非要用的话可以用 logging.DEBUG ……

不知道有没有整型的标准，不过不妨把kern_levels.h里定义的字符串当成hex值来看

@efi 谢谢大神。

另外 php的error也不错

@thbourlove
这个前面是基于RFC2119，是规定 RFC 本身的用语，并不符合楼主的需求。而后面虽然也有LogLevel，但都是一些字符常数，目测也是根据RFC5424或RFC3164而来...

679 # from <linux/sys/syslog.h>:
680 # ======================================================================
681 # priorities/facilities are encoded into a single 32-bit quantity, where
682 # the bottom 3 bits are the priority (0-7) and the top 28 bits are the
683 # facility (0-big number). Both the priorities and the facilities map
684 # roughly one-to-one to strings in the syslogd(8) source code. This
685 # mapping is included in this file.
686 #
687 # priorities (these are ordered)
688
689 LOG_EMERG = 0 # system is unusable
690 LOG_ALERT = 1 # action must be taken immediately
691 LOG_CRIT = 2 # critical conditions
692 LOG_ERR = 3 # error conditions
693 LOG_WARNING = 4 # warning conditions
694 LOG_NOTICE = 5 # normal but significant condition
695 LOG_INFO = 6 # informational
696 LOG_DEBUG = 7 # debug-level messages


python的源码里也是一致的.

整数不标准，不过名字很通用，用法都一样
